looking first at fig4 and 5 , there is shown an apparatus 100 for use in closing tear 20 in meniscus 5 . more particularly , in one preferred form of the present invention , and still looking now at fig4 and 5 , a first needle 105 is first advanced so that its distal tip 110 is positioned within , but not completely through , meniscus 5 . next , as seen in fig6 , a second needle 115 is advanced completely through the meniscus , so that the distal tip 120 of second needle 115 is positioned on the far side of the meniscus . then , and looking now at fig7 - 9 , a snare 125 is advanced out the distal end 120 of second needle 115 . snare 125 is formed and arranged so that when the snare is in its fully - extended position ( fig9 ), the loop 130 of snare 125 is axially aligned with the longitudinal axis 135 of first needle 105 . to this end , snare 125 may comprise an elongated body 140 having the loop 130 set at its distal end , with loop 130 being set at an angle to the longitudinal axis of elongated body 140 . at least one of loop 130 and elongated body 140 comprises a resilient material , in order that loop 130 and elongated body 140 may be ( i ) received within second needle 115 , and ( ii ) loop 130 may project across the longitudinal axis 135 of first needle 105 when snare 125 is in its fully - extended position ( fig9 ). next , and looking now at fig1 , first needle 105 is advanced completely through meniscus 5 , so that the distal end 110 of first needle 105 extends through loop 130 of snare 125 . then first needle 105 is used to advance a suture 145 through loop 130 of snare 125 . this may be effected in a variety of ways . by way of example but not limitation , and looking now at fig1 - 12 , suture 145 may be pre - disposed within first needle 105 so that suture 145 is carried through the meniscus and through loop 130 of snare 125 with the advancement of first needle 105 . then a driver 150 may be used to eject the leading portion 145 l ( fig1 ) of suture 145 from the interior of first needle 105 . to this end , a slot 155 may be provided in first needle 105 to assist in ejecting leading portion 145 l of suture 145 from first needle 105 . finally first needle 105 is withdrawn , leaving leading portion 145 l of suture 145 extending through ( i ) meniscus 5 , and ( ii ) loop 130 of snare 125 . the approach shown in fig1 - 12 can be advantageous in many circumstances , since it works well with both braided suture and monofilament suture . in this respect it will be appreciated that braided suture is generally preferable for meniscal repairs , since it tends to form a smaller knot which is less susceptible to slipping . in an alternative approach , where suture 145 has sufficient column strength ( e . g ., where suture 145 comprises relatively thick monofilament suture ), after first needle 105 is advanced through meniscus 5 ( fig1 ) and through loop 130 of snare 125 , the suture can be pushed through first needle 105 so that leading portion 145 l of suture 145 extends through both meniscus 5 and loop 130 of snare 125 . then , while suture 145 is maintained in place , first needle 105 can be withdrawn , with the column strength of the suture ensuring that leading portion 145 l of suture 145 does not retreat from its position extending through meniscus 5 and loop 130 of snare 125 . of course , this latter approach does suffer from the disadvantage that it requires the use of suture with sufficient column strength ( e . g ., monofilament suture ) and hence this approach can be difficult to practice with conventional braided suture . regardless of the particular approach used to achieve the position shown in fig1 , once this position has been achieved , the next step is to carry leading portion 145 l of suture 145 back to the near side of the meniscus . more particularly , and looking now at fig1 - 15 , snare 125 is retracted back into second needle 115 , and then second needle 115 is withdrawn back through the meniscus , carrying leading portion 145 l of suture 145 with it . thus , at this point in the procedure , suture 145 will have been passed from the near side of the meniscus , across the meniscus and then back again . significantly , by appropriately positioning the first needle 105 and second needle 115 during the suture passing operation , the suture will extend across the tear 20 formed in meniscus 5 . next , the suture is tied down so as to close the tear in the meniscus . this may be done in a variety of ways which will be apparent to those skilled in the art in view of the present disclosure . however , in one preferred form of the invention , a trailing portion 145 t of suture 145 may be arranged in the form of a pre - formed , uncinched knot 160 disposed about the exterior of second needle 115 ( see , for example , fig1 and 14 ), with an intermediate portion 145 i of suture 145 being disposed within apparatus 100 . as a result of this construction , when snare 125 and second needle 115 carry leading portion 145 l of suture 145 back through the meniscus , they will also carry leading portion 145 l of suture 145 back through pre - formed , uncinched knot 160 ( fig1 ), which is itself formed from trailing portion 145 t of that same suture 145 . it will be appreciated that , as second needle 115 is withdrawn , pre - formed , uncinched knot 160 will slip off the end of second needle 115 , into direct contact with leading portion 145 l of suture 145 , as the suture passes back through itself . then , and looking now at fig1 , suture 145 is pulled taut so as to simultaneously ( i ) pull tear 20 closed , and ( ii ) tighten pre - formed knot 160 onto the suture , whereby to fix the suture in position and thereby close tear 20 in meniscus 5 . the trailing end 145 t of suture 145 can then be trimmed away in ways well known in the art , thereby leaving a low - profile suture fixation within the meniscus . looking now at fig1 and 18 , there is shown an apparatus 200 for use in closing tear 20 in meniscus 5 . more particularly , in one preferred form of the invention , and still looking now at fig1 and 18 , a first needle 205 is first advanced so that its distal tip 210 is positioned within , but not completely through , meniscus 5 . next , as seen as fig1 , a second needle 215 is advanced completely through the meniscus , so that the distal tip 220 of second needle 215 lies on the far side of the meniscus . then , and looking now at fig2 , first needle 205 is advanced all the way across meniscus 5 . then , and looking now at fig2 and 22 , a snare 225 is advanced out the distal end 220 of second needle 215 . snare 225 is formed and arranged so that when the snare is in its fully - extended position ( fig2 ), the loop 230 of snare 225 is axially aligned with the longitudinal axis 235 of second needle 215 . to this end , snare 225 may comprise an elongated body 240 having loop 230 set at its distal end , with loop 230 being aligned with the longitudinal axis of elongated body 240 . next , and looking now at fig2 , a suture holder 250 carrying a suture 245 is advanced out the distal end 210 of first needle 205 . suture holder 250 is configured so that the suture holder will carry the leading portion 245 l of suture 245 through loop 230 of snare 225 when the suture holder is extended out of first needle 205 . then suture holder 250 is withdrawn , leaving the leading portion 245 l of suture 245 extending though loop 230 of snare 225 ( fig2 ). next , leading portion 245 l of suture 245 is carried back to the near side of the meniscus . more particularly , and looking now at fig2 - 29 , snare 225 is retracted back into second needle 215 , second needle 215 is withdrawn back through the meniscus , and then first needle 205 is withdrawn back through the meniscus . thus , at this point in the procedure , suture 245 will have been passed from the near side of the meniscus , through the meniscus and then back again . significantly , by appropriately positioning first needle 205 and second needle 215 during the suture passing operation , suture 245 will extend across tear 20 formed in meniscus 5 . next , the suture is tied down so as to close the tear in the meniscus . this may be done in a variety of ways which will be apparent to those skilled in the art in view of the present disclosure . however , in one preferred form of the invention , the trailing portion 245 t of suture 245 may be arranged in the form of a pre - formed , uncinched knot 260 disposed about the exterior of second needle 215 ( see , for example , fig2 ) so that when snare 225 and second needle 215 carry leading portion 245 l of suture 245 back through the meniscus , they will also carry leading portion 245 l of suture 245 back through pre - formed , uncinched knot 260 ( fig2 ), which is formed by trailing portion 245 t of suture 245 . it will be appreciated that , as second needle 215 is withdrawn , pre - formed , uncinched knot 260 will slip off the end of second needle 215 , into direct contact with leading portion 245 l of suture 245 , as the suture passes back through itself . then , and looking now at fig3 , trailing portion 245 t of suture 245 is pulled taut so as to simultaneously ( i ) pull tear 20 closed , and ( ii ) tighten pre - formed knot 260 onto the suture , whereby to fix the suture in position and thereby close tear 20 in meniscus 5 . the trailing end 245 t of suture 245 can then be trimmed away in ways well known in the art , thereby leaving a low - profile suture fixation within the meniscus . looking now at fig3 - 35 , there is shown an apparatus 300 for use in closing tear 20 in meniscus 5 . apparatus 300 generally comprises a suture passer 301 ( fig3 - 33 ), a suture cartridge 302 ( fig3 ) and a knot pusher / cutter 303 ( fig3 ). specific details of the construction and function of suture passer 301 , suture cartridge 302 and knot pusher / cutter 303 will be disclosed in the course of the following discussion of using apparatus 300 to close tear 20 in meniscus 5 . looking now at fig3 - 33 , 36 and 37 , suture passer 301 , with suture cartridge 302 mounted thereon , is first manipulated so that its first needle 305 and its second needle 315 are advanced so that their distal tips 310 , 320 are passed completely through meniscus 5 . next , as seen as fig3 - 39 , a suture holder 350 carrying a suture 345 is advanced out distal end 310 of first needle 305 . suture holder 350 is configured so that the suture holder will carry the leading portion 345 l of suture 345 through a slot 330 of second needle 315 when the suture holder is extended out of first needle 305 . then , as shown in fig4 and 41 , an ejector wire 351 is used to eject leading portion 345 l of suture 345 from suture holder 350 . at this point , suture holder 350 is withdrawn , leaving leading portion 345 l of suture 345 extending though slot 330 of second needle 315 . see fig4 and 43 . then an obturator 352 is advanced within second needle 315 so as to pin leading portion 345 l of suture 345 to second needle 315 . next , suture passer 301 is retracted so that its first needle 305 and second needle 315 are withdrawn from the meniscus . see fig4 and 45 . thus , at this point in the procedure , suture 345 will have been passed from the near side of the meniscus , through the meniscus and then back again . significantly , by appropriately positioning first needle 305 and second needle 315 during the suture passing operation , suture 345 will extend across tear 20 formed in meniscus 5 . next , the suture is tied down so as to close the tear in the meniscus . this may be done in a variety of ways which will be apparent to those skilled in the art in view of the present disclosure . in one preferred form of the invention , this is accomplished in the following way . first , as shown in fig4 , suture cartridge 302 is dismounted from suture passer 301 . then suture cartridge 302 is mounted to knot pusher / cutter 303 ( fig4 ) and locked in place ( fig4 ). at this point , and looking now at fig4 and 50 , suture cartridge 302 is ready to receive leading portion 345 l of suture 345 . next , leading portion 345 l of suture 345 is inserted into a loop 353 of a snare basket 354 , as shown in fig5 - 53 . snare basket 354 essentially comprises a conventional suture threader component , or needle threader component , in the sense that a collapsible loop is formed at the end of a pullable tab . then snare basket 354 is retracted , carrying leading portion 345 l of suture 345 through a pre - formed , uncinched knot 360 formed in the trailing portion 345 t of suture 345 and disposed at the tip of knot pusher / cutter 303 . see fig5 - 56 . it will be appreciated that as snare basket 354 carries leading portion 345 l of suture 345 through pre - formed , uncinched knot 360 , the suture passes back through itself . then , and looking now at fig5 - 59 , knot pusher / cutter 303 is advanced distally so as to bring pre - formed , un - cinched knot 360 to the near side surface of the meniscus . next , as shown in fig6 and 61 , pre - formed , un - cinched knot 360 is tightened . then leading portion 345 l of suture 345 is trimmed away by knot pusher / cutter 303 ( fig6 and 63 ). finally , knot pusher / cutter 303 is removed , leaving suture 345 closing the tear in the meniscus ( fig6 and 65 ) with a low - profile suture fixation . in one preferred form of the invention , and looking now at fig6 , knot pusher / cutter 303 comprises a shaft s having a central bore b , a counterbore cb and a side opening so . a hollow ram r , having a ram side opening rso , is slidably disposed within bore b of shaft s . prior to knot deployment , the pre - formed , uncinched knot 360 is seated within counterbore cb ; and after leading portion 345 l of suture 345 is passed through pre - formed , uncinched knot 360 , leading portion 345 l is drawn through ram side opening rso and shaft side opening so ; and when the knot is to be separated from shaft s , ram r is moved distally , first pushing the knot out of the shaft and , after cinching , thereafter cutting leading portion 345 l of suture 345 by virtue of moving side opening so out of alignment with ram side opening rso . in one preferred form of the invention , the cinched knot is separated from shaft s in a first discrete step , and then the suture is cut in a second discrete step . looking now at fig6 , there is shown an apparatus 400 for use in closing tear 20 in meniscus 5 . apparatus 400 generally comprises a handle 401 , a needle cartridge 402 and a pusher / cutter 403 . pusher / cutter 403 is similar to suture cartridge 302 discussed above , in the sense that it carries a pre - formed , uncinched knot , etc ., as will hereinafter be discussed . specific details of the construction and function of handle 401 , needle cartridge 402 and pusher / cutter 403 will be disclosed in the course of the following discussion of using apparatus 400 to close tear 20 in meniscus 5 . looking now at fig6 and 68 , apparatus 400 is manipulated so that its first needle 405 and its second needle 415 are advanced so that their distal tips 410 , 420 are passed completely through meniscus 5 . next , as seen as fig6 and 70 , a suture holder 450 carrying a suture 445 is advanced out distal end 410 of first needle 405 . suture holder 450 is configured so that the suture holder will carry the leading portion 445 l of suture 445 through a slot 430 of second needle 415 when the suture holder is extended out of first needle 405 . then , as shown in fig7 and 72 , an ejector wire 451 is used to eject leading portion 445 l of suture 445 from suture holder 450 . at this point , suture holder 450 is withdrawn , leaving leading portion 445 l of suture 445 extending though slot 430 of second needle 415 . see fig7 and 74 . then an obturator 452 is advanced within second needle 415 so as to pin leading portion 445 l of suture 445 to second needle 415 . next , handle 401 is retracted so that its first needle 405 and second needle 415 are withdrawn from the meniscus . see fig7 . thus , at this point in the procedure , suture 445 will have been passed from the near side of the meniscus , through the meniscus and then back again . significantly , by appropriately positioning first needle 405 and second needle 415 during the suture passing operation , suture 445 will extend across tear 20 formed in meniscus 5 . next , the suture is tied down so as to close the tear in the meniscus . this may be done in a variety of ways which will be apparent to those skilled in the art in view of the present disclosure . in one preferred form of the invention , this is accomplished in the following way . looking now at fig7 and 77 , pusher / cutter 403 is ready to receive leading portion 445 l of suture 445 . then , as shown in fig7 - 81 , leading portion 445 l of suture 445 is inserted into a loop 453 of pusher / cutter 403 . again , loop 453 of pusher / cutter 403 essentially comprises a conventional suture threader component , or needle threader component , in the sense that a collapsible loop is formed at the end of a pullable shaft . then pusher / cutter 403 is detached from handle 401 , carrying leading portion 445 l of suture 445 . next , leading portion 445 l of suture 445 is passed through a pre - formed , uncinched knot 460 disposed at the tip of pusher / cutter 403 ( fig8 - 84 ). it will be appreciated that as leading portion 445 l of suture 445 is passed through pre - formed , uncinched knot 460 , the suture passes back through itself . then , and looking now at fig8 and 86 , pusher / cutter 403 is advanced distally so as to bring pre - formed , un - cinched knot 460 to the near side surface of the meniscus . next , as shown in fig8 - 89 , the pre - formed knot is tightened . then leading portion 445 l of suture 445 is trimmed away by pusher / cutter 403 ( fig9 and 91 ). finally , pusher / cutter 403 is removed , leaving suture 445 closing the tear in the meniscus with a low - profile suture fixation . in one preferred form of the invention , and looking now at fig8 , pusher / cutter 403 comprises a shaft s having a central bore b , a counterbore cb and a side opening so . a hollow ram r , having a ram side opening rso , is slidably disposed within bore b of shaft s . prior to knot deployment , the pre - formed , uncinched knot 460 is seated within counterbore cb ; and after leading portion 445 l of suture 445 is passed through pre - formed , uncinched knot 460 , leading portion 445 l is drawn through ram side opening rso and shaft side opening so ; and when the knot is to be separated from shaft s , ram r is moved distally , first pushing the knot out of the shaft and , after cinching , thereafter cutting leading portion 445 l of suture 445 by virtue of moving side opening so out of alignment with ram side opening rso . in one preferred form of the invention , the cinched knot is separated from shaft s in a first discrete step , and then the suture is cut in a second discrete step . in yet another preferred form of the present invention , the pre - formed , uncinched knot can be stored in a disposable tip that is releasably mounted to the needles , with the needles themselves being releasably mounted to the handle , and with the disposable tip being connectable to a pusher after the suture has been passed through the tissue . this construction has the advantage that ( i ) a single handle can be used for both the needles and pusher , and ( ii ) a single handle and a single pusher can be provided even where a patient may require multiple stitches ( i . e ., multiple disposable tips with multiple pre - formed , uncinched knots ). more particularly , and looking now at fig9 - 97 , there is shown an apparatus 500 for use in closing tear 20 in meniscus 5 . apparatus 500 generally comprises a handle 501 , a needle cartridge 502 , and a pusher 503 . needle cartridge 502 includes a disposable tip 504 which contains the pre - formed , uncinched knot 560 . specific details of the construction and function of handle 501 , needle cartridge 502 , pusher 503 and disposable tip 504 will be disclosed in the course of the following discussion of using apparatus 500 to close tear 20 in meniscus 5 . the apparatus 500 is prepared for use by mounting needle cartridge 502 mounted to handle 501 , and mounting pusher 503 to handle 501 ( fig9 ). apparatus 500 utilizes the same suture passing approach as apparatus 400 in order to pass and retract the leading portion of the suture from the near side of the meniscus to the far side of the meniscus and then back . once the leading portion 545 l of suture 545 is retracted to the near side of the meniscus , leading portion 545 l of suture 545 is threaded into loop 553 of a snare 554 . snare 554 in turn extends through the body of disposable tip 504 , including through pre - formed , uncinched knot 560 , and exits disposable tip 504 before being attached to needle cartridge 502 at 555 . then , pusher 503 is detached from handle 501 ( fig9 ) and is brought down into engagement with disposable tip 504 ( fig1 - 102 ). pusher 503 is then withdrawn , carrying disposable tip 504 with it . as disposable tip 504 is withdrawn from needle cartridge 502 , snare 554 is pulled back through the retreating disposable tip 504 thereby threading suture 545 l through pre - formed , uncinched knot 560 . thereafter , suture 545 is secured in the manner previously discussed . it will be appreciated that needles 105 , 115 , 205 , 215 , 305 , 315 , 405 , 415 , etc . may be straight ( as shown ) or curved as desired . furthermore , the apparatus 100 , 200 , 300 , 400 , 500 may be used with either a medial or lateral approach . it is to be understood that the present invention is by no means limited to the particular constructions herein disclosed and / or shown in the drawings , but also comprises any modifications or equivalents within the scope of the invention .
