an apparatus and a method configured for the efficient delivery of a viscous material , such as bone cement , to a surgical site are described . a housing removably receives a large gauge syringe which is filled with the viscous material . the apparatus is a syringe - type assembly that uses at least one vibrating motor together with a plunger rod assembly . the method employs the continuous application of vibrational forces to the central barrel portion of the apparatus during the time that the viscous material is being delivered and / or applied in vivo . the vibration to the central barrel portion increases the tendency of the viscous material to flow thereby making delivery of such materials easier and more efficient .
