Development of coronary stents. WALLSTENTÂ® (Schneider AG), a self-expanding, stainless steel wire-mesh structure, was the first coronary stent implanted in a human coronary artery by Sigwart et al. in 1986.
Have had two stents for stones. While the stent may be unconfortable, passing of the stones is painless down to the bladder. Placing of a stent is painless as anesthesia is used, removal of a stent is a very quick procedure which should be done under anesthesia. Have had litho twice, stones still in kidney but smaller.
