A new Coronary Stent using thermal shape memory Ti/Ni alloy was developed to prevent restenosis following PTCA. 10 Coronary Stents (ID 3mm length 5mm, thickness 0.15mm) were implanted in 10 rabbits in the abdominal aorta. A Coronary Stent was patent upto 1 month. 22 Stents (ID 5mm length 5mm thickness 0.25-0.4mm) were implanted in 11 dogs to evaluate biocompatibility. 21/22 stents were patent upto 2 years.
