Flexible balloon-expanded stent for small vessels. Work in progress.
A new type of flexible, balloon-expanded, stainless steel stent was designed for introduction into small vessels subject to motion. Four stents placed in four dogs were patent at follow-up (4-8 weeks). A fibrocellular proliferation involving the intima and media was responsible for a 20%-25% luminal narrowing observed in all vessels with stents. The stent has longitudinal flexibility, which should permit its insertion into small peripheral, visceral, and coronary arteries.
