发明名称 BALLON-EXPANDABLE, CRUSH-RESISTANT LOCKING STENT.
摘要 An intraluminal, crush resistant stent for implantation in a body lumen is disclosed. The crush resistant stent is made from a base section having a plurality of resilient, parallel, coplanar struts having a zig-zag configuration extending therefrom wherein the zig-zag struts are curved and pass through corresponding slots in the base section to form a continuous, cylindrical hoop. Each ziz-zag strut has an amplitude that decreases when the zig-zag strut is placed under tension and an amplitude that increases when the zig-zag strut is unstressed or is placed under compression. Accordingly, each zig-zag strut can be pulled through the respective slot in the base section, but under compression the zig-zag struts assume the larger amplitude and cannot pass through the corresponding slot thereby maintaining the diameter of the stent constant.
