BALLOON EXPANDABLE BIOABSORBABLE DRUG ELUTING STENT

摘要

A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stent (1000) has a plurality of hoop components (1002) interconnected by a plurality of flexible connectors (1004). The hoop components are formed as a continuous series of substantially longitudinally or axially oriented radial strut members (1006) and alternating substantially circumferentially oriented radial arc members (1008). The geometry of the struts and arcs is such that when the stent is expanded, it has very high strains within a relatively small region (1020). This strain localization results in what is often referred to as "hinging", where the hinge is the small region within which the strains are very high.
