LOCKING STENT HAVING MULTIPLE LOCKING POINTS

摘要

A stent includes a lattice of interconnecting elements defining a substantially cylindrical configuration having a first open end and a second open end. The lattice has a closed configuration and an open configuration. The lattice includes a plurality of adjacent hoops, wherein at least two hoops are movable to one or more discrete locked positions as the open configuration and at least one hoop interlocks with another hoop at the one or more discrete locked positions. Moreover, the stent can be made from a biodegradable or bioabsorbable material.
