EXPANDABLE STENT WITH SLIDING AND LOCKING RADIAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a lumen support stent with a clear through-lumen for use in a body lumen.

SOLUTION: The stent is formed from at least one series of sliding and locking radial elements and at least one ratcheting mechanism comprising an articulating element and a plurality of stops. The ratcheting mechanism permits one-way sliding of the radial elements from a collapsed diameter to an expanded diameter, but inhibits radial recoil from the expanded diameter.
