Abstract

A medical device includes a polymer stent (or scaffold) crimped to a catheter balloon. The stent, after being expanded from a crimped state by the balloon, provides a crush recovery of about 90% of its expanded diameter after being pinched or crushed by an amount equal to about 50% of the expanded diameter. The stent has a pattern including a W-shaped or W-V shaped closed cell and links connecting the closed cells.
