Abstract

A unit cell for use in a medical device, such as a stent, is disclosed along with a description of a stent formed from a plurality of unit cells and for use in the treatment of restenosis or other vascular narrowing. The unit cell is designed and configured for uniform radial expansion with minimal axial shortening and recoil, and is selectively variable in flexibility and expendability.
