First Claim
Patent Images
1. A method of delivering and deploying a tubular construct into a body lumen to open occlusions or to provide flow therein, comprising the steps of:
- a) inserting a tubular construct comprising a flexible and axially collapsible bellows of a diameter sufficiently less than that of said lumen when axially uncompressed, and greater when axially compressed, into said lumen;
b) advancing said construct through said lumen and around any bends therein to a desired site of deployment; and
c) axially compressing at least the bellows of said construct until said bellows achieves a diameter approximately equal to that of said lumen site, so as to be retained at said lumen site.

Abstract
A medical construct particularly useful as a stent, comprising an axially compressible bellows of a material and dimensions sufficient to provide negligible resistance to flexure transverse to the axis and negligible recoil under compression or expansion along the axis, and apparatus and a method for deploying the same.
