Abstract
The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements. The individual radially expandable cylindrical elements consist of ribbon-like material disposed in an undulating pattern. Portions of the expanded stent project outwardly into engagement with the vessel wall to more securely attach the stent.
Claims13
A method of implanting a stent in a body lumen, comprising the steps of:
- (a) providing a stent;
- (b) mounting the stent on a balloon of a balloon catheter;
- (c) partially inflating the balloon to secure the stent onto the balloon;
- (d) advancing the catheter, including the balloon and stent, through the body lumen;
- (e) positioning the balloon and stent at a desired location in the body lumen;
- (f) expanding the balloon, thereby deploying the stent at the desired location;
- (g) deflating the balloon;
- and
- (h) removing the catheter from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
A method of implanting a stent in a body lumen, comprising the steps of:
- (a) providing a stent;
- (b) mounting the stent on an expandable member of a delivery catheter;
- (c) partially expanding the expandable member of the delivery catheter to secure the stent onto the expandable member;
- (d) advancing the catheter, including the expandable member and stent, through the body lumen;
- (e) positioning the expandable member and stent at a desired location in the body lumen;
- (f) expanding the expanding member, thereby deploying the stent at the desired location;
- (g) contracting the expandable member;
- and
- (h) removing the catheter and expandable member from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
