US Patent:

6872223, Mar 29, 2005

Filed:

Oct 1, 2001

Appl. No.:

09/968149

Inventors:

George T. Roberts - Weston MA, US
Kathleen L. Hess - Lynn MA, US
Sepideh H. Nott - Fall River MA, US
Michael S. H. Chu - Brookline MA, US
Yem Chin - Burlington MA, US

Assignee:

Boston Scientific Corporation - Natick MA

International Classification:

A61F002/06

US Classification:

623 111

Abstract:

A prosthesis delivery system having a balloon catheter with an inflatable balloon on its exterior. The balloon is inflatable by injection of fluid through a lumen in the catheter and the balloon is initially partially constrained against inflation by a constraint. A tubular prosthesis is disposed on the catheter over at least a portion of the balloon and a portion of the constraint. The tubular prosthesis has a contracted condition and an expanded condition. The tubular prosthesis is initially disposed on the catheter in the contracted condition. Further, a balloon catheter includes a constraint so that the balloon may be sequentially inflated for dilatation purposes such as in a valvuloplasty operation.

Appl. No.:

8/756456

Inventors:

Erik Andersen - Roskilde, DK

Kathleen L. Hess - Lynn MA
Susanne Urhoj - Charlottenlund, DK

Assignee:

Boston Scientific Corporation - Watertown MA

International Classification:

A61F 204
A61F 206

US Classification:

623 11

Abstract:

Methods for forming, shaping and heat treating stents for reinforcement of the lumen of peristaltic organs. The stent is formed by knitting preferably a nitinol wire into a pattern of overlapping loops selected such that from a relaxed state each row of loops may shift axially relative to and independently of the rows on either side. This local lengthening and shortening accommodates peristalsis of the organ without migrating within the organ.
