Kathleen L. Hess has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Controlled deployment of a medical device
    Patent number: 6872223
    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.
    Type: Grant
    Filed: October 1, 2001
    Date of Patent: March 29, 2005
    Assignee: Boston Scientific Corporation

  • Medical stents for body lumens exhibiting peristaltic motion
    Patent number: 6305436
    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.
