Vascular prosthesis including torsional stabilizer and methods of use
First Claim
1. A vascular prosthesis for implantation in a body vessel having a vessel wall, the vascular prosthesis comprising:
- a proximal section comprising a plurality of helical turns and a distal end;
a distal section joined to the distal end, the distal section forming a self-expanding anchor; and
a torsional stabilizer coupled to the distal end of the proximal section.

Abstract
The present invention is directed to an implantable vascular prosthesis configured for use in a wide range of applications, such as treating aneurysms, maintaining patency in a vessel, and allowing for the controlled delivery of therapeutic agents to a vessel wall. The prosthesis comprises a helical proximal section coupled to a distal anchoring section having a generally zig-zag or cell-like configuration. The prosthesis is configured to conform to a vessel wall without substantially remodeling the vessel, and further is configured to be precisely deployed in a vessel without shifting during deployment. The prosthesis also has a substantially small delivery profile compared to other known stents, while having an increased surface area to enhance delivery of therapeutic agents.
