Vascular prosthesis 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 helical section comprising a plurality of helical turns and having distal and proximal ends;
a distal anchor section joined to the distal end, the distal anchor section forming a radially self-expanding anchor; and
a proximal anchor section joined to the proximal end, the proximal anchor section forming a radially self-expanding anchor.

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 one or more helical sections coupled to one or more anchoring sections 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 or foreshortening during deployment.
