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 providing controlled delivery of therapeutic agents to a vessel wall. The prosthesis comprises a helical body having a plurality of turns, wherein the proximal and distal edges of the turns of the prosthesis has a pattern that interdigitates when the prosthesis assumes the deployed configuration. The prosthesis optionally may comprise a radially expanding distal portion coupled to the helical body for facilitating placement of the prosthesis within a body vessel.
Claims20
A vascular prosthesis for implantation in a body vessel, the vascular prosthesis comprising:
- a helical section comprising a plurality of cells defining a plurality of turns, each turn having a distal edge and a proximal edge, the helical section configured to transition between a contracted delivery configuration, in which adjacent turns are wound down onto one another, and a deployed configuration,
- wherein cells disposed along the distal edge define a series of crests, cells disposed along the proximal edge define a series of complimentary troughs, and in the deployed configuration the series of crests interdigitate with the series of troughs.
