Implantable valvular prosthesis
First Claim
1. A prosthetic valve comprising:
- a radially expandable structural frame defining a longitudinal axis, including an anchor structure having first and second open ends, a connecting member having first and second ends, the first end of the connecting member being attached to the second end of the anchor structure, and a cantilever valve strut having first and second ends, the first end of the cantilever valve strut being cooperatively associated with the second end of the connecting member; and
a biocompatible membrane assembly having a substantially tubular configuration about the longitudinal axis, with a first open and a second closed end, the first end of the membrane assembly being attached along the second end of the cantilever valve strut.

Abstract
The present invention relates to a medical device, and in particular, to a stent-based valve. The valve includes a radially expandable structural frame including an anchor structure having a first and a second open end, a connecting member having a first and a second end, and a cantilever valve strut having a first and a second end. The first end of the connecting member is attached to the second end of the anchor structure. The first end of the cantilever valve strut is cooperatively associated with the second end of the connecting member. The prosthetic valve further includes a biocompatible membrane assembly having a substantially tubular configuration about the longitudinal axis, with a first open and a second closed end. The first end of the membrane assembly is attached to the structural frame along the second end of the cantilever valve strut.
