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 directly 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 the second end of the cantilever valve strut being free to deflect in at least a radial direction from the longitudinal axis; 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.

33. A prosthetic valve comprising:
-
a radially expandable anchor structure formed from a lattice of interconnected elements, and having a substantially cylindrical configuration with a first and a second open end and a longitudinal axis defining a longitudinal direction extending there between; a collar located proximal to the radially expandable anchor; a connecting member having a first and a second end, the first end of the connecting member being directly attached to the second end of the anchor and the second end of the connecting member being directly attached to the proximal collar; a cantilever valve strut having a first and a second end, the first end of the cantilever valve strut being attached to the proximal collar and the second end of the cantilever valve strut being free to deflect in at least a radial direction from the longitudinal axis, the cantilever valve strut extending in a distal direction substantially parallel to the longitudinal axis; and
a biocompatible membrane assembly having a substantially tubular configuration with a first open and a second closed end, the first end of the membrane assembly being attached to thecantilever valve strut along the second end of the cantilever valve strut.
