Claims
- 1. A prosthetic valve comprising:
a radially expandable structural frame having a plurality of distal crowns, the structural frame being formed from a lattice of interconnected elements, and having a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between; a tubular biocompatible membrane coaxially disposed over at least a portion of the structural frame such that the structural frame supports the biocompatible membrane assembly in a slack condition between the distal crowns.
- 2. The prosthetic valve of claim 1 wherein the structural frame further comprises a valve strut attached to at least one of the distal crowns and extending in a distal direction substantially parallel to the longitudinal axis.
- 3. The prosthetic valve of claim 1 wherein the distal crowns are articulating.
- 4. The prosthetic valve of claim 1 wherein the biocompatible membrane assembly extends in a distal direction past the distal crowns.
- 5. A prosthetic valve comprising:
a radially expandable structural frame having a plurality of distal crowns, the structural frame being formed from a lattice of interconnected elements, and having a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between; a tubular biocompatible membrane coaxially disposed over at least a portion of the structural frame such that the structural frame supports the biocompatible membrane assembly in a flexible condition between the distal crowns.
- 6. A prosthetic valve comprising:
a substantially cylindrical structural frame having a hoop structure, the hoop structure having a plurality of distal crowns; a substantially cylindrical biocompatible membrane assembly coaxially disposed over the structural frame such that the structural frame supports the biocompatible membrane assembly in a slack condition between the distal crowns.
- 7. A prosthetic valve having a radially expandable structural frame comprising:
a cylindrical hoop structure having a plurality of distal and proximal crowns; a proximal anchor formed from a lattice of interconnected elements and having a substantially cylindrical configurations; one or more connecting members, the one or more connecting members having a first and a second end, the first end of each connecting member being attached to the proximal anchor and the second end of each connecting member being attached to the hoop structure; and a substantially cylindrical biocompatible membrane assembly attached to the proximal anchor and extending distally along the one or more connecting members to the distal crowns, such that the distal crowns.
