Prosthetic valve support structure
The present invention is directed to prostheses including a support structure having a proximal end and a distal end, and a motion limiting member attached to the distal end of the support structure, wherein the motion limiting member is configured to restrict radial expansion of the distal end of the support structure. Methods for delivering the prosthesis are also provided.
1. A prosthesis comprising:
a support structure having an inflow section and an outflow section; and
a motion limiting member coupled to the outflow section of the support structure,
wherein radial motion of the outflow section is decoupled from radial interference at the inflow section by the motion limiting member.
2. The prosthesis of claim 1 , wherein the deployed diameter of the inflow section is variable, and
wherein the deployed diameter of the outflow section is constant at any deployed inflow section diameter.
