IMPLANTABLE VALVE PROSTHESIS
First Claim
1. An implantable valve prosthesis (10) comprising a deformable body (12) having a first configuration that permits fluid flow communication in one direction while a second configuration prevents fluid communication in an opposite direction. The deformable body (12) defines a generally cylindrical configuration with a downstream opening in communication with an opposing upstream opening such that when the deformable body (12) is in the first configuration the downstream opening has substantially the same shape as the upstream opening, and when the deformable body (12) is in the second configuration the downstream opening has a smaller shape than the upstream opening, thereby preventing fluid flow communication in the opposite direction.

Abstract
An implantable valve prosthesis (10) having a deformable body (12) defining an upstream opening in fluid communication with a downstream opening wherein the deformable body (12) has a first configuration that permits fluid flow in one direction only and a second configuration that prevents retrograde fluid flow in the opposite direction is disclosed.

13. An implantable valve prosthesis (10) may include a deformable body (12) having a first position for permitting fluid flow communication inside a lumen in one direction only and a second position for preventing fluid flow communication inside the lumen in the opposite direction, the deformable body (12) being adapted to engage an expandable stent.

14. A method for deploying an implantable valve prosthesis (10) may include the steps of:
-
providing a catheter (40) defining a proximal end and a distal end;
attaching the distal end of the catheter (40) to an implantable valve prosthesis (10) having a deformable body (12) having a first configuration that permits fluid flow communication in one direction while a second configuration prevents fluid communication in an opposite direction with the deformable body (12) defining a generally cylindrical configuration with a downstream opening in communication with an opposing upstream opening such that when the deformable body (12) is in the first configuration the downstream opening has substantially the same shape as the upstream opening, and when the deformable body (12) is in the second configuration the downstream opening has a smaller shape than the upstream opening, thereby preventing fluid flow communication in the opposite direction; and
implanting the distal end of the catheter (40) inside the lumen of a body such that the implantable valve prosthesis (10) is disposed across the lumen of the body in a manner that permits selective fluid flow communication through the lumen by the deformable body of the implantable valve prosthesis (10).
