Prosthetic valve devices and methods of making such devices
First Claim
1. A prosthetic valve device for implantation in a body vessel, comprising:
- a tubular main body having first and second ends and defining a lumen;
a prosthetic valve disposed at the second end, the valve adapted to permit fluid flow through the lumen in a first direction and substantially prevent fluid flow through the lumen in a second, opposite direction;
a support structure having proximal and distal ends, the proximal end disposed in the lumen of the main body, the second end of the main body and prosthetic valve disposed at that second end are inverted into the lumen such that the main body second end envelops the proximal end of the support; and
wherein the valve extends distal the support structure distal end.

Abstract
Prosthetic valve devices for implantation in body vessels, and methods of making same, are provided. The device has a main body with first and second ends and defining a lumen, with the second end being inverted into the lumen. A valve is disposed at the second end. In multiple valve devices, valves are disposed at the first and second ends, and individually may be inverted into the lumen. The prosthetic valve devices may further include a support structure such as a stent. Methods of making a prosthetic valve device include providing a main body having first and second ends and defining a lumen, forming a valve at the second end, and inverting the second end into the lumen. Methods may further comprise forming multiple valves and may also include attaching a support structure.
