Valve device with inflatable chamber
First Claim
1. A method of implanting a valve in a body vessel having a vessel wall, the method comprising the steps of:
- delivering said valve to a point of treatment within said body vessel using a deployment apparatus, said valve comprising at least one flexible member and an inflatable chamber, the at least one flexible member movable between a first position that permits fluid flow in a first direction and a second position that substantially prevents fluid flow in a second direction, the at least one flexible member at least partially attached to the inflatable chamber and having an outer edge, the inflatable chamber comprising a first portion extending along the outer edge of the at least one flexible member and a second portion extending from a first location on the outer edge, across the at least one flexible member, and to a second location on the outer edge, the inflatable chamber adapted to receive inflating media and to engage the body vessel;
inflating the first portion of the inflatable chamber with inflating media;
inflating the second portion of the inflatable chamber with inflating media, the second portion of the inflatable chamber being filled separately from the first portion of the inflatable chamber;
detaching said valve from the deployment apparatus; and
removing the deployment apparatus from said body vessel.

Abstract
Prosthetic valve devices for implantation in body vessels are provided. The prosthetic valve device includes at least one flexible member that permits fluid flow in a first direction and substantially prevents fluid flow in a second. The valve device also includes an inflatable chamber at least partially attached to the flexible member. The inflatable chamber is adapted to receive inflating media and is adapted to contact the body vessel. A delivery system is also provided that includes a valve device and a delivery apparatus. The delivery apparatus includes a member adapted for filling the chamber of the valve device with inflating media. A related method of making the valve device is also provided.
