Prosthetic valve
First Claim
1. A prosthetic valve for implantation in a body site, the valve comprising:
- 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 having a proximal portion and a distal portion; and
a receptacle operatively connected to the proximal portion of the at least one flexible member, the receptacle having an expanded position adapted to receive fluid flowing in the second direction and a contracted position adapted to allow fluid flow through the valve in the first direction, and an attachment portion operably connected to the receptacle for attaching the valve to the body site.

Abstract
Prosthetic valves and a method for making a prosthetic valve for implantation in a body site are provided. The prosthetic valve includes 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 flexible member has a proximal portion and a distal portion. The valve includes a receptacle operatively connected to the proximal portion of flexible member. The receptacle has an expanded position adapted to receive fluid flowing in the second direction and a contracted position adapted to allow fluid flow through the valve in the first direction. The valve further includes an attachment portion operably connected to the receptacle for attaching the valve to the body site.

12. A prosthetic valve for implantation in a body site, the valve comprising:
-
a flexible member and a receptacle together moveable between an open configuration permitting fluid flow in a first direction and a closed configuration substantially preventing fluid flow in a second direction; and
an attachment portion operably connected to the receptacle for attaching the valve to the body site;
wherein the flexible member and the receptacle comprise a biocompatible material and are integrally formed. - View Dependent Claims (13, 14, 15)

16. A method of making a prosthetic valve device for implantation in a body site, the method comprising:
-
forming a flexible member, the flexible member being 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;
forming a receptacle having an expanded position for receiving fluid flow in the second direction and a contracted position for allowing fluid flow in the first direction through an opening in the valve;
providing an attachment portion operably connected to the receptacle for implanting the valve in the body site; and
assembling the valve for implantation into the body site. - View Dependent Claims (17, 18, 19, 20)
