Methods for venous valve replacement with a catheter
First Claim
Patent Images
1. A method, comprising:
- forming a valve that includes;
a valve frame;
a valve leaflet joined to the valve frame, wherein the valve leaflet includes surfaces defining a reversibly sealable opening extending between a first region and a second region for unidirectional flow of a liquid; and
a support frame, where the support frame meets the valve frame at the first region and the second region on an axis that extends parallel with the reversibly sealable opening of the valve leaflet, and where the valve frame and the support frame extend from the axis in an opposing direction; and
reversibly joining the valve and a catheter.

Abstract
A venous valve apparatus, system and method for valve replacement. The valve includes a valve frame, a valve leaflet joined to the valve frame, and a support frame. The valve leaflet includes surfaces defining a reversibly sealable opening for unidirectional flow of a liquid. The support frame meets the valve frame on an axis, where the valve frame and the support frame extend from the axis in an opposing direction. The system further includes a catheter, where the valve can be reversibly joined to the catheter at a location between a proximal end and a distal end of the catheter. The system can be used to deploy the valve from the catheter at a predetermined location.

10. A method, comprising:
-
positioning at least part of a catheter including a valve at a predetermined location, wherein the valve includes; a valve frame; a valve leaflet joined to the valve frame, wherein the valve leaflet includes surfaces defining a reversibly sealable opening extending between a first region and a second region for unidirectional flow of a liquid; and a support frame, where the support frame meets the valve frame at the first region and the second region on an axis that is coextensive with the reversibly sealable opening of the valve leaflet, and where the valve frame and the support frame extend from the axis in an opposing direction; and deploying the valve from the catheter at the predetermined location. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
