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.
