Abstract
A venous valve with a frame and a cover on the frame for unidirectional flow of a liquid through the valve.
Claims37
A valve, comprising:
- a frame having a first leaflet connection region and a second leaflet connection region;
- a first leaflet coupled to the first leaflet connection region and the second leaflet connection region;
- and
- a second leaflet coupled to the first leaflet connection region and the second leaflet connection region, wherein the first leaflet and the second leaflet have integrated flexible support members to provide support to the first leaflet and the second leaflet, the first leaflet connection region and the second leaflet connection region having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve.

A system, comprising:
- a valve, wherein the valve includes:
- a frame having a first leaflet connection region and a second leaflet connection region;
- a first leaflet coupled to the first leaflet connection region and the second leaflet connection region;
- a second leaflet coupled to the first leaflet connection region and the second leaflet connection region, wherein the first leaflet and the second leaflet have integrated flexible support members to provide support to the first leaflet and the second leaflet, the first leaflet connection region and the second leaflet connection region having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve;
- and
- a catheter including a proximal end and a distal end, the valve located between the proximal end and distal end of the catheter.
3 more elements
A method, comprising:
- forming a frame having leaflet connection regions;
- forming a first leaflet and a second leaflet having integrated flexible support members to provide support to the first leaflet and the second leaflet;
- coupling the first leaflet and the second leaflet to the leaflet connection regions of the frame to form a valve having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve;
- and
- reversibly joining the valve and a catheter.
2 more elements
A method, comprising:
- positioning at least part of a catheter including a venous valve at a predetermined location, wherein the venous valve includes:
- a frame having a first leaflet connection region and a second leaflet connection region;
- a first leaflet coupled to the first leaflet connection region and the second leaflet connection region;
- a second leaflet coupled to the first leaflet connection region and the second leaflet connection region, wherein the first leaflet and the second leaflet have integrated flexible support members to provide support to the first leaflet and the second leaflet, the first leaflet connection region and the second leaflet connection region having surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve;
- and
- deploying the venous valve from the catheter at the predetermined location.
