Abstract
Official abstract text for this publication.
A venous valve with a frame and a cover on the frame for unidirectional flow of a liquid through the valve.
First claim
Opening claim text (preview).
What is claimed is: 1. A valve, comprising: a frame having a first leaflet connection region, a second leaflet connection region, and a longitudinal axis; 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, wherein each of the integrated flexible support members are circumferentially disposed about the longitudinal axis and support the first leaflet and the second leaflet; wherein the second material of the integrated flexible support members includes spun-fibers of a ceramic. 2. The valve of claim 1 , wherein the ceramic includes basalt. 3. A valve, comprising: a frame having a first leaflet connection region, a second leaflet connection region, and a longitudinal axis; 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, wherein each of the integrated flexible support members are circumferentially disposed about the longitudinal axis and support the first leaflet and the second leaflet; wherein the integrated flexible support members are in a configuration selected from the group consisting of woven, matted, coiled, rings, braided and knitted. 4. A system, comprising: a valve, wherein the valve includes: a frame having a first leaflet connection region, a second leaflet connection region, and a longitudinal axis; 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, wherein each of the integrated flexible support members are circumferentially disposed about the longitudinal axis and support the first leaflet and the second leaflet; and a catheter including a proximal end and a distal end, the valve located between the proximal end and distal end of the catheter; wherein the first leaflet and the second leaflet are formed of a first material and the integrated flexible support members are formed of a second material; wherein the second material of the integrated flexible support members includes spun-fibers of a ceramic. 5. A system, comprising: a valve, wherein the valve includes: a frame having a first leaflet connection region, a second leaflet connection region, and a longitudinal axis; 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, wherein each of the integrated flexible support members are circumferentially disposed about the longitudinal axis and support the first leaflet and the second leaflet; and a catheter including a proximal end and a distal end, the valve located between the proximal end and distal end of the catheter; wherein the integrated flexible support members are in a configuration selected from the group consisting of woven, matted, coiled, rings, braided and knitted.
