Translumenally implantable heart valve with formed in place support
A cardiovascular prosthetic valve includes a cuff having a distal end and a proximal end. An inflatable structure is coupled to the cuff and has at least one inflatable channel that forms a toroidal structure. A valve is coupled to the cuff; the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction. In one arrangement, the distal end of the cuff has a non-circular cross-section with respect to the flow and the non-circular cross-section is configured to affect the performance of an adjacent valve. In another arrangement, the cuff includes an anchor moveable from a first position to a second position. In another arrangement, control wires are coupled to the cuff.
1. A stentless cardiovascular implant comprising:
a continuous, stentless, annular tubular body, movable from a collapsed tubular configuration for translumenal navigation to a patent tubular configuration having a central lumen for permitting blood flow therethrough following deployment;
a first inflatable annulus and a second inflatable annulus on the body;
a valve coupled to the tubular body; the valve configured to permit blood flow in a first axial direction through the central lumen and to inhibit blood flow in a second axial direction opposite to the first axial direction; and
at least two inflation tubes that are detachably coupled to the tubular body;
wherein introduction of inflation media into at least one of the first and second annulus holds the tubular body in the patent tubular configuration.
2. A stentless cardiovascular implant as in claim 1 , wherein the tubular body comprises a fabric sleeve.
3. A stentless cardiovascular implant as in claim 2 , wherein the fabric comprises Dacron®.
4. A stentless cardiovascular implant as in claim 2 , wherein the fabric comprises ePTFE.
5. A stentless cardiovascular implant as in claim 1 , wherein the first inflatable annulus is positioned at a first end of the implant and the second inflatable annulus is positioned at a second end of the implant.
6. A stentless cardiovascular implant as in claim 1 , further comprising inflatable struts positioned in between the first and second inflatable annulus.
7. A stentless cardiovascular implant as in claim 6 , wherein the inflatable struts are in fluid communication with one of the first and second inflatable annulus.
8. A stentless cardiovascular implant as in claim 6 , wherein at least one of the first and second inflatable annulus is separately inflatable from the inflatable struts.
9. A stentless cardiovascular implant as in claim 1 , wherein at least one of the first and second inflatable annulus is dimensioned to provide a seal to prevent blood from reentering the left ventricle.
10. A stentless cardiovascular implant as in claim 1 , wherein the implant has an outside diameter when in the patent tubular configuration within the range of from about 14 mm to about 30 mm.
11. A stentless cardiovascular implant as in claim 1 , further comprising three inflatable commissural supports.
12. A stentless cardiovascular implant as in claim 1 , wherein the valve comprises a plurality of tissue leaflets.
13. A stentless cardiovascular implant as in claim 12 , wherein the tissue comprises pericardium.
14. A stentless cardiovascular implant as in claim 1 , wherein the valve comprises polymer leaflets.
15. A stentless cardiovascular implant as in claim 13 , wherein the pericardium is decellularized.
16. A stentless cardiovascular implant as in claim 1 , comprising three control wires.
17. A stentless cardiovascular implant as in claim 16 , further comprising three control wire tubes.
18. A stentless cardiovascular implant as in claim 1 , further comprising a valve for retaining inflation media within the inflatable annulus following detachment of the inflation tube.
