Abstract

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.

Claims

1. A cardiovascular prosthetic valve, the valve comprising:

a cuff having a distal end and a proximal end;

an inflatable structure coupled to the cuff and having at least one inflatable channel that forms a toroidal structure; and

a valve 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;

wherein the distal end of the cuff has a non-circular cross-section with respect to the flow;

the non-circular cross-section configured to affect the performance of an adjacent valve.

2. A cardiovascular prosthetic valve, the valve comprising:

a flexible cuff having a distal end and a proximal end;

an inflatable structure coupled to the cuff and having at least one inflatable channel that forms a toroidal structure;

a valve mounted 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; and

at least anchor that is moveable between a first position in which the anchor extends in a radial direction to engage an adjacent anatomical structure and a second position in which the anchor has a reduced radial profile.

3. A cardiovascular prosthetic valve, the valve comprising:

an inflatable body;

a valve coupled to the body;

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; and

at least two control wires that are detachably coupled to the inflatable body.

4. The prosthetic valve as in claim 3, wherein each control wire comprises an outer sleeve and an inner elongated member moveably positioned within the outer sleeve, the outer sleeve including at least one opening through which a portion of the inflatable body extends, the inner elongated member moveable from a first position in which the inflatable body is locked within the at least one opening and a second position in which the inflatable body is disengaged from the second opening.

5. A cardiovascular prosthetic valve, the valve comprising:

an inflatable body comprising at least one inflation channel;

a valve coupled to the body;

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;

an inflation port in communication with the at least one inflatable channel;

a plug positioned within the inflation port;

an inflation tube extending through the inflation tube in communication with the at least one inflation channel; and

a balloon coupled to the inflation tube, the balloon configured to expand between a first, inflated position in which the balloon prevents the inflation tube from decoupling from the inflatiori port and a second, deflated position in which the inflation tube can be decoupled from the inflation port.
