Claims14
A device for preventing or mitigating paravalvular leakage associated with a valve replacement procedure, the device comprising:
- a first ring;
- a second ring that is axially spaced apart from the first ring;
- at least one pad section extending between the first and second rings;
- and
- a plurality of centering wires attached to at least one of the first and second rings.
A device for preventing or mitigating paravalvular leakage associated with an aortic valve replacement procedure, the device comprising:
- a first ring;
- a second ring that is axially spaced apart from the first ring;
- three pad sections extending between the first and second rings, each of the pad sections having a commissure engaging surface;
- a plurality of centering wires attached to at least one of the first and second rings.
A method for preventing or mitigating paravalvular leakage during a procedure to replace a diseased heart valve having a valve annulus and at least two commissures, the method comprising the steps of:
- providing a device that includes a first ring, a second ring that is axially spaced apart from the first ring, at least one pad section extending between the first and second rings, and a plurality of centering wires attached to at least one of the first and second rings;
- deploying the device in the valve annulus so that the at least one pad section engages at least one commissure to form a seal therebetween and thereby reduce or prevent paravalvular leakage;
- and
- deploying a prosthetic valve within the device.
