Abstract

Systems, devices and methods for heart valve prostheses are described. An implant is inserted proximate a mitral valve, and has a tubular body and a plurality of piercing members, the tubular body comprising an upper diameter and a lower diameter. Tissue proximate the mitral valve is engaged by the plurality of piercing members and the tubular body transitions from a first structural configuration to a second structural configuration by application of an expansive force to the tubular body proximate the upper diameter, the first structural configuration having the upper diameter smaller than the lower diameter and the second structural configuration having the upper diameter larger than the lower diameter.

Claims

1. A method comprising:

inserting an implant proximate a mitral valve, the implant comprising a tubular body and a plurality of piercing members, the tubular body comprising an upper diameter and a lower diameter;

engaging tissue proximate the mitral valve by the plurality of piercing members on a first side of the mitral valve from within the left atrium;

coupling at least one of the plurality of piercing members with a location ring that is positioned on a second side of the mitral valve within the left ventricle; and

transitioning the tubular body from a first structural configuration to a second structural configuration by application of an expansive force to the tubular body proximate the upper diameter, the first structural configuration having the upper diameter smaller than the lower diameter and the second structural configuration having the upper diameter larger than the lower diameter.

2. The method of claim 1, wherein the engaging tissue step further comprises applying vibration to at least one of the plurality of piercing members.

3. The method of claim 1, wherein the engaging tissue step further comprises applying vibration to the tissue proximate the mitral valve either on a same side of the mitral valve as the implant or on a side of the mitral valve opposite the implant.

4. The method of claim 1, wherein the transitioning the tubular body step further comprises applying an upward force on a fixed ring positioned within the tubular body, the fixed ring comprising a diameter larger than the upper diameter in the first structural configuration.

5. The method of claim 1, wherein the transitioning the tubular body further comprises:

placing an expandable ring proximate the upper diameter; and

expanding the expandable ring to increase the upper diameter.

6. The method of claim 1, wherein at least one of the plurality of piercing members is covered during the insertion of the implant proximate the mitral valve step.

7. The method of claim 1, wherein at least one of the plurality of piercing members engages the tissue proximate the mitral valve before another of the plurality of piercing members.
