MITRAL VALVE IMPLANTS
Implants and methods for treating diseased heart valves. The implants may include a support member configured for placement near the diseased valve and an anchoring system coupled to the support member. The support member may be used to treat regurgitation and/or support a valve replacement therein. The support member may have an annular shape with an opening configured to generally align with an opening of the diseased valve. In some examples, the support member includes a coaptation structure configured to seal with the native leaflets. The anchoring system may include one or more tethers anchored to tissue of a ventricle, such as a ventricle wall and/or a papillary muscle. In some examples, sufficient tension is applied on the tethers to stabilize or reduce ventricle dilation.
1 . A system for treating a diseased heart, the system comprising:
an annular support member that is shaped and sized for placement near a native valve annulus;
an anchor member comprising at least one anchor portion configured for implantation in tissue within a ventricle; and
at least one tether that is configured for extension from the at least one anchor portion to the support member, the at least one tether configured to apply a tensioning force between the support member and the at least one anchor portion.
2 . The system of claim 1 , wherein the at least one anchor portion is configured for implantation in a ventricle wall or a papillary muscle.
3 . The system of claim 1 , wherein the support member is configured to alter a dimension of the native valve annulus.
4 . The system of claim 1 , wherein the at least one tether is configured to secure the support member to the native valve annulus.
5 . The system of claim 1 , wherein the at least one anchor portion comprises a coil near a distal end thereof.
6 . The system of claim 1 , wherein the at least one anchor portion comprises a taper that reduces to a point at a distal end thereof.
7 . The system of claim 1 , wherein the at least one anchor portion includes an elongate tube having a first circumference, and wherein the at least one anchor portion comprises an expandable region configured to expand to a second circumference that is larger than the first circumference, wherein the expandable region is near a distal end of the at least one anchor portion.
8 . The system of claim 7 , wherein the at least one anchor portion comprises at least two expandable regions configured to expand to circumferences larger than the first circumference.
9 . The system of claim 1 , wherein the support member comprises a self-expanding material.
10 . The system of claim 1 , further comprising a prosthetic valve that is sized and shaped to be placed within the support member.
11 . The system of claim 10 , wherein the prosthetic valve is configured to transition from an unexpanded configuration to an expanded configuration.
12 . The system of claim 10 wherein, upon placement within the support member, the prosthetic valve is configured to displace native valve leaflets.
13 . The system of claim 1 , further comprising first and second flow meters that are coupled with the support member, and that are positioned and configured for inductive coupling.
14 . The system of claim 13 , wherein the first and second flow meters are disposed about a periphery of the support member.
15 . The system of claim 1 , wherein the annular support member is expandable and includes wires arranged to form an annular shape.
16 . The system of claim 15 , wherein the wires define an inner wall and outer wall.
17 . The system of claim 1 , wherein the annular support member is conically shaped.
18 . The system of claim 1 , wherein the annular support member is half-dome shaped.
19 . The system of claim 1 , wherein the at least one anchor includes an expandable portion that is configured to expand from a first diameter to a second diameter.
20 . The system of claim 1 , wherein the at least one anchor includes a collapsible tube having a pattern of cutouts that is configured to collapse the tube and form radially extending arms.
