Abstract

Claims (18)

1 . An implant configured to control travel of a leaflet of a heart valve, the implant comprising:

a first implant member that includes:

a first mechanical tissue fastener;

a second mechanical tissue fastener;

a first implant member connector; and

an adjustable length tether connecting the first mechanical tissue fastener disposed at a first end portion of the tether and the second mechanical tissue fastener disposed along a second end portion of the tether, and the first implant member connector; and

a second implant member that includes:

a magnetic second implant member connector; and

a tissue anchor;

wherein the first implant member connector and the second implant member connector are magnetically couplable; and

wherein the second mechanical tissue fastener slideably displaceable along the second portion of the adjustable length tether; wherein the second portion of the adjustable length tether includes a plurality of fixed, spaced-apart, locking elements to maintain the second mechanical tissue fastener at a fixed location on the second portion of the adjustable length tether; wherein the first implant member connector further includes an through-hole to accommodate passage of the adjustable length tether through the second implant member connector, such that the first implant member connector is disposed at a location along the adjustable length tether between the first mechanical tissue fastener and the a second mechanical tissue fastener.

2 . The implant of claim 1 wherein the locking elements include elastically deformable locking elements, the elastically deformable locking elements to deform to pass through the through-hole.

3 . The implant of claim 1 wherein the first implant member connector includes a magnetic first implant member connector.

4 . The implant of claim 1 wherein the first implant member connector includes one or more magnetic materials.

5 . The implant of claim 1 wherein the magnetic second implant member connector includes a rare earth magnetic material.

6 . The implant of claim 1 wherein the second implant member further includes a shape memory alloy anchor.

7 . The implant of claim 6 wherein the shape memory alloy anchor includes a central receiver portion to receive the tissue anchor and a plurality of shape memory alloy hook members.

8 . The implant of claim 1 wherein the tissue anchor comprises a helical tissue anchor.
