  • Implanting a cinching cord into a cardiac valve annulus
    Patent number: 9517130
    Abstract: An apparatus for cinching an anatomic passage (e.g., the annulus of the mitral valve or another cardiac valve) includes a cinching cord, slotted anchors, and corresponding sliding members disposed in the slots of the anchors. The sliding members are held captive within the slots by a protrusion on one side of the slot and by the presence of the cinching cord in apertures of the sliding members on the other side of the slot, because the cinching cord passes through the aperture in each of the sliding members. In some embodiments, at least one sleeve of material that accepts tissue ingrowth is disposed over the cinching cord. A closed loop of cord may also be used in place of the cinching cord in alternative embodiments, so that subsequent to implantation, the closed loop of cord prevents the anatomic annulus from expanding.

  • Flipping-type graft fixation device and method
    Patent number: 9456892
    Abstract: A buckle useful for cortical fixation has a graft retention loop slidably affixed thereto for movement from a first position adjacent a first end of the buckle to a second position at about the midpoint of the buckle. The buckle, with a graft over the loop, is drawn up lengthwise through a bone tunnel through a tibia and then flipped sideways to rest against the surface of the bone with the loop and graft depending back into the tunnel. The sliding attachment of the loop permits flipping of the buckle minimizes the flipping distance, which is the excess amount of the loop which must be pulled free of the tunnel to allow the buckle to be flipped sideways.
