  • Patent number: 5776187
    Abstract: The invention relates to a holder/rotator device which may be used to hold and then rotate a heart valve prosthesis during implantation of the heart valve prosthesis. The device comprises holder/rotator which includes a post and a rotator head, and a handle. The rotator head comprises a gripping surface of a material which engages and grips the surface of the heart valve prosthesis and facilitates the smooth rotation of the valve.

  • Patent number: 5735842
    Abstract: A manipulable low profile heart valve holder that can be pivotally attached to a handle that permits the heart valve holder and a retained heart valve prosthesis to be manipulated remotely during implantation. The heart valve holder is pivotable from a position wherein the plane of the orifice of a retained heart valve is parallel to the axis of the handle, to a second position wherein the plane of the retained heart valve is substantially 90.degree. to the axis of the handle. This pivoting arrangement particularly aids in manipulation of the heart valve prosthesis during implantation using trocars for access to the body cavity. Manipulation is accomplished by having controllable elements on the handle and retained on the exterior of the patient. Manipulation of the heart valve holder also may be done through separate instruments operating through separate trocars.

  • Patent number: 5571175
    Abstract: An artificial heart valve prosthesis for use in a heart includes an orifice defining a lumen therethrough for blood flow. An occluder is carried in the orifice and is movable between an open position which allows blood flow through the lumen and a closed position in which flow through the lumen is blocked. A suture cuff coupled to the orifice extends around an outer circumference of the orifice and is used for attaching the heart valve to a heart tissue annulus using sutures. The sutures are knotted proximate the suture cuff to secure the cuff to the annulus. A suture guard is coupled to the suture cuff and is movable between an open position in which the suture knot is exposed and a closed position in which the suture, suture knot and suture cuff are covered.
