Low profile manipulators for heart valve prostheses
First Claim
1. A low profile heart valve holder assembly comprising:
- a valve holder body sized for fitting within and supporting a heart valve orifice ring, said heart valve holder defining a plane and having a generally disk-like shape within said plane;
a handle; and
a pivot connection between the handle and the valve holder body permitting pivoting movement of substantially 90°
of the valve holder body between first and second positions while supporting a heart valve orifice ring.

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° 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.

13. A low profile heart valve holder and handle assembly comprising a heart valve holder adapted to retain a heart valve orifice ring thereon, said heart valve holder defining a plane and having a generally disk-like shape within said plane;
-
a handle for manipulating the heart valve holder and having a longitudinal axis; a hinge connection for hingedly coupling the handle to the heart valve holder, said hinge connection permitting movement of the heart valve holder about an axis substantially parallel to the plane of the heart valve holder and perpendicular to the longitudinal axis, and permitting movement of the heart valve holder from a position with said plane of the heart valve holder substantially parallel to the longitudinal axis, to a second position with said plane of the heart valve holder substantially 90°
to the longitudinal axis with a heart valve orifice ring supported on the heart valve holder;the hinge connection being substantially within the periphery of the heart valve holder. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
