Mitral valve prosthesis rotator
First Claim
1. A surgical rotator for orienting a prosthetic mechanical heart valve in a mitral valve having an annular valve body with a central orifice therethrough, said rotator comprising,a handle having a distal end, a proximal end and a length extending therebetween, symmetrical about an axismeans for engaging said heart valve, said means for engaging said heart valve being generally symmetrical about an axis, andmeans for connecting said proximal end of said handle and said means for engaging said heart valve with said axis of said handle lying generally parallel to said axis of said means for engaging said heart valve, and said axis of said handle being eccentrically offset from said axis of said means for engaging, said means for engaging and said means for connecting having a combined proximal-to-distal length small enough to fit within a thoracic cavity of a patient.

Abstract
A prosthetic heart valve rotator with an eccentric socket attached to a bendable shaft. The heart valve is manipulated by a rotator head which is attached to the socket in any of a plurality of selectable angular positions. The rotator head is held in the socket by a spring which circumscribes the socket, thereby reducing stress in the spring.

10. A rotator for orienting a prosthetic heart valve comprising
a handle, and means for engaging said heart valve, said means for engaging said heart valve comprising connector means attached to said handle having first mating means thereon, a rotator head for engaging said heart valve and having thereon a congruent second mating means configured to engage said first mating means, and a spring circumferentially disposed about said first mating means and releasably engaging said second mating means for releasably attaching said rotator head to said connector means.

11. A rotator for orienting a prosthetic mechanical heart valve comprising an annular valve body with a central orifice therethrough, said rotator comprising,
a handle having a distal end, a proximal end and a length extending therebetween, a rotator head for engaging said heart valve, said rotator head having a post thereon, and means for connecting said proximal end of said handle and said rotator head, said means for connecting having a junction where said proximal end of said handle joins said means for connecting, an eccentric socket in said means for connecting, said socket being offset perpendicularly to said length of said handle away from said junction and being configured to receive said post, and a spring circumferentially disposed about said socket for releasably engaging said post on at least one side thereof.
-
19. A rotator for a prosthetic heart valve comprising
a handle symmetrical about an axis, a rotator head for engaging said heart valve, and means attached to said handle for releasably connecting said rotator head in a selected one of at least three radially distinct originations about an axis, said axis of said rotator head being generally parallel to said axis of said handle and spaced a distance away from said axis of said handle, said distance being perpendicular to said axis of said handle.
