Abstract

Abstract A prosthetic heart valve holder includes a set of jaws. Each jaw includes a distal end adapted for coupling to the prosthetic heart valve and a proximal end. A hinge assembly pivotally couples the jaws together between the distal and proximal ends. The hinge assembly allows movement of the jaws between an engaged position for grasping the prosthetic heart valve and an disengaged position in which the prosthetic heart valve is free from the distal ends. A locking collar is attached to the jaws and is movable between a first position in which the proximal ends are free from the collar, and a second position in which the collar holds the proximal ends of the jaws whereby the distal ends are held in position to engage the prosthetic heart valve.

Claims Analysis

Total Claims: 27
Claim 1
Independent Claim 194 words
A prosthetic heart valve holder for holding a prosthetic heart valve, the prosthetic heart valve holder comprising: a set of jaws, wherein each jaw includes a distal end adapted for coupling to the prosthetic heart valve and a proximal end; a hinge assembly pivotally coupling the jaws together between the distal and proximal ends and defining an axis of the holder wherein a jaw is positioned on each side of the axis and the axis extends from the proximal ends to the distal ends, the hinge assembly allowing movement of the jaws between an engaged position for grasping the prosthetic heart valve and a disengaged position in which the prosthetic heart valve is free from the distal ends; and a collar substantially rigid to maintain an aperture therethrough, the collar being movably attached to the jaws and slidable between a first position on the holder in which the proximal ends are free from the collar to pivot and a second position in which the proximal ends extend into the aperture and the collar holds the proximal ends of the jaws whereby the distal ends are held in position to engage the prosthetic heart valve.
Claim 2
Dependent Claim 194 words
A prosthetic heart valve holder for holding a prosthetic heart valve, the prosthetic heart valve holder comprising: a set of jaws, wherein each jaw includes a distal end adapted for coupling to the prosthetic heart valve and a proximal end; a hinge assembly pivotally coupling the jaws together between the distal and proximal ends and defining an axis of the holder wherein a jaw is positioned on each side of the axis and the axis extends from the proximal ends to the distal ends, the hinge assembly allowing movement of the jaws between an engaged position for grasping the prosthetic heart valve and a disengaged position in which the prosthetic heart valve is free from the distal ends; and a collar substantially rigid to maintain an aperture therethrough, the collar being movably attached to the jaws and slidable between a first position on the holder in which the proximal ends are free from the collar to pivot and a second position in which the proximal ends extend into the aperture and the collar holds the proximal ends of the jaws whereby the distal ends are held in position to engage the prosthetic heart valve.
Claim 3
Dependent Claim 16 words
The prosthetic heart valve holder of claim 1 wherein the collar is slidable on the jaws.
Claim 4
Dependent Claim 26 words
The prosthetic heart valve holder of claim 2 wherein the collar is slidable on the holder along a line non-parallel to the axis of the holder.
Claim 5
Dependent Claim 27 words
The prosthetic heart valve holder of claim 3 wherein the collar is slidable on the holder along a line substantially perpendicular to the axis of the holder.
Claim 6
Dependent Claim 30 words
The prosthetic heart valve holder of claim 4 wherein the collar includes at least one resilient member selectively engageable with one of the proximal ends of the set of jaws.
Claim 7
Dependent Claim 28 words
The prosthetic heart valve holder of claim 4 wherein the collar comprises a pair of resilient members selectively engageable with the proximal ends of the set of jaws.
Claim 8
Dependent Claim 21 words
The prosthetic heart valve holder of claim 2 wherein the collar is slidable substantially parallel to the axis of the holder.
Claim 9
Dependent Claim 19 words
The prosthetic heart valve holder of claim 7 wherein the collar is rotatable about the axis of the holder.
Claim 10
Dependent Claim 18 words
The prosthetic heart valve holder of claim 7 wherein the collar engages stop surfaces at the first position.
Claim 11
Dependent Claim 34 words
The prosthetic heart valve holder of claim 9 wherein a longitudinal length of a first portion of the collar is shorter than an adjacent portion of the collar to form a recessed stop surface.
Claim 12
Dependent Claim 34 words
The prosthetic heart valve holder of claim 2 wherein the collar includes a bore extending through the collar having a first opening on one end larger than a second opening on the other end.
Claim 13
Dependent Claim 35 words
The prosthetic heart valve holder of claim 2 wherein the collar includes a bore and a resilient member is secured to an inner surface of the collar about at least a portion of the bore.
Claim 14
Dependent Claim 32 words
The prosthetic heart valve holder of claim 1 wherein one of the jaws includes an extending portion, and wherein the locking collar is positioned on the extending portion in the first position.
Claim 15
Dependent Claim 66 words
The prosthetic heart valve holder of claim 1 and a stem having a proximal end and a distal end, and wherein the hinge assembly includes a first hinge formed between a first jaw of the set of jaws and the distal end of the stem, and a second hinge formed between a second jaw of the set of jaws and the distal end of the stem.
Claim 16
Dependent Claim 32 words
The prosthetic heart valve holder of claim 14 wherein the locking collar is slidable from the first position on the proximal end of the stem toward the distal end of the stem.
Claim 17
