Abstract
Abstract A heart valve holder is provided for holding a heart valve prothesis including an orifice ring having an aperture with a circumferential surface, comprising: a body having a longitudinal axis; a first lever section having a first insertion end and resiliently attached to the body along a first flexure region having a first flexure axis for selectively engaging the heart valve prosthesis; and a second lever section having a second insertion end and resiliently attached to the body along a second flexure region having a second flexure axis parallel to the first flexure axis for selectively engaging the heart valve prosthesis. The body and the first and second lever sections include receiving means for receiving a flexible tensile member to secure engagement of the first and second lever sections to the heart valve prosthesis by flexing the first and second flexure regions so that the first and second insertion ends abut the circumferential surface of the aperture.

133 words
A heart valve holder for holding a heart valve prosthesis including an orifice ring having an aperture with a circumferential surface, comprising: a body having a longitudinal axis; a first lever section having a first insertion end and resiliently attached to said body along a first flexure region having a first flexure axis for selectively engaging said heart valve prosthesis; a second lever section having a second insertion end and resiliently attached to said body along a second flexure region having a second flexure axis parallel to said first flexure axis for selectively engaging said heart valve prosthesis; and said body, and said first and second lever sections further including receiving means for receiving a flexible tensile member to secure engagement of said first and second lever sections to said heart valve prosthesis.
Claim 2
Dependent Claim
133 words
A heart valve holder for holding a heart valve prosthesis including an orifice ring having an aperture with a circumferential surface, comprising: a body having a longitudinal axis; a first lever section having a first insertion end and resiliently attached to said body along a first flexure region having a first flexure axis for selectively engaging said heart valve prosthesis; a second lever section having a second insertion end and resiliently attached to said body along a second flexure region having a second flexure axis parallel to said first flexure axis for selectively engaging said heart valve prosthesis; and said body, and said first and second lever sections further including receiving means for receiving a flexible tensile member to secure engagement of said first and second lever sections to said heart valve prosthesis.
Claim 3
Dependent Claim
37 words
The heart valve holder of claim 1 wherein: said first and second flexure axes are separated by a fixed distance centered about said longitudinal axis and define a plane perpendicular to said longitudinal axis of said body.
Claim 4
Dependent Claim
40 words
