Abstract

A valve holder for a prosthetic valve having a stent with a stent base and multiple commissure posts projecting from the stent base, the valve holder including a central base portion, a plurality of legs radially extending from the central base portion, each leg comprising a first prong portion spaced from a second prong portion by a gap distance, a plurality of commissure post engaging members, wherein one commissure post engaging member is slideably engaged with each of the plurality of legs, and a handle extending from the central base portion.

Claims

1. A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder comprising:

a central base portion;

a plurality of legs radially extending from the central base portion, each leg comprising a first prong portion spaced from a second prong portion by a gap distance, wherein the first and second prong portions are flexible toward one another as facilitated by the gap distance, and wherein each of the first and second prong portions comprises a tab portion extending from a distal end thereof;

a plurality of commissure post engaging members, wherein one commissure post engaging member is slideably engaged with each of the plurality of legs so as to permit movement of the commissure post engaging member along the leg between a plurality of set positions, and wherein each of the commissure post engaging members comprises a first pair of apertures that are engageable with the tab portions of the first and second prong portions to position each of the commissure post engaging members in a first position; and

a handle extending from the central base portion.

2. The valve holder of claim 1, wherein each of the commissure post engaging members further comprises a second pair of apertures that are engageable with the tab portions of the first and second prong portions to position each of the commissure post engaging members in a second position, wherein the second position of the commissure post engaging members is closer to the central base portion than the first position of the commissure post engaging members.

3. A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder comprising:

a central base portion;

a plurality of legs radially extending from the central base portion, each leg comprising a first prong portion spaced from a second prong portion by a gap distance, wherein the first and second prong portions are flexible toward one another as facilitated by the gap distance;

a plurality of commissure post engaging members, each of which comprises a horizontal channel portion that slideably engages with one of the plurality of legs and a vertical portion extending from the horizontal channel portion, wherein one commissure post engaging member is slideably engaged with each of the plurality of legs so as to permit movement of the commissure post engaging member along the leg between a plurality of set positions; and

a handle extending from the central base portion;

wherein the vertical portion of each commissure post engaging member comprises an arcuate surface and multiple suture apertures spaced from each other.

4. The valve holder of claim 3, wherein the arcuate surface of the vertical portion comprises a first suture aperture spaced from and aligned relative to a second suture aperture so that a single needle can simultaneously pass through both the first and second suture apertures.

5. A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder comprising:

a central base portion;

a plurality of legs radially extending from the central base portion, each leg comprising a first prong portion spaced from a second prong portion by a gap distance, wherein the first and second prong portions are flexible relative to each other;

a plurality of commissure post engaging members, wherein one commissure post engaging member is slideably engaged with each of the plurality of legs and wherein each commissure post engaging member comprises a horizontal channel portion that slideably engages with one of the plurality of legs and a vertical portion extending from the horizontal channel portion, the vertical portion comprising an arcuate surface and multiple suture apertures spaced from each other; and

a handle extending from the central base portion.
