Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 225 words
A holder for holding a heart valve prosthesis during implantation in a patient, the heart valve having an annulus and at least one occluder carried therein moveable between an open position allowing flow through the annulus and a substantially closed position substantially blocking flow through the annulus, the holder comprising: a holder body generally conforming to the annulus of the heart valve prosthesis; an annular extension protruding from the holder body and adapted to protrude into the annulus of the heart valve prosthesis, at least a portion of the extension adapted to generally conform to a portion of an inner surface of the heart valve prosthesis; means coupled to the holder body for attaching the holder body to the heart valve prosthesis, wherein the means for attaching comprises an attachment suture; and an occluder engaging compliant member adjacent the holder body adapted to engage the occluder, the member positioned to contact the occluder when the holder body is attached to the heart valve prosthesis whereby the occluder is maintained in the substantially closed position and substantially protected by the annulus of the heart valve prosthesis, wherein the occluder engaging compliant member comprises an occluder engaging suture which is adapted to extend adjacent the annulus of the heart valve prosthesis and is adapted to contact the occluder to maintain the occluder in the substantially closed position.
Claim 2
Dependent Claim 225 words
A holder for holding a heart valve prosthesis during implantation in a patient, the heart valve having an annulus and at least one occluder carried therein moveable between an open position allowing flow through the annulus and a substantially closed position substantially blocking flow through the annulus, the holder comprising: a holder body generally conforming to the annulus of the heart valve prosthesis; an annular extension protruding from the holder body and adapted to protrude into the annulus of the heart valve prosthesis, at least a portion of the extension adapted to generally conform to a portion of an inner surface of the heart valve prosthesis; means coupled to the holder body for attaching the holder body to the heart valve prosthesis, wherein the means for attaching comprises an attachment suture; and an occluder engaging compliant member adjacent the holder body adapted to engage the occluder, the member positioned to contact the occluder when the holder body is attached to the heart valve prosthesis whereby the occluder is maintained in the substantially closed position and substantially protected by the annulus of the heart valve prosthesis, wherein the occluder engaging compliant member comprises an occluder engaging suture which is adapted to extend adjacent the annulus of the heart valve prosthesis and is adapted to contact the occluder to maintain the occluder in the substantially closed position.
Claim 3
Dependent Claim 14 words
The holder of claim 1 wherein the means for attaching comprises an attachment suture.
Claim 4
Dependent Claim 27 words
The holder of claim 1 wherein the engaging suture is adapted to couple the holder to the heart valve prosthesis and thereby provide the means for attaching.
Claim 5
Dependent Claim 25 words
The holder of claim 1 wherein the holder body includes a suture opening formed therein and the occluder engaging suture extends through the suture opening.
Claim 6
Dependent Claim 14 words
The holder of claim 4 wherein the suture is knotted within the holder body.
Claim 7
Dependent Claim 29 words
The holder of claim 5 wherein the knot attaches the suture to the holder body whereby the suture remains coupled to the holder body if the suture is severed.
Claim 8
Dependent Claim 56 words
The holder of claim 1 including an elevated suture tensioning extension extending in a direction away from the holder body, wherein the occluder engaging suture extends over the suture tensioning extension which provides tension on the suture to maintain the occluder in the closed position when the holder body is attached to the heart valve prosthesis.
Claim 9
Dependent Claim 26 words
The holder of claim 7 wherein the elevated suture extension includes a top surface having a suture guide formed therein for receiving the occluder engaging suture.
Claim 10
Dependent Claim 45 words
The holder of claim 1 wherein the heart valve prosthesis includes two occluders moveable between open and closed positions and the occluder engaging member is adapted to maintain both occluders in substantially closed positions when the holder body is attached to the heart valve prosthesis.
Claim 11
Dependent Claim 11 words
The holder of claim 1 including a second occluder engaging suture.
Claim 12
Dependent Claim 150 words
A holder for holding a heart valve prosthesis during implantation in a patient, the heart valve having an annulus and at least one occluder carried therein moveable between an open position allowing flow through the annulus and a substantially closed position substantially blocking flow through the annulus, the holder comprising: a holder body generally conforming to the annulus of the heart valve prosthesis; means coupled to the holder body for attaching the holder body to the heart valve prosthesis; and an occluder engaging suture adjacent the holder body adapted to engage the occluder, the suture extending across the holder body and adapted to be positioned in the annulus of the heart valve prosthesis to thereby contact the occluder when the holder body is attached to the heart valve prosthesis whereby the occluder is maintained in the substantially closed position and substantially protected by the annulus of the heart valve prosthesis.
Claim 13
Dependent Claim 150 words
A holder for holding a heart valve prosthesis during implantation in a patient, the heart valve having an annulus and at least one occluder carried therein moveable between an open position allowing flow through the annulus and a substantially closed position substantially blocking flow through the annulus, the holder comprising: a holder body generally conforming to the annulus of the heart valve prosthesis; means coupled to the holder body for attaching the holder body to the heart valve prosthesis; and an occluder engaging suture adjacent the holder body adapted to engage the occluder, the suture extending across the holder body and adapted to be positioned in the annulus of the heart valve prosthesis to thereby contact the occluder when the holder body is attached to the heart valve prosthesis whereby the occluder is maintained in the substantially closed position and substantially protected by the annulus of the heart valve prosthesis.
Claim 14
Dependent Claim 14 words
The holder of claim 11 wherein the means for attaching comprises an attachment suture.
Claim 15
Dependent Claim 27 words

The holder of claim 15 wherein the knot attaches the suture to the holder body whereby the suture remains coupled to the holder body if the suture is severed.
Claim 19
Dependent Claim 56 words
The holder of claim 11 including an elevated suture tensioning extension extending in a direction away from the holder body, wherein the occluder engaging suture extends over the suture tensioning extension which provides tension on the suture to maintain the occluder in the closed position when the holder body is attached to the heart valve prosthesis.
Claim 20
Dependent Claim 26 words
The holder of claim 17 wherein the elevated suture extension includes a top surface having a suture guide formed therein for receiving the occluder engaging suture.
Claim 21
Dependent Claim 45 words
The holder of claim 11 wherein the heart valve prosthesis includes two occluders moveable between open and closed positions and the occluder engaging suture is adapted to maintain both occluders in substantially closed positions when the holder body is attached to the heart valve prosthesis.
