Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
93 words
A suturing implement particularly useful in surgical operations for suturing a member, such as a prosthetic valve, to tissue at the suture site by a plurality of sutures each including a needle attached to at least one end thereof, comprising: a manually grippable handle; pledget gripping means carried by said handle for gripping a plurality of pledgets each in a position to be pierced by a suture needle; and releasing means carried by said handle for actuating said pledget gripping means to release said pledgets and the sutures applied thereto from said handle.
Claim 2
Dependent Claim
93 words
A suturing implement particularly useful in surgical operations for suturing a member, such as a prosthetic valve, to tissue at the suture site by a plurality of sutures each including a needle attached to at least one end thereof, comprising: a manually grippable handle; pledget gripping means carried by said handle for gripping a plurality of pledgets each in a position to be pierced by a suture needle; and releasing means carried by said handle for actuating said pledget gripping means to release said pledgets and the sutures applied thereto from said handle.
Claim 3
Dependent Claim
28 words
The suturing implement according to claim 1, wherein said pledget gripping means grips said plurality of pledgets while in the form of an annular array around said handle.
Claim 4
Dependent Claim
58 words
The suturing implement according to claim 2, wherein said pledget gripping means comprises a pair of annular members adapted to receive between them said annular array of pledgets, one of said annular members being movable by said releasing means toward and away from the other annular member to grip and to release, respectively , said plurality of pledgets.
Claim 5
Dependent Claim
26 words
The implement according to claim 3, wherein said pair of annular members comprise axially-extending grooves for guiding the suture needle when applied to pierce the pledgets.
Claim 6
Dependent Claim
24 words
The implement according to claim 1, further including suture retaining means for releasably retaining a plurality of sutures in folded condition on said handle.
Claim 7
Dependent Claim
42 words
The implement according to claim 5, wherein said suture retaining means retains said plurality of sutures in the form of an annular array on said handle with the sutures spaced circumferentially from each other and folded axially with respect to said handle.
Claim 8
Dependent Claim
44 words
The implement according to claim 6, wherein said suture retaining means comprises a plurality of circumferentially-spaced strips each extending axially of the handle and formed with a pair of radially-extending resilient arms at its opposite ends for retaining the sutures in said folded condition.
Claim 9
Dependent Claim
30 words
The implement according to claim 7, wherein said strips are of resilient material and include intermediate portions integrally formed with said arms and received in axially-extending grooves in said handle.
Claim 10
Dependent Claim
29 words
The implement according to claim 8, wherein said suture retaining strips are secured by outer cover plates fixed to said handle to overly said intermediate portions of said strips.
Claim 11
Dependent Claim
39 words
The implement according to claim 6, wherein said suture retaining means further comprises an annular ring secured to said handle and formed with an annular array of slots for receiving the suture needles at the ends of the sutures.
Claim 12
Dependent Claim
24 words
The implement according to claim 1, further including a holder at one end of the handle for releasably holding the member to be sutured.
Claim 13
