Abstract
Abstract An assembly for holding a substantially flexible suture guide of predetermined length in a substantially taut position used to achieve a suture line having a dimension equal to the length of the suture guide, such as the circumference about a heart valve annulus. The assembly includes a rigid suture guide holder having a surface against which the length of suture guide is releasably positioned. The guide holder can have a shape or geometry, such as a circumference or circumferential segment, equivalent to the shape or geometry of the intended suture line. The shape of the guide holder can therefore be selected to hold the suture guide in the shape most advantageous to placing the desired suture line. The assembly further includes a mechanism for releasably binding the suture guide to the surface of the holder and a detachable handle extendibly attached to the holder by means of a lanyard so that the handle can be detached to afford an unobstructed view of the surgical site, but cannot be removed from the surgical site until the holder has also been removed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
95 words
A suture guide and holder assembly comprising: a substantially flexible suture guide of predetermined length having a suturable covering; a rigid body defining a shaped surface against which the suture guide is releasably positioned along said predetermined length; releasable retaining means for tautly and releasably retaining the suture guide against the shaped surface; a handle detachably coupled to the body; and a spool of a length of filamentous material secured at one end to the body and at an opposite end to the handle wherein the spool is housed within a cavity in the handle.
Claim 2
Dependent Claim
95 words
A suture guide and holder assembly comprising: a substantially flexible suture guide of predetermined length having a suturable covering; a rigid body defining a shaped surface against which the suture guide is releasably positioned along said predetermined length; releasable retaining means for tautly and releasably retaining the suture guide against the shaped surface; a handle detachably coupled to the body; and a spool of a length of filamentous material secured at one end to the body and at an opposite end to the handle wherein the spool is housed within a cavity in the handle.
Claim 3
Dependent Claim
10 words
The assembly of claim 1 wherein the body is C-shaped.
Claim 4
Dependent Claim
33 words
The assembly of claim 1 wherein the shape of the body is lenticular and wherein the suture guide is positioned along the portion of the lenticular surface having the largest radius of curvature.
Claim 5
Dependent Claim
140 words
The assembly of claim 1 wherein the holder comprises a C-shaped body formed with an outwardly facing surface against which the suture guide is releasably affixed by the retaining means, said surface including one or more depressions for receiving a portion of the suture guide, and wherein the releasable retaining means includes at least a first thread affixed at both ends to the holder with a first portion passing at least partially through the suture guide, with the ends of the thread being affixed to the holder to expose a second portion of said thread that, when cut in two, subdivides said thread into two pieces, each affixed at one end to the holder, with at least one of the pieces defining the first portion being freely withdrawable from the suture guide to release the suture guide from the holder.
Claim 6
Dependent Claim
22 words
The suture guide and holder assembly of claim 1 wherein said suture guide comprises a flexible rib encased within the suturable covering.
Claim 7
Dependent Claim
95 words
A suture guide and holder assembly comprising: a substantially flexible suture guide of predetermined length having a suturable covering; a rigid body defining a shaped surface against which the suture guide is releasably positioned along said predetermined length; releasable retaining means for tautly and releasably retaining the suture guide against the shaped surface; a handle detachably coupled to the body; and means for tethering the handle to the body; wherein the retaining means comprises at least one filamentous strand that selectively stitches together respective ends of the suture guide and is attached to the body.
Claim 8
Dependent Claim
95 words
A suture guide and holder assembly comprising: a substantially flexible suture guide of predetermined length having a suturable covering; a rigid body defining a shaped surface against which the suture guide is releasably positioned along said predetermined length; releasable retaining means for tautly and releasably retaining the suture guide against the shaped surface; a handle detachably coupled to the body; and means for tethering the handle to the body; wherein the retaining means comprises at least one filamentous strand that selectively stitches together respective ends of the suture guide and is attached to the body.
Claim 9
Dependent Claim
30 words

Claim 10
Dependent Claim
10 words
The assembly of claim 6 wherein the body is C-shaped.
Claim 11
Dependent Claim
33 words
The assembly of claim 6 wherein the shape of the body is lenticular and wherein the suture guide is positioned along the portion of the lenticular surface having the largest radius of curvature.
