Abstract
Abstract An improved retainer for surgical sutures is provided which includes a suture retaining compartment comprising a suture winding panel with the panel having a pair of holding panels foldably connected to longitudinal edges of the suture winding panel. The holding panels are foldably connected to the winding panel by at least three gussets formed at the edges of the suture winindg panel. The gussets at the ends of the foldable connection prevent frictional compression of the wound suture at the corners of the retaining compartment, and the central gussets or gussets engender a convex curvature to the holding panels, thereby creating a low friction volumetric compartment which retains the suture in place. The suture retainer also includes a needle holding means mounted at the intended location of the needle. In illustred embodiments of the present invention the holding means is angularly disposed with respect to the longitudinal dimension of the retainer to afford ease of needle withdrawal, and in some embodiments the holding means is located on a foldable needle park panel. In some embodiments the retainer includes an insert against which the suture is wound. This insert provides several features, including preventing snagging of the suture on the needle holding means during suture withdrawal, and protection of the needle point. The insert may also include a flap to prevent the suture from snagging on a corner of the insert during withdrawal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
An improved retainer for surgical sutures which encloses a surgical suture, and including a compartment in which said suture is retained, comprising: a first panel having a longitudinal edge; and a second panel foldably connected to said longitudinal edge of said first panel, the foldable connection of said second panel to said edge of said first panel including, at each end of said foldable connection, a gusset comprising two transversely separated score lines extending inwardly from said end and terminating in a single score line, and said foldable connection further comprising an additional gusset located between said end gussets, said additional gusset comprising two transversely separated score lines terminating in a single score line at each end of said additional gusset.
Claim 2
Dependent Claim
121 words
An improved retainer for surgical sutures which encloses a surgical suture, and including a compartment in which said suture is retained, comprising: a first panel having a longitudinal edge; and a second panel foldably connected to said longitudinal edge of said first panel, the foldable connection of said second panel to said edge of said first panel including, at each end of said foldable connection, a gusset comprising two transversely separated score lines extending inwardly from said end and terminating in a single score line, and said foldable connection further comprising an additional gusset located between said end gussets, said additional gusset comprising two transversely separated score lines terminating in a single score line at each end of said additional gusset.
Claim 3
Dependent Claim
162 words
An improved retainer for surgical sutures which encloses a surgical suture, and including a compartment in which said suture is retained, comprising: a suture winding panel having a pair of longitudinal edges and a pair of transverse edges; a pair of suture holding panels foldably connected to said longitudinal edges of said suture winding panel, each foldable connection of a suture holding panel to an edge of said suture winding panel including, at each end of said foldable connection, a gusset comprising two parallel score lines extending inwardly from said end and terminating in a single score line, whereby, when said suture holding panels are folded over said suture winding panel, a suture retaining compartment is defined therebetween exhibiting volumetric regions at the corners of said compartment, wherein each foldable connection further comprises an additional gusset located between said end gussets, said additional gusset comprising two parallel score lines terminating in a single score line at each end of said additional gusset.
Claim 4
Dependent Claim
162 words
An improved retainer for surgical sutures which encloses a surgical suture, and including a compartment in which said suture is retained, comprising: a suture winding panel having a pair of longitudinal edges and a pair of transverse edges; a pair of suture holding panels foldably connected to said longitudinal edges of said suture winding panel, each foldable connection of a suture holding panel to an edge of said suture winding panel including, at each end of said foldable connection, a gusset comprising two parallel score lines extending inwardly from said end and terminating in a single score line, whereby, when said suture holding panels are folded over said suture winding panel, a suture retaining compartment is defined therebetween exhibiting volumetric regions at the corners of said compartment, wherein each foldable connection further comprises an additional gusset located between said end gussets, said additional gusset comprising two parallel score lines terminating in a single score line at each end of said additional gusset.
Claim 5
Dependent Claim
30 words
The improved retainer of claim 2, wherein said additional gusset imparts a convex curvature to said folded holding panels defining a volumetric region in the central portion of said compartment.
Claim 6
Dependent Claim
92 words
The improved retainer of claim 2, further comprising a suture enclosing panel having two longitudinal edges and two transverse edges, said enclosing panel being foldably connected at one of its transverse edges to a transverse edge of said suture winding panel, and a pair of retainer interlocking panels, an edge of one of said retainer interlocking panels being foldably connected to a longitudinal edge of said suture enclosing panel and an edge of the other said retainer interlocking panel being foldably connected to the opposite longitudinal edge of said suture enclosing panel.
Claim 7
Dependent Claim
28 words
The improved retainer of claim 4, wherein each foldable connection of said suture enclosing panel to said suture winding panel and said retainer interlocking panels comprises a gusset.
Claim 8
Dependent Claim
31 words
The improved retainer of claim 5, wherein each of said gussets of said suture enclosing panel connections comprises two parallel score lines terminating at their ends at a single score line.
