Abstract

Abstract A package for a plurality of sterile, dry, hydrolyzable, surgical ligating clips. The package comprises a disposable means for holding the ligating clips in a spaced apart relationship. The clips are disposed in the holding means to provide an area around each clip for access thereto. The clips themselves have a pair of legs which are connected at their proximal ends by a narrowed resilient hinge portion. The hinge portion of the clip is more sensitive to hydrolysis than the remainder of the clip. The package also includes means, for example, pre dried paper for permanently removing moisture from the area around the clips. The disposable holding means, the clips, and the moisture removing means are wrapped by impermeable wrappers whereby the final package maintains the resiliency of the hinge portion of the clips over an extended shelf life period. Preferably, the clips are made from polymers of dioxanone although they may be made from other of the absorbable polymer materials such as the homopolymers of glycolide, and lactide or copolymers of the same, or copolymers of either with dioxanone.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 188 words
A package comprising: (a) disposable means for holding a plurality of ligating clips in spaced apart relationship to facilitate dispensing of a clip: (b) a plurality of sterile, dry, hydrolyzable surgical ligating clips disposed in spaced apart relationship in said disposable holding means, each of said clips having a narrowed resilient hinge portion, said hinge portions being more sensitive to hydrolysis than the remainder of said clip; (c) absorbing means adjacent to said holding means, said absorbing means having a greater affinity for moisture than any portion of said clip whereby any moisture present in said package, including moisture in the area around each clip, is preferentially absorbed by said absorbing means, said absorbing means having sufficient absorbent capacity to maintain the clips dry and sterile while in the unopened package; (d) and a moisture impermeable outer wrap disposed in sealing relationship with respect to the disposable holding means, clips, and moisture absorbing means, whereby said initially dry and sterile clips are maintained dry and sterile until the package is opened to maintain the resiliency of the hinge portion of the clips for an extended shelf life period.
Claim 2
Dependent Claim 188 words
A package comprising: (a) disposable means for holding a plurality of ligating clips in spaced apart relationship to facilitate dispensing of a clip: (b) a plurality of sterile, dry, hydrolyzable surgical ligating clips disposed in spaced apart relationship in said disposable holding means, each of said clips having a narrowed resilient hinge portion, said hinge portions being more sensitive to hydrolysis than the remainder of said clip; (c) absorbing means adjacent to said holding means, said absorbing means having a greater affinity for moisture than any portion of said clip whereby any moisture present in said package, including moisture in the area around each clip, is preferentially absorbed by said absorbing means, said absorbing means having sufficient absorbent capacity to maintain the clips dry and sterile while in the unopened package; (d) and a moisture impermeable outer wrap disposed in sealing relationship with respect to the disposable holding means, clips, and moisture absorbing means, whereby said initially dry and sterile clips are maintained dry and sterile until the package is opened to maintain the resiliency of the hinge portion of the clips for an extended shelf life period.
Claim 3
Dependent Claim 16 words
The package according to claim 1 wherein the clips are made from a polymer of p-dioxanone.
Claim 4
Dependent Claim 16 words
The package according to claim 1 wherein the clips are made from a polymer of glycolide.
Claim 5
Dependent Claim 16 words
The package according to claim 1 wherein the clips are made from a polymer of lactide.
Claim 6
Dependent Claim 21 words
The package according to claim 1 wherein the absorbing means adjacent the holding means for preferentially absorbing moisture comprises pre-dried paper.
