Abstract

A disposable clip which finds application in the temporary occlusion of blood vessels, bowels, ducts, and so forth, consumes a small volume within an operative field during use, and may be removed without the need for highly specialized tools. In terms of construction, a pair of substantially rigid, spaced-apart members are joined by way of a malleable hinge. Each member includes an inwardly oriented surface which oppose and face one another and outwardly oriented surfaces which face away from one another. A layer of compressible material is supported against the inwardly oriented surface of each member and, with an externally applied pressure exerted upon the outwardly oriented surfaces, the pair of rigid members are urged toward one another, thereby compressing and at least temporarily occluding the vessel between the layers of compressible material, with the malleable hinge maintaining the clip in this configuration until removal. Means are further provided enabling the members and layers of compressible material to separate from one another through the application of an externally applied removal force.

Claims

1. A disposable clip for temporarily occluding a vessel, comprising:

a pair of substantially rigid, spaced-apart members, each having first and second ends, the first ends of the two members being joined through a malleable hinge, each member further including an inwardly oriented surface which faces the inwardly oriented surface of the other and outwardly oriented surfaces which face away from one another;

a layer of compressible material supported against the inwardly oriented surface of each member;

the distance between the inwardly oriented surfaces, including the layers of compressible material, being sufficient to a at least partially surround a vessel to be temporarily occluded therebetween,

the clip having a first state wherein the vessel is at least partially surrounded, and a second state wherein an externally applied pressure is exerted upon the outwardly oriented surfaces, urging the members toward one another, thereby compressing and at least temporarily occluding the vessel between the layers of compressible material, with the malleable hinge maintaining the clip in its second state until removal; and

means enabling the members and layers of compressible material to separate from one another through the application of an externally applied removal force.

2. The disposable clip of claim 1, wherein the members are generally parallel to one another in the first state.

3. The disposable clip of claim 1, wherein the members assume a V-shaped appearance in the first state.

4. The disposable clip of claim 1, wherein the means enabling the members and layers of compressible material to separate from one another includes a break-away bond therebetween.

5. The disposable clip of claim 1, wherein the means enabling the members and layers of compressible material to separate from one another includes a track feature between the inwardly oriented surfaces of each members and the layers of compressible material, enabling the members and layers of compressible material to be pulled in opposite directions to effectuate their separation.
