Abstract
Abstract A hemostatic clip is in the form of a tubular body member having a longitudinal slit extending completely across the body for receiving a wound flap when the body is distended from its original shape. A pair of projections are on the body member joined to the body member along a longitudinal line disposed about 90* from the slit to act as convenient means for distending the body from its original shape when external force is aPplied to the projections.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
A hemostatic clip comprising a body in the form of an elongated tubular element, said tubular element having an ellipsoidal cross section, wound-flap-engaging means on said body, said wound-flap-engaging means being an elongated longitudinal slit extended completely across said body whereby said body may be distended from its original shape, a pair of outwardly extending projections connected to said body remote from said slit for accommodating a force-applying tool, said body being resiliently urged to maintain its origInal tubular shape whereby the original tubular shape of said body may be distended upon application of force to said projections to cause said slit to widen and permit the insertion of a wound flap therein and said body will return toward its original undistended tubular shape upon cessation of the application of force for firmly engaging the wound flap, said slit being defined by a pair of longitudinal edges, and said edges being shaped as sinusoidal teeth having gently merging hills and valleys and wherein said teeth taper outwardly away from said edges, said teeth being defined in cross section by an inner wall disposed toward the interior of said tubular body, said inner walls of said teeth being generally aligned, and each outer wall being inclined from its edge where it merges with its inner wall outwardly away from its inner wall.
Claim 2
Dependent Claim

A hemostatic clip comprising a body in the form of an elongated tubular element, said tubular element having an ellipsoidal cross section, wound-flap-engaging means on said body, said wound-flap-engaging means being an elongated longitudinal slit extended completely across said body whereby said body may be distended from its original shape, a pair of outwardly extending projections connected to said body remote from said slit for accommodating a force-applying tool, said body being resiliently urged to maintain its origInal tubular shape whereby the original tubular shape of said body may be distended upon application of force to said projections to cause said slit to widen and permit the insertion of a wound flap therein and said body will return toward its original undistended tubular shape upon cessation of the application of force for firmly engaging the wound flap, said slit being defined by a pair of longitudinal edges, and said edges being shaped as sinusoidal teeth having gently merging hills and valleys and wherein said teeth taper outwardly away from said edges, said teeth being defined in cross section by an inner wall disposed toward the interior of said tubular body, said inner walls of said teeth being generally aligned, and each outer wall being inclined from its edge where it merges with its inner wall outwardly away from its inner wall.
Claim 3
Dependent Claim
17 words
A clip as set forth in claim 1 wherein said body is made of a polymer material.
Claim 4
Dependent Claim
18 words
A clip as set forth in claim 2 wherein the sinusoidal curvatures of said teeth are generally parallel.
Claim 5
Dependent Claim
107 words
A clip as set forth in claim 3 wherein each of said projections is joined to said body along a longitudinal line disposed about 90* from said longitudinal slit, each of said projections comprising a stem portion connected to said body and a head portion connected to said stem portion, said stem portion and said head portion being of different cross-sectional widths with respect to a section line taken perpendicular to the longitudinal axis of said body to facilitate the reception of a force-applying tool thereon, and said head portion being of generally circular cross section and being solid with a greater width than said stem portion.
Claim 6
Dependent Claim
102 words
A hemostatic clip comprising a body in the form of an elongated tubular element, wound-flap-engaging means on said body, said wound-flap-engaging means being an elongated slit extending completely across said body whereby said body may be distended from its original shape, a plurality of parallel peripheral slots being in said body and terminating adjacent said longitudinal slit with a longitudinal margin on each side of said slit forming a thin backbone to provide stability and to control the flexibility of said body, and said body being at least 10 inches long and being axially bendable for clamping a relatively long wound flap.
Claim 7
Dependent Claim
102 words
A hemostatic clip comprising a body in the form of an elongated tubular element, wound-flap-engaging means on said body, said wound-flap-engaging means being an elongated slit extending completely across said body whereby said body may be distended from its original shape, a plurality of parallel peripheral slots being in said body and terminating adjacent said longitudinal slit with a longitudinal margin on each side of said slit forming a thin backbone to provide stability and to control the flexibility of said body, and said body being at least 10 inches long and being axially bendable for clamping a relatively long wound flap.
Claim 8
Dependent Claim
24 words
A clip as set forth in claim 5 wherein the edges of said slit are serrated to provide positive traction on the wound flap.
