Abstract
Abstract This is a hemostatic clip for clasping the flaps of a wound together and holding them together to prevent bleeding and to promote healing until the wound is healed and in closed position, whereupon it is released. It is made in a generally tubular body form with a longitudinal slit having cooperating teeth on the slit edges. It is made of a suitable resilient metal or plastic material. Opposite the elongate slit, the tubular body is provided with an inwardly extending longitudinal U-shape depression which, when pressure is applied to the sides of the U, will cause the slit and teeth to separate, whereby it can be applied to the wound flaps. When the pressure is released, the teeth will grasp and hold the wound flaps in contact. When the wound has healed sufficiently, the pressure is again applied to release the teeth from engagement with the flaps. Ridges, eyelets or apertures are provided in the tubular body to cooperate with a pair of plyers for applying suitable pressure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
252 words
A hemostatic clip for applying a predetermined pressure to opposite wound flaps comprising a sheet of resilient material in the form of an elongated tubular body (10, 30, 31), wound flap engaging means (12, 14) on said tubular body, said wound flap engaging means being the edges (12) of an elongated slit extending longitudinally of said tubular body and longitudinally spaced apart teeth (14) on both slit edges extending toward each other in normal contacting relation, a portion of the periphery of said tubular body being bent radially inwardly, at a location diametrically opposite said slit, to form an upwardly open channel substantially U-shaped in cross-section and extending the entire length of the tubular body and providing an integrally formed resilient hinge section, the portions of the periphery of said tubular body on opposite sides of said channel being provided with means for receiving the jaws of a plier, whereby force may be applied to said body on opposite sides of said resilient hinge section and against the bias thereof to separate said teeth and hold them separated while applying said teeth to opposite wound flaps, and when the pressure is released, said teeth and slit edges will be resiliently biased to move the wound flaps toward contact with each other and then hold the wound flaps in predetermined pressure contact until such time as pressure is again applied to said tubular body to separate said slit edges and teeth from contact with the wound flaps to thus release the wound flaps.
Claim 2
Dependent Claim
252 words
A hemostatic clip for applying a predetermined pressure to opposite wound flaps comprising a sheet of resilient material in the form of an elongated tubular body (10, 30, 31), wound flap engaging means (12, 14) on said tubular body, said wound flap engaging means being the edges (12) of an elongated slit extending longitudinally of said tubular body and longitudinally spaced apart teeth (14) on both slit edges extending toward each other in normal contacting relation, a portion of the periphery of said tubular body being bent radially inwardly, at a location diametrically opposite said slit, to form an upwardly open channel substantially U-shaped in cross-section and extending the entire length of the tubular body and providing an integrally formed resilient hinge section, the portions of the periphery of said tubular body on opposite sides of said channel being provided with means for receiving the jaws of a plier, whereby force may be applied to said body on opposite sides of said resilient hinge section and against the bias thereof to separate said teeth and hold them separated while applying said teeth to opposite wound flaps, and when the pressure is released, said teeth and slit edges will be resiliently biased to move the wound flaps toward contact with each other and then hold the wound flaps in predetermined pressure contact until such time as pressure is again applied to said tubular body to separate said slit edges and teeth from contact with the wound flaps to thus release the wound flaps.
Claim 3
Dependent Claim
25 words
The hemostatic clip of claim 1, wherein said means for receiving comprises an aperture in each of the portions on opposite sides of the channel.
Claim 4
Dependent Claim
32 words
The hemostatic clip of claim 1, wherein said means for receiving comprises an outwardly extending ridge formed on each said portion of the periphery which is on opposite sides of the channel.
Claim 5
Dependent Claim
30 words
The hemostatic clip of claim 1, wherein said means for receiving comprises an eyelet secured to each said portion of the periphery which is on opposite sides of the channel.
Claim 6
Dependent Claim
31 words
The hemostatic clip of claim 1 wherein said means for receiving comprises a pocket member secured to each said portion of the periphery which is on opposite sides of the channel.
