Abstract
Abstract A vascular clamp includes a plurality of elongated jaws operatively connected together for movement from an open position to a clamping position. At least one of the jaws is provided with a resilient gripping member. A plurality of pin members are imbedded into the resilient gripping member and extend generally in the direction of the clamping motion of the jaw on which the resilient gripping member is provided. The inner end of the pin members is fixedly positioned with respect to the jaw on which the resilient member is provided. The length of the pin members is such that their outer ends lie beneath the outer surface of the resilient clamping member when the jaws are in their open position and extend beyond the outer surface of the resilient member when the jaws are in their clamping position. When the jaws are in their clamping position, the object being clamped compresses the resilient member and the pins extend beyond the outer surface of the compressed resilient member and thus grippingly engage the object clamped between the jaws.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
A vascular clamp comprising a pair of elongated jaws operatively connected together for clamping movement from an open position in which the jaws are separated from one another to a clamping position in which the jaws are in adjacency, at least one of said jaws comprising a resilient gripping member positioned on said jaw at a surface thereof facing the other jaw, said resilient gripping member having imbedded therein a plurality of elongate pin members extending generally in the direction of the clamping motion of the jaw on which the resilient member is provided, one end of said pin members being fixedly connected to said jaw, said pin members having a length such that their other ends lie under the outer surface of said resilient gripping member facing the other jaw when the jaws are in their open position and extend beyond the said outer surface of said resilient gripping member when the jaws are in their clamping position with said resilient member being compressed by an object being clamped between said jaws, whereby the outer ends of said pin members grippingly engage an object clamped between said jaws.
Claim 2
Dependent Claim
189 words
A vascular clamp comprising a pair of elongated jaws operatively connected together for clamping movement from an open position in which the jaws are separated from one another to a clamping position in which the jaws are in adjacency, at least one of said jaws comprising a resilient gripping member positioned on said jaw at a surface thereof facing the other jaw, said resilient gripping member having imbedded therein a plurality of elongate pin members extending generally in the direction of the clamping motion of the jaw on which the resilient member is provided, one end of said pin members being fixedly connected to said jaw, said pin members having a length such that their other ends lie under the outer surface of said resilient gripping member facing the other jaw when the jaws are in their open position and extend beyond the said outer surface of said resilient gripping member when the jaws are in their clamping position with said resilient member being compressed by an object being clamped between said jaws, whereby the outer ends of said pin members grippingly engage an object clamped between said jaws.
Claim 3
Dependent Claim
34 words
A vascular clamp according to claim 1 wherein said pin members comprise pointed needles having a diameter of not more than 10 mils, the points being provided at the outer ends of said needles.
Claim 4
Dependent Claim
20 words
A vascular clamp according to claim 2 wherein the spacing between adjacent pin members is from 0.03 to 0.25 inches.
Claim 5
Dependent Claim
55 words
A vascular clamp according to claim 1 wherein the length of said pin members is such that they extend a distance of not more than 3 mm beyond the outer surface of said resilient gripping member when the jaws are in their clamping position with said resilient gripping member compressed by the object being clamped.
Claim 6
Dependent Claim
20 words
A vascular clamp according to claim 1 wherein each of said jaw members is provided with a resilient gripping member.
Claim 7
Dependent Claim
21 words
A vascular clamp according to claim 5 wherein each of said resilient gripping members includes a plurality of said pin members.
