Abstract
Abstract A surgical clamp for application to the neck of an aneurism to clamp the walls thereof to shut off blood flow or seepage from an artery on which such aneurism has formed, the clamp having oppositely, longitudinally concavely bowed, and resiliently biased clamping arms that are also transversely, oppositely convexly bowed, and the opposed faces of said arms being provided with a multiplicity of depressions that are defined by intersecting portions of said opposed faces.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
An aneurism clamp comprising: a. a pair of clamping arms having proximal and distal ends and having opposed clamping faces, said arms being pivoted intermediate said ends and adapted for clamping engagement with the outer surfaces of the walls of an arterial vessel; b. spring means resiliently biasing said arms into clamping position; c. the distal ends and intermediate portions of said arms being curved transversely to provide a convex inner surface throughout the length thereof and said arms being bowed outwardly and oppositely intermediate their ends providing a space therebetween, the distal ends of each of the arms being in contact when the clamp is closed, the intermediate spaced portions providing aneurism-engaging portions; d. an operating arm on the proximal end of each clamping member, a portion of the spring means engaging each operating arm; and e. a hook on the end of each operating member, said hooks being oppositely formed to provide means for reception of an applier instrument to spread the clamping arms to receive the neck of an aneurism.
Claim 2
Dependent Claim
173 words
An aneurism clamp comprising: a. a pair of clamping arms having proximal and distal ends and having opposed clamping faces, said arms being pivoted intermediate said ends and adapted for clamping engagement with the outer surfaces of the walls of an arterial vessel; b. spring means resiliently biasing said arms into clamping position; c. the distal ends and intermediate portions of said arms being curved transversely to provide a convex inner surface throughout the length thereof and said arms being bowed outwardly and oppositely intermediate their ends providing a space therebetween, the distal ends of each of the arms being in contact when the clamp is closed, the intermediate spaced portions providing aneurism-engaging portions; d. an operating arm on the proximal end of each clamping member, a portion of the spring means engaging each operating arm; and e. a hook on the end of each operating member, said hooks being oppositely formed to provide means for reception of an applier instrument to spread the clamping arms to receive the neck of an aneurism.
Claim 3
Dependent Claim
28 words
A surgical clamp as defined in claim 1, wherein each clamping face is provided with a plurality of cavities into which portions of the vessel wall are forced.
Claim 4
Dependent Claim
33 words
A surgical clamp as defined in claim 1, wherein the spring means is a coil spring coaxial with the pivot axis of said arms and having opposite ends bearing against said operating members.
