Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
An implantable prosthetic device comprising a compressible fluid reservoir, jaw means transportable between an ''''open'''' and a ''''closed'''' condition, the jaw means being biased towards one of these conditions, and a fluid expandable actuating member connected to the reservoir by a fluid duct, the actuating member being adapted to transpose the jaw means to the other of said conditions upon being expanded by the compression of the fluid reservoir, said jaw means comprising three spaced apart parallel arms, the arms being connected together by a bight portion and being so disposed as to be, when viewed in cross-section, at the apices of a notational equilateral triangle.
Claim 2
Dependent Claim
106 words
An implantable prosthetic device comprising a compressible fluid reservoir, jaw means transportable between an ''''open'''' and a ''''closed'''' condition, the jaw means being biased towards one of these conditions, and a fluid expandable actuating member connected to the reservoir by a fluid duct, the actuating member being adapted to transpose the jaw means to the other of said conditions upon being expanded by the compression of the fluid reservoir, said jaw means comprising three spaced apart parallel arms, the arms being connected together by a bight portion and being so disposed as to be, when viewed in cross-section, at the apices of a notational equilateral triangle.
Claim 3
Dependent Claim
39 words
An implantable clamp as claimed in claim 1, in which the actuating member comprises a balloon disposed along one aRm of the jaw means, the jaw means being biased to the open position by the elasticity of the balloon.
Claim 4
Dependent Claim
24 words
An implantable clamp as claimed in claim 1, in which an operable one way valve is provided between the reservoir and the fluid duct.
Claim 5
Dependent Claim
25 words
An implantable clamp as claimed in claim 1 in which the reservoir, the fluid duct and the actuating means are filled with a silicone oil.
