Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
An orthopaedic staple comprising an elongate member of biocompatible metal formed to a generally U-shape with parallel arms, the free end portions of said arms being tapered predominantly on their mutually facing surfaces, said arms being formed with retraction-resisting barbs by notches in said facing surfaces. and the staple being of sufficiently greater rigidity relative to bone to be substantially unyielding in shape when penetrated into bone to bridge a fracture, whereby such penetration exerts compressive force across said fracture to reduce the same by the action of said tapering, and bone material is urged into said notches by said force.
Claim 2
Dependent Claim
101 words

Claim 3
Dependent Claim
17 words
A staple according to Claim 1 wherein said arms are tapered only on their mutually facing surfaces.
Claim 4
Dependent Claim
25 words
A staple according to Claim 2 wherein said tapers extend wholly across each of said arms to provide cutting edges at the free end thereof.
Claim 5
Dependent Claim
27 words
A staple according to any preceding claim wherein the base of said U-shape is of non-symmetrical inclined disposition relative to said arms, or is of stepped configuration.
Claim 6
Dependent Claim
12 words
A staple substantially as herein described with reference to the accompanying drawing.
Claim 7
Dependent Claim
12 words
A staple substantially as herein described with reference to the accompanying drawing.
