Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A one piece endoprosthetic bone clip for joining bones in vivo under a selected compressive force, comprising: an elongated metallic body member having an elongated slot means in a central portion thereof and having coplanar, unilaterally extending single legs at each longitudinal end thereof; said legs being formed unitarily with and extending substantially perpendicular to said body member; said legs being adapted for insertion into respective predrilled holes in said bones being joined; said body member including arm means, contiguous said slot means, for being plastically deformed in a plane perpendicular to the plane of said legs, so as to draw said legs towards each other in parallel relation, imparting said selected force, and thereby joining said bones.
Claim 2
Dependent Claim
118 words
A one piece endoprosthetic bone clip for joining bones in vivo under a selected compressive force, comprising: an elongated metallic body member having an elongated slot means in a central portion thereof and having coplanar, unilaterally extending single legs at each longitudinal end thereof; said legs being formed unitarily with and extending substantially perpendicular to said body member; said legs being adapted for insertion into respective predrilled holes in said bones being joined; said body member including arm means, contiguous said slot means, for being plastically deformed in a plane perpendicular to the plane of said legs, so as to draw said legs towards each other in parallel relation, imparting said selected force, and thereby joining said bones.
Claim 3
Dependent Claim
22 words
A bone clip as claimed in claim 1 wherein said arm means include notch means intermediate the ends to facilitate deformation thereof.
Claim 4
Dependent Claim
21 words
An endoprosthetic bone clip as claimed in claim 1 wherein said legs include notch means to facilitate gripping in said bones.
