Abstract
Abstract A prosthetic device for repairing or replacing connective tissue such as ligaments and tendons in the human or animal body is described. The device comprises a cord of artificial connective tissue formed from a composite, partly absorbable thread. The thread comprises a combination of permanent material and absorbable material susceptible to being dissolved into surrounding living tissue. The dissolving of the absorbable material leaves space for the living tissue to grow into and adhere to the structure formed by the permanent material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A method for repairing a connective tissue lesion such as a tendon, linear ligament or capsular ligament, and for promoting the regrowth of at least one damaged portion of the tissue toward its point of attachment, which comprises: attaching to said portion one of each end of a plurality of lengths of composite thread comprising a core of filament coated with an absorbable composition; said core filaments being braided together; and said plurality of composite threads being braided together into a length of rope; tauntly securing the other ends of thread to said point of attachment; and allowing growth of the tissue around the lengths of thread.
Claim 2
Independent Claim
107 words
A method for repairing a connective tissue lesion such as a tendon, linear ligament or capsular ligament, and for promoting the regrowth of at least one damaged portion of the tissue toward its point of attachment, which comprises: attaching to said portion one of each end of a plurality of lengths of composite thread comprising a core of filament coated with an absorbable composition; said core filaments being braided together; and said plurality of composite threads being braided together into a length of rope; tauntly securing the other ends of thread to said point of attachment; and allowing growth of the tissue around the lengths of thread.
Claim 3
Dependent Claim
56 words
The method of claim 1, wherein the step of attaching said one of each end to said point of attachment comprises: capping said ends with a mesh made of woven composite suture coated with an absorbable composition; drilling into a bone a bore commensurate with said capped ends; and tieing said capped ends into said bone.
Claim 4
Dependent Claim
29 words
The method of claim 1, wherein the step of attaching comprises braiding each of said composite thread with a plurality of lengths of sutures coated with an absorbable composition.
