Abstract
Abstract A prosthetic ligament is constructed from a three-dimensional braider. The prosthetic ligament includes an eyelet at a first end and a pigtail at a second end. The pigtail is removed during surgery so that the remaining implantable prosthetic ligament is defined by a continuous three-dimensional braided structure from the eyelet at the femur to the other end at the tibia.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
207 words
A prosthetic device for repair or replacement of tissue connected to a bone, the prosthetic device including a first end with an eyelet to receive fixation means for securing the first end to the bone, a second end of reduced outer diameter for insertion into a tunnel formed in the bone, and an intermediate section connecting the first end and the second end, the second end and intermediate section defines a canal extending from an opening at the second end to an opening at the eyelet at the first end, the first end and the intermediate section being formed with a first uniform braid of a plurality of fibers and the second end being formed with a second uniform braid from a portion of the plurality of fibers, the second uniform braid being different from the first uniform braid wherein said first uniform braid is defined by a three dimensional braid for the plurality of fibers, the second end serving as a guide for insertion of the second end through the bone channel so that the intermediate section adjacent the second end is adapted for fixation to another bone and the second end is cut off after the first end and intermediate section are secured to bone.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The prosthetic device of the claim 1 in which the second uniform braid is defined by a two-dimensional braid for the portion of the plurality of fibers.
