Claim Text:
1. A tendon repair implant for repair of a partial thickness tear of a tendon, the tendon repair implant comprising: a sheet-like structure formed of reconstituted collagen material, the sheet-like structure defined by a longitudinal dimension aligned with a load bearing direction of the tendon when positioned thereon, a lateral dimension, and a thickness dimension, wherein the longitudinal dimension is greater than the lateral dimension and the thickness dimension, the sheet-like structure having an initial tensile modulus in the longitudinal dimension of 1 MPa to 50 MPa in the range of 1% to 3% strain prior to implantation, where 0% strain is defined with a 1 N preload applied to the sheet-like structure, and a porosity of 30% to 90% for tissue in-growth, wherein the reconstituted collagen material has a longitudinal alignment of collagen fibers forming longitudinal pathways extending along the longitudinal dimension of the sheet-like structure, and wherein the sheet-like structure is adapted to conform to the surface of the tendon and is configured to have an initial load share representing between 1% to 50% of an anatomical load applied to the tendon and sheet-like structure at the time that the sheet-like structure is affixed to the tendon.
