Claim Text:
1. A tendon repair implant for repair of a partial thickness tear of a supraspinatus tendon, the tendon repair implant comprising: a sheet-like structure comprising a reconstituted collagen material, the sheet-like structure having a first compact configuration for delivery from an arthroscopic instrument and a second planar configuration having a longitudinal dimension, a lateral dimension, a thickness dimension, and a longitudinal surface, wherein the longitudinal surface is conformable to a bursal side surface of the supraspinatus tendon and the longitudinal dimension is aligned with a load bearing direction of the supraspinatus tendon when positioned thereon, wherein the sheet-like structure has an initial tensile modulus of 1 MPa to 100 MPa in the range of 1% to 3% strain in the longitudinal dimension 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%, and wherein the sheet-like structure includes longitudinal pathways defined in the thickness dimension for at least some tissue in-growth oriented in the longitudinal dimension, wherein the reconstituted collagen material has a longitudinal alignment of collagen fibers in the longitudinal dimension to form the longitudinal pathways.
