Patent number: 10864072Abstract: A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.Type: GrantFiled: October 3, 2018Date of Patent: December 15, 2020Assignee: ROTATION MEDICAL, INC.Inventors: Craig Van Kampen, Nathaniel Zenz-Olson, Thomas A.
