TETROUS, INC. ANNOUNCES ISSUE OF AN ADDITIONAL U.S. PATENT RELATED TO ENFIXtm DEMINERALIZED BONE FIBER IMPLANTS FOR SPORTS MEDICINE SURGICAL PROCEDURES

LOS ANGELES, Oct. 5, 2023 /PRNewswire/ -- Tetrous, Inc., a regenerative medicine company, today announced that another patent (U.S. Patent Number 11,759,548) specifically related to the EnFix family of demineralized cortical bone fiber implants and their method of manufacture has been issued by the United States Patent and Trademark Office.

EnFix RCtm, the first product in the EnFix family, is a procedure-specific implant for rotator cuff repair. It is currently available in the United States and Australia. EnFix RC changes the paradigm in rotator cuff surgery by enhancing healing at the tendon to bone interface, i.e., at the enthesis, where failure often occurs. The 100% demineralized bone fiber (DBF) implants provide osteoinductivity and osteoconductivity in a unique graft, while FormLoktm technology imparts shape retention to the device, even when immersed in liquid, as is typical in arthroscopic surgery. The enhanced biologic repair at the interface between tendon and bone is a significant advancement. Optimal biologic performance is provided in an implant that has minimal disruption to the current surgical technique.

The newly issued patent, titled "Demineralized Bone Fiber Implant Compositions and Methods for Rotator Cuff and ACL Repair", further augments Tetrous' strong portfolio of intellectual property covering demineralized cortical bone fiber implants, bone healing, and enhancement of tendon to bone repair. "We are pleased that the U.S. Patent Office has yet again recognized the uniqueness of our technology and has granted this additional patent.", said Andy Carter, PhD, Tetrous' Co-Founder, Director and co-inventor on the issued patent. "Our growing intellectual property portfolio provides Tetrous a sustainable competitive advantage in the next-generation enthesis repair market".
