  • Patent number: 9498335
    Abstract: This application describes an implantable device for tissue repair comprising at least two fabrics with interconnecting spacer elements transversing, connecting, and separating the fabrics, forming the device. Some embodiments have fixation points which can be an extension of at least one of the fabrics. The implantable device allows modification of the two fabrics having varying constructions, chemistries, and physical properties. The spacer elements create a space between the two fabrics, which can be used for the loading of biological materials (peptides, proteins, cells, tissues), offer compression resistance (i.e. stiffness), and compression recovery (i.e., return to original dimensions) following deformation and removal of deforming load. The inclusive fixation points of the fabrics are designed to allow for fine adjustment of the sizing and tension of the device to promote integration with the surrounding tissues as well as maximize the compressive resistance.

  • Patent number: 9468518
    Abstract: A tendon anchoring device may include an implant having a pair of spaced apart legs for straddling a tendon. A push rod removably attached to the implant may be utilized to guide and push a portion of the tendon into a pre-drilled bore in a bone. A fixation member may be slid along the push rod and threadably engage an inner surface of the pre-drilled bore to thereby anchor the tendon to the bone while a force is applied to the push rod. Once the fixation member has been installed, the push rod may be disengaged from the implant and removed from the bore. The implant may remain permanently straddled over the tendon inside of the bore.
