Abstract: A device has been developed to augment the rotator cuff tendon tissue as it proceeds in healing. The device has two purposes: to provide initial stability to the rotator cuff repair site to allow early mobilization of the upper extremity of the patient, and to allow for reinforcement of rotator cuff tendon repairs to increase the likelihood of successful rotator cuff tendon repairs. The device consists of an inter-connected, open pore structure that enables even and random distribution and in-growth of tendon cells. The braided structure allows for distribution of mechanical forces over a larger area of tissue at the fixation point(s).

Abstract: An interwoven sandwich panel structure made for high intensity impulse mitigation comprises a top and bottom face panel integrally interwoven to a core by creating a preform from the interweaving of cross-wise and length-wise threads and then infusing it with a thermoset polymer resin such that it requires no stitching, bonding, or fastening to attach core to the face panels removing the primary weak points of a sandwich panel structure.
