Expandable synthetic sleeve to affix tissue
View Patent ↗Implants and instrumentations for fixation of tissue to bone may be provided. An expandable locking suture sleeve may provide knotless fixation of sutures and soft tissue. The locking suture sleeve may have an internal mechanism to lock extra-sleeve or tissue repair sutures through a locking loop. An insertion device may further be provided. The insertion device may have a cannulated inner wire to hold the locking sleeve sutures. The insertion device may have a driver with a receptable screw that can be advanced down the inner wire. The receptacle screw may be buried into the patient's bone to compress the suture sleeve and further lock the sutures in place. A back handle may be threaded into the screw driver in order to control the advancement of the screw.
