Sock-like and “button”-type surgical implants, as well as kits containing such devices for use by a surgeon during an operation, are disclosed for surgically reattaching a tendon or ligament to a bone. In sock-like implants, a “toe” portion (or “distal tip”) will receive and hold a bone dowel, which can be pressed into a hole drilled into a bone surface, to anchor and hold the implant in position. “Button” implants can use a “nipple” component to hold a bone dowel anchor. The remainder of either type of implant will contain specialized repair cells, including platelets and “stromal precursor cells”. These implants can be made from placental membranes, treated-collagen membranes or meshes, or other biological materials, to further enhance their ability to stimulate the reattachment of damaged tendons and ligaments to bones.
A surgical implant device designed and sized for attaching a damaged tendon or ligament to a bone surface, comprising a cylindrical membrane made of a biological material which can promote cell growth, having a first end which is open, and a second end which is closed, and which has a diameter at the closed end which is suited for receiving and holding a bone dowel that has been removed from a large bone via a trocar, for anchoring said implant device and said bone dowel in a hole that has been drilled into a bone surface at an attachment location where a tendon or ligament needs to be reattached to a bone surface.
A surgical implant device designed and sized for attaching a damaged tendon or ligament to a bone surface, comprising at least one skirt component made of a processed collagen mesh, and at least one anchoring sleeve which has a diameter at the closed end which is suited for receiving and holding a bone dowel that has been removed from a large bone via a trocar, for anchoring said anchoring sleeve, holding said bone dowel, in a hole that has been drilled into a bone surface at an attachment location where a tendon or ligament needs to be reattached to a bone surface.
