An orthopaedic implant includes an implant body comprising a biocompatible material and configured to be implanted at an anatomical location, the implant body defining a surface; and a porous material at least one of attached to and integral with the surface of the implant body, the porous material having a plurality of grooves formed therein.

A polymer is composed of a linear chain acrylate and a multi-functional acrylate cross-linker. The polymerized composition exhibits a transition at a temperature between about 34° C. and about 50° C. The polymerized composition exhibits shape memory effects. In one embodiment, the linear chain is tert-butyl acrylate and the crosslinker is polyethylene glycol dimethacrylate. The resultant shape memory polymers may be used in medical devices to provide devices with different shapes for pre and post implantation.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.

The present disclosure relates to an anchor for fixating a tissue graft to bone. The anchor includes a through hole extending an entire length of the anchor and a polymer composition having shape memory qualities. Other anchors and methods for fixating a tissue graft to bone are also disclosed.

A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. The suture locking wedge includes lateral portions which engage slots or windows in the anchor body. Tension applied to one limb of a suture causes the suture locking wedge to translate and rotate to a position which compresses the suture, thereby locking the suture in the anchor.

An apparatus and method for the repair of disruptions between bones. The apparatus defines a combination of sleeves, strands and crimps are provided to secure the bones, using a dual sided drill guide to prepare the bones for installation of the apparatus, which is adjusted upon installation to suit the appropriate alignment and tension of the apparatus. The method includes the preparation of the bones, the installation of the apparatus and the adjustment of the apparatus to properly align and tension the apparatus for repair of the bone.

In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.

A surgical bone sheath staple device, anchor, and/or scaffold enables low impact installation of distal end members in bones to secure soft tissue and the like via a deployment system. The bone sheath staples, anchors, and scaffolds secure soft tissue to bone to ensure tailored fixation of soft tissue to bone. The bone staples, anchors, and scaffolds integrate sheath and suture tightening members to secure soft tissue to bone and tailor compression of soft tissue to bone to encourage healing. The bone staples, anchors, and scaffolds integrate sheaths and suture to define attachment mechanisms and other features that secure the staples, anchors, and/or scaffolds to bone.

A ligament assembly comprising a first ligament anchor (9) connected to a second ligament anchor (14) by a ligament (18) a resilient element (40) being associated with the first ligament anchor (9) and a ligament tension adjuster (44, 50) being associated with the second ligament anchor (14). The resilient element (40) may be disposed within the first ligament anchor (9) and the ligament tension adjuster (44, 50) may be disposed within the second ligament anchor (14).
