MAGNESIUM SINGLE CRYSTAL FOR BIOMEDICAL APPLICATIONS AND METHODS OF MAKING SAME

A biomedical implant (16, 18) is formed from magnesium (Mg) single crystal (10). The biomedical implant (16, 18) may be biodegradable. The biomedical implant (16, 18) may be post treated to control the mechanical properties and/or corrosion rate thereof said Mg single crystal (10) without changing the chemical composition thereof. A method of making a Mg single crystal (10) for biomedical applications includes filling a single crucible (12) with more than one chamber with polycrystalline Mg, melting at least a portion of said polycrystalline Mg, and forming more than one Mg single crystal (10) using directional solidification.

Bioabsorbable coatings of surgical devices

Methods of reducing device drag on implantable articles are disclosed herein. The methods include coating the contact surfaces of implantable articles with bioabsorbable lubricating coatings.

Surgical screw and method of performing ligament reconstruction using said screw

This invention relates to a system and a method for affixing soft tissue to bones. The system for fixing soft tissue within a bone tunnel comprising a first fixation member having a proximal end and a distal end and a bore extending from said proximal end to said distal end, said first fixation member is adapted for insertion against a first portion of a soft tissue positioned within a bone tunnel, a second portion of said soft tissue emerging from said bone tunnel; a second fixation member adapted to engage said bore of said first fixation member, having means for restraining disengagement therewith and a proximal end; and a third fixation member adapted to engage said second portion of said soft tissue, having means for coupling onto said proximal end of said second fixation member and restraining disengagement therewith.

BONE ANCHOR FOR ATTACHING A SUTURE THREAD OR LIGAMENT

A bone anchor for attaching a suture thread or ligament comprises a main body extending along a longitudinal axis and having a fork-shaped end portion. The end portion is provided with a first and a second fork arm each extending between a constrained end and a free end and spaced apart by an axial slit for receiving a suture thread. Said first and second fork arms have, at their constrained ends, a transverse notch defining two axial retention shoulders for the suture thread.

IMPLANTS WITH GROOVE PATTERNS AND SOFT TISSUE ATTACHMENT FEATURES

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.

Decorticating Screw

The present invention provides decorticating screws and insertion tools for implanting the decorticating screws. The screws anchor into a first and a second bone to fuse the two bones together. The screws include a rotatable bladed section to decorticate a joint space between the first and second bone. The screws also optionally include a cap to secure the screws in the bone and apply compression to the joint to be fused. In some embodiments, the decorticating screws are useful for sacroiliac (SI) joint fusion.

Shape memory polymer

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.

INTERNAL OSSEOINTEGRATED IMPLANT FOR TRANSFEMORAL AMPUTEE
20220031462 · 2022-02-03 ·

The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

Surgical method, kit of parts, and implant

A surgical method is provided, the method including the steps of: providing an artificial or allograft flexible planar structure; providing an implant, the implant including material liquefiable by mechanical oscillation, exposing a surface region of hard tissue or hard tissue substitute material; positioning the implant on an exposed area of the hard tissue or hard tissue substitute material; and fastening the implant to the hard tissue or hard tissue substitute material by impinging the proximal end of the implant with mechanical oscillation and simultaneously pressing the implant against the hard tissue or hard tissue substitute material while the distal end of the implant protrudes into a cavity of the hard tissue or hard tissue substitute material and regions of the liquefiable material are in contact with the hard tissue or hard tissue substitute material, and thereby liquefying at least a portion of the liquefiable material, and letting the liquefiable material resolidify.

COMPOSITE INTERFERENCE SCREWS AND DRIVERS

The present disclosure relates to a delivery device and screw combination. The combination includes a delivery device comprising a handle and a shaft coupled to the handle, the shaft including a proximal end, a distal end, a non-circular cannulation, and markings along a length of the shaft; an interference screw coupled to the delivery device comprising a proximal end and a distal end, the screw including threads extending in an open helical form from the proximal end to the distal end, a suture bridge located at a distal end of the screw and housed within a slot of the delivery device shaft, and a plurality of runners extending longitudinally along an interior of the screw, the runners housed within grooves of the delivery device shaft; and a suture disposed around the suture bridge, ends of the suture extending through the cannulation of the delivery device shaft.
