IMPLANTS AND TECHNIQUES FOR TISSUE FIXATION AND FUSION
20170296344 · 2017-10-19 ·

A tissue fixation implant that includes leading fixation and trailing fixation members, each fixation member having a proximal head and an elongate shank with a distal tip, and each fixation member adapted to at least partially contact the other fixation member at one or more points along their respective lengths. The tissue fixation implant includes a proximal inter-engagement feature for fixedly engaging each of the two fixation members relative to one another when engaged within tissue, including bone tissue, soft tissue, and combinations of these, and has an interior chamber suitable for receiving osteogenic material to enhance new bone growth and fusion of the fixation implant within bone.

Pressure forming of metal and ceramic powders

A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.

Methods of designing high x-ray lucency lattice structures

The biocompatible lattice structures disclosed herein with an increased or optimized lucency are prepared according to multiple methods of design disclosed herein. The methods allow for the design of a metallic material with sufficient strength for use in an implant and that remains radiolucent for x-ray imaging.

Bone graft delivery devices, systems and kits

A bone graft delivery kit includes a hollow tube having a proximal end and a distal end. The hollow tube is configured to convey graft material to a graft receiving area in a patient. The hollow tube can be connected to an implant. The kit further includes a plunger to facilitate moving the graft material through the hollow tube.

Porous surgical implant and method of making same

A surgical implant and a method for the making the surgical implant is provided. The surgical implant includes various granules incorporated into an upper surface and a lower surface of a body portion thereof. The granules can be pressed into the upper surface and the lower surface via physical force using at least one mold portion. The physical force applied by the at least one mold portion can deform and/or extrude the upper surface and the lower surface to impregnate these surfaces with the granules. The granules can provide the implant with bioresorbable and/or mechanically-reinforced properties.

A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a base plate and a post selectively removable from the base plate. Further, an outer surface of the post includes a layer of the bone ingrowth material along substantially the entire length of the post.

Surface Structuring Method for an Implant, A Counter-Body, and an Implant

A method for structuring a surface of an implant (100) made from a plastic material by means of a counter-body (200) comprises the following steps: providing (S110) of a counter-body (200) including a surface (210); forming (S120) of a first surface structure (212) on the surface (210) of the counter-body, wherein a first surface structure (212) comprises a non-regular, randomly distributed pattern; and forming (S130) of a second surface structure (112) on the implant (100) by using the counter-body (200), wherein the second surface structure and the first surface structure (212) are complementary to each other.
