This disclosure provides a novel superelastic nickel-titanium (Nitinol or NiTi) splint/orthotic that maximizes the ability to slowly correct toe deformities by utilizing the viscoelastic properties of the bone. The superelastic Nitinol digital deformity orthotic is safe, can gradually correct digit curves, and ultimately results in better toe alignments compared to contemporary static splints or surgery.

A dynamic porous coating for an orthopedic implant, wherein the dynamic porous coating is adapted to apply an expansive force against adjacent bone so as to fill gaps between the dynamic porous coating and adjacent bone and to create an interference fit between the orthopedic implant and the adjacent bone.


A compression screw comprising: a shaft capable of being stretched, the shaft having a proximal end and a distal end, the proximal end of the shaft comprising a bone-engaging feature and the distal end of the shaft comprising a distal screw thread, and the proximal end of the shaft comprising a drive feature for turning the shaft; wherein inserting the compression screw into bone across a fracture line generates a force, and wherein the force generates a stress in the shaft that causes the shaft to stretch to less than its elastic limit; and wherein, after the shaft is inserted into a bone, the shaft attempts to foreshorten to its original un-stretched condition, thereby generating and maintaining compression across the fracture line.


Apparatus for providing compression within a body, the apparatus comprising: a compression plate comprising first and second opposing regions connected together by at least one elastic bridge member, wherein the at least one elastic bridge member has a non-linear configuration when it is in its unbiased condition but is capable of being elastically deformed to a more linear configuration upon the application of force to the at least one elastic bridge member, and at least one opening formed in each of the first and second opposing regions, wherein the at least one opening in each of the first and second opposing regions is configured to receive a fastener; such that the openings in the first and second opposing regions are separated by a first distance when the at least one elastic bridge member is in its non-linear configuration, and openings in the first and second opposing regions are separated by a second distance when the at least one elastic bridge member is in its more linear configuration, and further wherein the second distance is greater than the first distance.


A method for applying compression to bone, the method comprising: providing a shape memory material device; deforming the shape memory material device using the superelastic properties of the shape memory material device so that the shape memory material device generates a stress level which is at or above the upper plateau of the mechanical hysteresis curve of the shape memory material device; allowing the shape memory material device to recover a portion of its deformation so that the shape memory material device generates a stress level which is substantially at the lower plateau of the mechanical hysteresis curve of the shape memory material device; mechanically constraining the shape memory material device; deploying the shape memory material device so that the shape memory material device is in association with bone; and releasing the mechanical constraint so that the shape memory material device applies compression to bone.

A spinal implant includes a coiled wave spring configured to surround a nucleus. The wave spring is formed with at least one wire having a sinusoidal shape and made of a shape memory material. The shape memory material is tailored to achieve a stress-induced martensitic transformation when a critical stress is exceeded. The implant may further include an artificial nucleus configured to simulate a disc nucleus. Methods of forming and implanting the spinal implant are also disclosed.


A method for providing stabilization and compression of a bone fracture, the method comprising:


A porous coating for a medical implant, wherein the porous coating comprises a porous, shape memory material.

Apparatus for generating, applying and maintaining compression to a site in a human or animal body, the apparatus comprising: a staple comprising: a bridge configured to be elastically bendable; a first leg connected to the bridge by a first hinge region configured to be elastically bendable; and a second leg connected to the bridge by a second hinge region configured to be elastically bendable; wherein the first hinge region comprises a first hole configured to mate with a first element of a delivery device and the second hinge region comprises a second hole configured to mate with a second element of a delivery device; and wherein the first and second legs are angled toward one another when they are in an unstrained state; whereby, when the staple is mounted to a delivery device so that the first hole of the first hinge region mates with a first element of a delivery device and the second hole of the second hinge region mates with a second element of a delivery device, and when the delivery device applies a force to the bridge of the staple so as to reconfigure the bridge of the staple, the first and second legs are pivoted away from one another toward a parallel disposition.
