A device includes a bone cement or a biomaterial and a mesh structure impregnated with the bone cement or the biomaterial. The mesh structure reinforces the bone cement or the biomaterial and reinforces the materials fatigue properties. The mesh structure may be made of a shape memory alloy.


Patent
Mx Orthopedics | Date: 2016-09-02

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.


Apparatus for compression, comprising: a compression plate comprising first and second opposing regions connected together by an elastic bridge member, wherein the elastic bridge member has a non-linear configuration in its unbiased condition but is capable of being elastically deformed to a more linear configuration upon application of force to the elastic bridge member, and an opening formed in each of the first and second opposing regions, wherein the 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 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 elastic bridge member is in its more linear configuration, and 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.


This disclosure provides novel devices for controlling the unloading stress and recoverable strain of Nitinol devices and/or other shape memory material devices. The devices may be used to bring bone fragments into close proximity with each other, generate a compressive load between the bone fragments, and maintain that compressive load between the bone fragments while healing occurs.


Patent
Mx Orthopedics | Date: 2016-10-07

This disclosure describes exemplary screw and intramedullary devices that are better able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The devices are made of a shape memory material.


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.


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.
