Abstract: A device and method of correcting a spinal defect in a patient employs the use of shape memory material in a spinal correction device. The shape memory material may be transitioned between a flexible martensitic state to allow shaping of the spinal correction device and a rigid austenitic state to apply corrective forces to the spine. The shape memory material may be transitioned to the flexible martensitic by applying a coolant, such as cold gas, directly or indirectly to the shape memory material to transfer heat away from the material. The cooling device and method may allow for in-vivo shaping of the spinal correction device while inserted in the body and attached to bone anchors by cooling the spinal correction device after insertion.

Abstract: Disclosed is a polymeric orthopaedic bearing material for use as an implant material or part thereof comprising one or more crosslinked regions and one or more non-crosslinked or substantially non-crosslinked regions at the surface. The bearing material can be prepared from a crosslinkable polymer, e.g., ultrahigh molecular weight polyethylene. The orthopaedic bearing material has an advantageous combination of at least one wear property and at least one mechanical property. Also disclosed are processes for producing orthopaedic bearing materials, for example, by irradiating a raw material in consolidated form through a radiation mask having a perforated pattern for crosslinking selected regions of the raw material, and optionally shaping the raw material into a bearing material. Alternatively, a pulsed radiation beam can be used for crosslinking.
Abstract: A medical inserter tool is provided for introducing medical implants into a surgical site, preferably using minimally invasive techniques. The inserter tool can have a variety of configurations, but in general, the inserter tool should be effective to engage and manipulate the implant into two or more positions. In an exemplary embodiment, the tool includes an elongate shaft having proximal and distal ends and defining a longitudinal axis extending therebetween, and a pivoting element that is coupled to the distal end of the shaft and that is adapted to engage a spinal implant. In use, the pivoting element is movable between first and second positions to allow an implant to be introduced through a percutaneous access device in a lengthwise orientation, and to be manipulated subcutaneously to be positioned in a desired orientation.
