Abstract: A transcutaneous port includes a subcutaneous port section and a bone fixation section. The subcutaneous port section has upper portion which has an axial channel and a first micro-textured external surface, and a lower portion which has therein a transverse channel connecting to the axial channel. The bone fixation section has a transosseous collar portion which has a second micro-textured external surface, and a threaded shaft portion. The first and second micro-textured external surfaces include a multiplicity of alternating microgrooves and ridges for tissue and bone integration. The transcutaneous port is surgically implanted into a site of a patient and a conductive wire is introduced from the axial channel to the transverse channel, and placed in the subcutaneous soft tissue and in contact with a neural signal source for transmitting neural signals to a prosthetic motor device.

Abstract: Protection has been critical to residential and commercial owners for thousands of years. This is still so, though possibly more so, in today world. Stationary Burglar bars placed over residential and commercial property windows provide a readily visible sign of security. This sign serves both as a deterrent to would-be thieves and an assurance of safety to property owners. As criminal activity has increased, utilization of burglar bars has expanded in cities and towns across the entire United States in response to the ever-increasing threat. Unfortunately, however successful as a security measure, Burglar bars have also proved to be dangerous. First, stationary burglar bars can create death traps or lead to severe injuries for property occupants by blocking escape in the event of a fire. Second, Fire rescue and EMS personnel often encounter obstacles specific to stationary burglar bars that impede their rescue and/or firefighting efforts, as well as threatening their personal safety.

Abstract: Polymer containing calcium sulfate particles as an implant material are provided. The polymer containing calcium sulfate particles include a calcium sulfate compound coated with a therapeutic polymer containing salicylate, with a coating thickness from about 2 ?m to about 50 ?m.

The polymer containing calcium sulfate particles can be used as an implant material for bone repairing and bone augmentation.

In some embodiments of the invention, such a material includes a plurality of particles having a predetermined size and comprising a first calcium sulfate compound and a resorbable polymer in a predetermined weight ratio. Methods for making such a material include rotating calcium sulfate powder in a drum at a first predetermined drum speed, spraying of a resorbable polymer solution at a predetermined rate on the calcium sulfate powder over a predetermined period of time and drying the resulting particles. Such compositions allow resorption rates of the implant composition in vivo to be controlled, and my vary between eight and twenty-four weeks (for example), which can be matched to substantially correspond to a rate of bone growth in a particular application.
