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.
