Abstract: The present invention incorporates a neural interface with a skin and bone integrated device with hermetic seal to prevent infection migration through the interface. The neural interface consists of plurality of wires that conduct the signals between the inside body nerve system and the outside robotic/prosthetic mechanisms and controls. Each wire is electrically insulated through the channel of a single, double or multi bore insulator rod. The wires are extended outside on both ends of the rod forming leads for further connection with corresponding wires conducting signals to and from outside and inside body. The rod assembly is inserted inside a channel of a solid tubular load bearing titanium frame. The outside of the ceramic rod is hermetically brazed to the inside of the frame at both ends. The solid tubular frame is surrounded by a porous titanium portion of the pylon ensuring the integration with the skin.

Abstract: A powered ankle/foot prosthetic with a closed-loop, neural, bi-directional intuitive control system can be utilized for transtibial amputees with traditional socket prosthetics or for those with osseintegrated prosthetics. Control (efferent) signals from the user to the prosthesis actuator are captured from EMG of residual gastrocnemius and tibialis anterior muscles. Sensory feedback (afferent) information about contact of the prosthetic foot with the ground obtained from a pressure sensor located on the foot bottom is reported to the user's nervous system by electrical stimulation of the residual trans-tibial and sural nerves. Surgically implanted or skin surface electrodes placed on/within the residual ankle flexor and extensor muscles relay recorded EMG to the control electronics mounted on the linear actuator. The control electronics are designed to generate a more natural powered plantarflexion of the ankle joint based on the EMG data, pressure sensor, and other inertial sensors.

Abstract: An in-bone implantable shaft for prosthetic joints or for direct skeletal attachment of external limb prostheses, comprised of a central body fitted in the zone of the bone's medullary cavity conventionally prepared for implantation, and of side elements attached to the central body and fitted in the slots specially made in the bone's walls surrounding said medullary canal; said side elements have spaces between them, arranged to be filled by bone cells to provide a natural and safe osseolocking of the shaft. A method of preparing the bone for implantation of a prosthetic shaft, comprising the steps of: placing a cylindrical guide with slots made in the longitudinal direction of said guide inside said bone's canal which is conventionally prepared for implantation; cutting said bone's walls by progressing a saw along the edges of the slots of said guide; removing the guide; fitting the shaft in the bone's canal, provided that the side elements are fitted to the slots in the bone's walls.

Abstract: A skin integrated device for implantation with an improved device-skin interface for the ingrowths of skin cells and tissues throughout the pores, having a solid frame, which may also be permeable. The characteristics of pore size, porosity and size of the compressed and sintered particles constitute a long-term skin integrated device for transfer of vital and therapeutic substances, and necessary forces and moments from the outer delivery and prosthetics devices to the human body. The ingrowth of the skin along with the intermittent layer of fine silver provides a barrier for infection.
