1. A mount for a prosthetic device comprising:
- an endoprosthesis component;
the endoprosthesis component configured to be osseointegratable;
the endoprosthesis component having a borehole therethrough;
a channel in the endoprosthesis component extending at least along a portion of the length of the endoprosthesis component;
a connector mount having a longitudinal borehole therethrough;
the connector mount having a surface and a channel extending longitudinally along the surface of the connector mount alignable with the endoprosthesis component channel;
a cover component complimentary in shape to a portion of the connector mount and connectable thereto, wherein when connected to the connector mount a space between the cover component and the connector mount exists to accommodate one or more wires;
the channel in the surface of the connector mount configured to accommodate a barrier;
a pylon having a longitudinal borehole therethrough;
the pylon having an outer diameter smaller than the boreholes in the connector mount and the endoprosthesis component;
a bolt having threads on at least a portion;
the bolt sized to fit through the boreholes in the pylon and connector mount;
wherein the bolt is threadedly engageable in the borehole of the endoprosthesis component.

Abstract
The invention includes an osseointegrated mount and electrical connector, suitable for providing neural control and sensory feedback for an advanced prosthetic limb. The device provides a channel in which a lead wire from the peripheral nerve interface can travel from the electrical connector down the side of the device or within the device to limit potential sites of infection to a single transcutaneous breach. The channel allows for a silicone barrier to be installed between the internal and external components.

10. A mount for a prosthetic device comprising:
-
an endoprosthesis component having a first conical collar section having a base and a second conical section having a base, the bases of which abut one another, and the longitudinal center lines of the first and second conical sections in line with one another; the endoprosthesis component configured to be osseointegratable; the endoprosthesis component having a borehole therethrough; the first conical section having a surface; a channel in the first conical section surface extending from the base to an apex, the channel having a hook-shaped cross-sectional profile; a first cylindrical connector mount section having an outer diameter substantially the same as the first conical section apex outer diameter and having a longitudinal borehole there through; a channel extending longitudinally along the surface of the first cylindrical connector mount section; a cover component complimentary in shape to a portion of the first cylindrical connection mount section surface and configured to cover the first cylindrical connector mount section channel; the cover having at least one flange complimentary in shape to an indentation in the first cylindrical connector mount section; a second cylindrical connector mount section having an outer diameter substantially the same as the outer diameter of the of the first cylindrical connector mount section; a channel extending longitudinally along the surface of the second cylindrical connector mount section; a barrier disposed in the channel in the surfaces of the first and second connector mounts; a flange extending longitudinally along a channel edge of the second cylindrical connector mount section; a pylon having a shaft and a head and a longitudinal borehole therethrough; the pylon having an outer diameter smaller than the boreholes in the first and second cylindrical connector mount sections and the endoprosthesis component; a bolt having a shaft, the shaft having threads on at least a portion; the bolt sized to fit through the boreholes in the pylon, and first and second cylindrical connector mount sections; and the bolt threadedly engageable in the borehole of the endoprosthesis component.
