Devices for neural signal transmission
First Claim
1. A device for transmitting neural signals from a proximal stump of a transected nerve to a prosthetic apparatus, said transmission device comprising:
- a microelectrode capable of sensing electrical signals from a nerve and transmitting said signals to said prosthetic apparatus; and
a guidance channel disposed about said microelectrode, comprising a tubular, semipermeable membrane and having a capped distal end and a proximal end which defines an opening adapted to receive a proximal stump of a transected nerve, whereby said channel promotes the growth of said stump, such that an electrical connection between said transected nerve and said microelectrode can be obtained.

Abstract
Devices and methods for transmitting neural signals from a proximal stump of a transected nerve to a prosthetic apparatus are disclosed employing microelectrodes, preferably conductive fiber networks, capable of sensing electrical signals from a nerve and transmitting such signals to a prosthetic apparatus; and a semipermeable guidance channel disposed about the microelectrodes. The channels include an opening adapted to receive the proximal stump of a transected nerve, such that the channel promotes the growth of the stump and the formation of an electrical connection between the transected nerve and the microelectrode.
