A cautery safety controller can include a first input to receive a cautery power signal; a first output coupled to a nerve stimulator system; a second input coupled to receive a nerve detected signal; a zero-crossing detector coupled to receive the cautery power signal via the first input and output a nerve sense enable signal via the first output to the nerve stimulator system in response to detecting a zero crossing of the cautery power signal; and a nerve detection decision unit coupled to receive the nerve detected signal via the second input, generate a stop operation signal, and output the stop operation signal via a second output. A cauterizing pencil can be provided with a tap line for providing the cautery power signal. Alternatively, a cautery pad can be provided with a sense electrode for providing the cautery power signal.

The present invention relates to an implant adapted to be implanted at least partially in a biological tissue (20). Today's implants remain very susceptible to mechanical damage. The inventors have thus developed an implant having a greater reliability in terms of resistance to mechanical stress than existing implants, while allowing for easy connection with different parts of a biological tissue. This implant comprises an implant body (30) and a set of electrically conductive wires (55), each wire (55) comprising a first portion (65) electrically connected to the body (30), a second portion (70) and a third portion (75) intended to be electrically connected to the tissue (20), The implant (10) comprises a set of arms (25) comprising each an insulating sheath (60) and a bundle (52) of wires (55), each bundle (52) comprising at least two subsets (62) of wires (55).

An electrode carrier system includes one or more electrode assemblies having an electrode body. One or more tubular members extend from the electrode body and define a lumen terminating in a distal opening. The electrode assemblies carry a reservoir containing a conductive fluid or gel. The reservoir is in fluid communication with the lumens in the tubular members, and the electrode assemblies are typically supported on a backing which may optionally be configured as a headband. Systems are for tracking patient movement may be used in combination with the electrode carrier system.
