Electrode device for monitoring and/or stimulating activity in a subject

Abstract

An electrode device is disclosed comprising: an elongate, implantable body comprising elastomeric material, a plurality of electrodes positioned along a length of the implantable body; an electrical connection comprising one or more conductive elements extending through the elastomeric material and electrically connecting to the electrodes; and a reinforcement device extending through the elastomeric material. The length of the implantable body is extendible by placing the implantable body under tension. The reinforcement device limits the degree by which the length of the implantable body can extend under tension. At least one of the electrodes can extend circumferentially around a portion of the implantable body. A delivery device and method of delivery for an electrode device is also disclosed.

1 . An electrode device comprising:
 an elongate, implantable body comprising elastomeric material, and   a plurality of electrodes positioned along a length of the implantable body;   an electrical connection comprising one or more conductive wires extending through the elastomeric material and electrically connecting to the electrodes;   wherein at least one of the electrodes extends circumferentially around a portion of the implantable body.
