Abstract
A medical electrode device, implantable in a subject for electrically stimulating tissue, includes an electrode cable containing an elongated, flexible conductor having an interior channel and covered with electrical insulation, and terminating in an electrode head for engaging tissue of the subject. A stylet is insertable in the channel. The electrode device incorporates structure for assisting in explanting the device formed by an adhesive substance releasably storable within the cable and releasable by manipulation of the stylet or a stylet-like element. When the adhesive is released, the stylet is adhered to the electrode head and can be manipulated from the proximal end of the electrode device to twist the distal end of the electrode device away from ingrown tissue upon explantation.
