Abstract: A multi-contact wire structure electrode comprises a plurality of parallel strands of rope wire structures wound into a helical structure, two or more proximal stimulating electrodes formed by uncoated regions of the rope wire structures, and one or more distal connectors for electrical interfacing, wherein the distal connectors are configured for connection to an implantable pulse generator. A delivery system for inserting a partially helical wire structure electrode comprises an outer cannula configured to contain a partially helical wire structure electrode having a helical region and a non-helical region, and an inner sleeve positioned within the outer cannula configured to contain the non-helical region and extending to a transition region between the helical region and the non-helical region, wherein the inner sleeve mechanically stabilizes the non-helical region during insertion.

Abstract: Disclosed is a high surface area electrode assembly, for use as an invasive device, which is porous and has significantly more surface area over prior art invasive electrodes. Various embodiments incorporate a high surface area electrode into a nonconductive layer or length or a DBS-like versions suitable for deep brain stimulation and the like.

Abstract: An injectable wire structure electrode can assimilate with surrounding tissues after injection, inducing in-growth of blood vessels, collagen and other tissue. Assimilation secures the electrode to the tissue without sutures and prevents relative motion which can lead to inflammation and scarring. Associated methods of manufacturing and injection are disclosed, as well as systems including a dermal multiplexer for power delivery.

Abstract: A system for stimulating a tissue target in a body with an injectable electrode, either fully or partially implanted, may employ a protection device to prevent over-voltage or over-current from an external pulse generator (EPG) to the injectable electrode. Current is supplied from the EPG transcutaneously to the fully implanted injectable electrode and percutaneously to the partially implanted injectable electrode by various electrical connectors.

Abstract: A system and associated methods for injection of a substantially linear and flexible medical device within a body. The system uses markings on a needle and on a plunger to guide the clinician in withdrawing a needle and advancing a plunger to create 3D anchors out of a substantially linear device.

Abstract: A cured electrode comprising a mixture comprising conductive elements and a carrier which, upon injection into a body, cures from a liquid phase at a first time to a biocompatible solid phase at a second time at or on a target tissue within the body. The cured electrode is capable of being molded around contours of the target tissue so that, after curing, the cured electrode retains the contours of the target tissue. The cured electrode is capable of conducting electricity at a resistance of less than 10 ohm meters in the liquid or the solid phases. Carrier materials include hydgrogel, silicone, bone cement, cyanoacrylate, dental resin and a fibrin mix. The carrier material may also be used to anchor the cured electrode and provide great stability.
