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.

Ex vivo method of manufacturing a wire structure electrode

One aspect of the present disclosure relates to a system that can prevent unintended signal components (noise) in an electric waveform that can be used for at least one of neural stimulation, block, and/or sensing. The system can include a signal generator to generate a waveform that includes an intended electric waveform and unintended noise. The system can also include a signal transformer device (e.g., a very long wire) comprising a first coil and a second coil. The first coil can be coupled to the signal generator to receive the waveform and remove the unintended noise from the electric waveform. The second coil can pass the electric waveform to an electrode. The second coil can be coupled to a capacitor that can prevent the waveform from developing noise at an electrode/electrolyte interface between an electrode and a nerve.

Systems and methods for preventing noise in an electric waveform for neural stimulation, block, or sensing

Devices and methods for blocking signal transmission through neural tissue. One step of a method includes placing a therapy delivery device into electrical communication with the neural tissue. The therapy delivery device includes an electrode contact having a high charge capacity material. A multi-phase direct current (DC) can be applied to the neural tissue without damaging the neural tissue. The multi-phase DC includes a cathodic DC phase and anodic DC phase that collectively produce a neural block and reduce the charge delivered by the therapy delivery device. The DC delivery can be combined with high frequency alternating current (HFAC) block to produce a system that provides effective, safe, long term block without inducing an onset response.

Therapy delivery devices and methods for non-damaging neural tissue conduction block

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.

Described herein are systems and methods for the treatment of pain using electrical nerve conduction block (ENCB). Contrary to other methods of pain treatment, the ENCB can establish a direct block of neural activity, thereby eliminating the pain. Additionally, the ENCB can be administered without causing electrochemical damage. An example method can include: placing at least one electrode contact in electrical communication with a region of a subject's spinal cord; applying an electrical nerve conduction block (ENCB) to a nerve in the region through the at least one electrode contact; and blocking neural activity with the ENCB to reduce the pain or other unwanted sensation in the subject.

Treatment of pain using electrical nerve conduction block

One aspect of the present disclosure is a system including a waveform generator, a controller, and an electrical contact. The waveform generator is for generating an electrical nerve conduction block (ENCB). The controller is coupled with the waveform generator. The controller is configured to receive an input comprising at least one parameter to adjust the ENCB. The electrical contact is coupled with the waveform generator. The electrical contact is configured to be placed into contact with a nerve. The electrical contact comprises a high charge capacity material that prevents formation of damaging electro-chemical products at a charge delivered by the ENCB. The electrical contact is configured to deliver the ENCB to the nerve to block transmission of a signal related to a pain through the nerve.

Systems for treatment of a neurological disorder using electrical nerve conduction block

Described here are devices, systems, and methods for treating one or more conditions, such as allergic rhinitis, non-allergic rhinitis, nasal congestion, ocular allergy, and/or symptoms associated with these conditions, by providing stimulation to nasal or sinus tissue. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs, and the nasal insertion prongs may be configured to deliver an electrical stimulus to the tissue.

Nasal stimulation for rhinitis, nasal congestion, and ocular allergies

Described here are devices, systems, and methods for treating meibomian gland disease and/or blepharitis by providing intranasal stimulation. Generally, the devices may deliver electrical stimulation to the nasal mucosa. Intranasal stimulation may unblock obstructed meibomian glands and increase the lipid content of tears, both acutely during stimulation and subsequent to intranasal stimulation. The methods may include an initial round of stimulation to unblock obstructed meibomian glands, and subsequent shorter rounds of stimulation to cause meibum secretion and maintain the open glands.

The waveform generator is for generating an electrical nerve conduction block (ENCB). The controller is coupled with the waveform generator. The controller is configured to receive an input comprising at least one parameter to adjust the ENCB. The electrical contact is coupled with the wave-form generator. The electrical contact is configured to be placed into contact with a nerve. The electrical contact comprises a high charge capacity material that prevents formation of damaging electro-chemical products at a charge delivered by the ENCB. The electrical contact is configured to deliver the ENCB to the nerve to block transmission of a signal related to a pain through the nerve.

A medical device including an elongate member having a proximal end configured to be electrically coupled to an energy source, and a distal member disposed at a distal end of the elongate member. The distal member may include a plurality of contact elements configured to deliver stimulating energy to innervated tissue, detect a response from the innervated tissue to the stimulating energy, and deliver therapeutic energy to the innervated tissue based on the response from the innervated tissue.
