Publication number: 20230233848Abstract: Chronic pain management can be achieved by electrically anesthetizing a peripheral nerve with on-demand electrical nerve block (OD-ENB). OD-ENB can be provided by an implantable capsule. Externally, at least a portion of the capsule can be constructed of a conductive membrane and the rest of the capsule comprises a biocompatible material. A blocking electrode contact, a return electrode contact, and a powering/communication component can be within the capsule. The blocking electrode contact can deliver a direct current (DC) through a portion of the conductive membrane to block conduction in the neural tissue to provide the OD-ENB. The return electrode contact can receive a return current from the neural tissue through another portion of the conductive membrane. The powering/communication component can communicate with one or more external components located external to the patient's body to receive a power signal. Notably the capsule has no internal battery.Type: ApplicationFiled: April 3, 2023Publication date: July 27, 2023Inventors: Tina L. Vrabec, Kevin L. Kilgore, Jesse S. Wainright, Niloy Bhadra

Publication number: 20220168563Abstract: Accelerated recovery from direct current (DC) nerve block can be achieved using repolarization. A direct current (DC) waveform can be applied to a nerve for a time sufficient to achieve nerve block. The DC waveform can be switched to another DC waveform of reversed polarity, which can be applied for a second time, causing the nerve to enter a repolarization cycle to accelerate recovery time for the nerve. Moreover, simply applying a subthreshold DC waveform to the nerve for a time by itself can enhance a response of the nerve without blocking conduction in the nerve.Type: ApplicationFiled: March 13, 2020Publication date: June 2, 2022Inventors: Tina L.

Patent number: 11191974Abstract: A capacity-expanding separated interface nerve electrode (SINE) can be used to deliver a nerve conduction block to one or more nerves. The SINE can include a source electrode coupled to a waveform generator. The source electrode can deliver an electrical neuromodulation signal (e.g., a direct current (DC) signal) to an ionically conductive medium. The SINE can also include a vessel holding the ionically conductive medium, which can include a material that facilitates a transformation of the electrical neuromodulation signal to an ionic neuromodulation signal with a high charge capacity. The SINE can also include a nerve interface that can deliver the ionic neuromodulation signal to a nerve. The SINE can be used in combination with a return electrode that is also coupled to the waveform generator.Type: GrantFiled: May 24, 2018Date of Patent: December 7, 2021Assignee: CASE WESTERN RESERVE UNIVERSITYInventors: Tina L.

Patent number: 8247135Abstract: The invention is a flexible, micro-fabricated fuel cell and fuel cell stack that can be helically wound or bend into cylindrical shapes. The electrolyte is a proton exchange membrane (PEM) upon which can be printed, by ink jet means, the anode and cathode electrodes and the current collectors that convey current to or from the edges of the PEM which has a thickness on the order of 0.001 to 0.010 inch. Pluralities of the series connected fuel cell stacks can be arranged in electrical and physical parallel with one another to provide what are batteries of fuel cell stacks that can be connected by manifolds to sources of fuel and oxidizer. The invention is directed to a thin, light-weight, flexible fuel cell assembly that can be produced in ambient conditions using standard micro-fabrication techniques, such as thick film printing and ink jet deposition. Thick film printing techniques, screen printing or ink jet printing, are used to deposit porous current collectors on either side of the membrane.Type: GrantFiled: September 14, 2005Date of Patent: August 21, 2012Assignee: Case Western Reserve UniversityInventors: Jesse S.
