Patent number: 11951316Abstract: Apparatus for use with a medical implant having a receiving coil. A flexible housing to be placed against skin of a subject includes a flexible transmitting coil and control circuitry for driving a current through the transmitting coil to induce a current in the receiving coil. A sensor coupled to the circuitry determines divergence of a resonance frequency of the transmitting coil when flexed from a nominal resonance frequency of the transmitting coil, occurring in the absence of any forces applied to the transmitting coil. One or more electrical components coupled to the circuitry tune the resonance frequency of the transmitting coil. A switch is coupled to each of the electrical components, the switches including transistors having capacitances that depend on the voltage applied to each switch. The circuitry applies a respective DC voltage to each switch. Other applications are also described.Type: GrantFiled: December 9, 2021Date of Patent: April 9, 2024Assignee: BLUEWIND MEDICAL LTD.Inventors: Gur Oron, Anton Plotkin, Eran Benjamin, Alexander Firtel, Amiel Greenberg, Yigal Elisha

Publication number: 20230170138Abstract: A housing placeable against skin of a subject includes a transmitting coil. Battery-powered control circuitry including a power stage transmits power to an implant by activating the power stage to drive a current through the transmitting coil to induce an induced current in a receiving coil of the implant. A sensor indicates divergence of a real-time resonance frequency of the transmitting coil with respect to a reference resonance frequency of the transmitting coil at which (a) efficiency of the power stage is at least 70% of a maximum efficiency as a function of the resonance frequency, and (b) the current driven through the transmitting coil is less than 960 of a maximum current drivable through the transmitting coil as a function of the resonance frequency. The circuitry reduces the divergence by tuning the resonance frequency of the transmitting coil. Other applications are also described.Type: ApplicationFiled: November 22, 2022Publication date: June 1, 2023Applicant: BLUEWIND MEDICAL LTD.Inventors: Gur ORON, Anton PLOTKIN, Eran BENJAMIN, Alexander FIRTEL, Amiel GREENBERG, Yigal ELISHA

Publication number: 20220355120Abstract: Power is transmitted to an implanted receiving coil oriented such that an axis of the receiving coil is parallel to skin of a subject. A transmitting coil is in a housing, which is placed against the skin. A central axis of the transmitting coil is perpendicular to the skin. A portion of the transmitting coil is over the receiving coil. A first distance, from the axis of the transmitting coil to a center of the receiving coil, is greater than a second distance, from the axis of the transmitting coil to an inner edge of the portion of the transmitting coil. The first distance is less than a third distance, from the axis of the transmitting coil to an outer edge of the portion of the transmitting coil. Circuitry powers the implant by driving current through the transmitting coil that induces current in the receiving coil.Type: ApplicationFiled: July 25, 2022Publication date: November 10, 2022Applicant: BLUEWIND MEDICAL LTD.Inventors: Gur ORON, Anton PLOTKIN, Eran BENJAMIN, Alexander FIRTEL, Amiel GREENBERG, Yigal ELISHA
