Publication number: 20230239005Abstract: Described herein are methods of making and using and apparatus for wirelessly communicating data and providing power, particularly from a location exterior to a body and to an implantable device disposed within a body with tissue. The described embodiments provide apparatus and methods for efficiently transfer data and power between an external transceiver and an (implanted) biomedical device. The method is to modulate power carrier, which wirelessly powers the device, using an asynchronous modulation scheme, such as amplitude shift keying (ASK) modulation, with minimal modulation depth in order to not disrupt the power flow. The digital data is encoded in the pulse width, eliminating the need for synchronization to the power carrier signal and further minimizing the power consumption necessary for data transfer. Additionally, a reverse backscatter method for obtaining data from the implant is described that has flexible, low power operation.Type: ApplicationFiled: August 23, 2022Publication date: July 27, 2023Inventors: Anatoly Anatolievich Yakovlev, Daniel Pivonka, Ada Shuk Yan Poon, Teresa H.

Patent number: 11633151Abstract: A medical apparatus configured to neuromodulate tissue and/or record patient information is provided. The apparatus includes an external system to transmit transmission signal(s), each signal having at least power or data, and an implantable system to receive the transmission signal(s). The data transfer between the external and implantable systems is asynchronous. The external system includes external antenna(s) to transmit a transmission signal. The transmission signal is an amplitude modulated signal modulated by varying a load on the external antenna(s) that causes an impedance mismatch prior to amplifying the signal for transmission. An implantable device includes implantable antenna(s) to receive the transmission signal. The implantable system comprises a receiver to receive the transmission signal from the implantable antenna(s), implantable transmission module(s) to transmit data to the external system, and a variable load connected to the implantable antenna(s).Type: GrantFiled: February 4, 2019Date of Patent: April 25, 2023Assignee: Nalu Medical, Inc.Inventors: Daniel Pivonka, Anatoly Yakovlev
