Patent number: 11779766Abstract: The present disclosure provides a medical stimulation system that includes a plurality of implantable channels each operable to obtain a voltage signal from a designated area of a body tissue. The medical stimulation system includes an impedance measurement device. The impedance measurement device includes a plurality of attenuators each coupled to a respective one of the channels. The attenuators are each operable to attenuate an amplitude of the voltage signal received from its respectively-coupled channel. The impedance measurement device includes a multiplexing component that receives the amplitude-attenuated voltage signals from each of the attenuators. The multiplexing component selectively outputs two of the amplitude-attenuated voltage signals. The impedance measurement device includes a differential amplifier that receives the two amplitude-attenuated voltage signals outputted from the multiplexing component as a differential input signal.Type: GrantFiled: May 6, 2019Date of Patent: October 10, 2023Assignee: CIRTEC MEDICAL CORP.Inventors: Stephen C.

Patent number: 11596792Abstract: A system, method, and apparatus for treating a medical condition by applying transcutaneous electrical stimulation to a target peripheral nerve of a subject. Electrical stimulation is applied to the peripheral nerve via a stimulation electrode pattern under closed-loop control in which EMG responses are monitored and used to adjust stimulation parameters. In response to detecting an unacceptable recording, electrical stimulation is applied to the peripheral nerve under open-loop control.Type: GrantFiled: August 20, 2021Date of Patent: March 7, 2023Assignee: AVATION MEDICAL, INC.Inventors: Alexandru Campean, Jeff A.
