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.

Methods and devices for improving pelvic floor dysfunction in a patient suffering therefrom by electrically modulating neural tissue in a minimally invasive fashion using an electrical micro stimulator are provided.

Devices, systems, and methods for identifying a target medical device implant

Methods, devices and systems for improving pelvic floor dysfunction in a patient suffering therefrom by electrically modulating neural tissue in a minimally invasive fashion using an electrical microstimulator are provided. Methods include inserting an electrical microstimulator having a re-deployable fixation member through skin of a patient's leg and advancing the electrical microstimulator through the skin along tissue of a surgical pathway to an area of the patient's leg. A target implant site can be identified that is above deep fascia and below the skin and that is adjacent to a target nerve associated with pelvic floor function. The electrical microstimulator can be anchored to the target implant site via the re-deployable fixation member or re-positioned, if necessary. A therapy electrical signal can be delivered to the target nerve from the target implant site.

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. The differential amplifier generates an amplifier output signal that includes at least partially an amplified version of the differential input signal.
