The disclosed electrical stimulation system generates interventions to assist patients in complying with a diet. The wearable device includes a microprocessor, electrical stimulator and at least one electrode configured to deliver electrical stimulation to the epidermis, through a range of 0.1 mm to 10 mm or a range of 0.1 mm to 20 mm of the dermis, of a T2 dermatome to a T12 dermatome or meridian of the patient, a C5 to a T1 dermatome across the hand and/or arm, and/or the upper chest regions. The device is adapted to provide electrical stimulation as per stimulation protocols and to communicate wirelessly with a companion control device configured to monitor and record appetite patterns of the patient and deliver titrated therapy. The control device is also configured to monitor, record, and modify stimulation parameters of the stimulation protocols.

Systems, devices, methods, and techniques are described for phase misalignment correction for evoked compound action potential (ECAP) measurement from alternating polarity stimulation. An example system includes processing circuitry that receives a first ECAP signal elicited by a first polarity configuration of stimulus electrodes and receives a second ECAP signal elicited by a second polarity configuration of the stimulus electrodes opposite the first polarity configuration. The processing circuitry also generates an adjusted second ECAP signal by temporally aligning at least a portion of the second ECAP signal to at least a portion of the first ECAP signal, and generates a composite ECAP signal based on the first ECAP signal and the adjusted second ECAP signal. Additionally, the processing circuitry outputs the composite ECAP signal.

Provided herein as a transoral minimally invasive method and a system thereof for the treatment of gastrointestinal diseases and/or obesity, which at least partially encircles a part of the gastrointestinal tract, such as esophagus of the patient by advancing an elongated deformable portion of a neurostimulator assembly endoluminally to the subfascial area from the outer wall of the esophagus and introducing the elongated deformable portion sub-fascially in the subfascial area, whereby at least one part of the encircled esophagus will be modulated using a modulator.

Disclosed is a device for modulating a nerve of a patient by applying electrical stimulation to the nerve of the patient. The device includes a stimulation module that applies a signal to the nerve of the patient, and a controller that controls a signal to be applied to the stimulation module, wherein the signal to be applied to the stimulation module includes pulse bursts and a direct current (DC) waveform.

The present application relates to a new stimulation design which can be utilized to treat neurological conditions. The stimulation system produces a burst mode stimulation which alters the neuronal activity of the predetermined site, thereby treating the neurological condition or disorder. The burst stimulus comprises a plurality of groups of spike pulses having a maximum inter-spike interval of 100 milliseconds. The burst stimulus is separated by a substantially quiescent period of time between the plurality of groups of spike pulses. This inter-group interval may comprise a minimum of 5 seconds.
