A system and methods utilizing electrical stimulation to achieve a desired therapeutic effect are provided. In one aspect, a method for controlling nerve activity in a subject is provided. The method includes receiving input indicating a desired therapeutic effect for at least one neural structure of a subject, and selecting, based on the input received, an electrical stimulation configured to achieve the desired therapeutic effect. The method also includes controlling a sympathetic nerve activity in the subject by delivering the electrical stimulation using electrodes positioned proximate to nerves innervating the subject's skin.

An electrical stimulation system includes a stimulator having at least one electrode and a power supply. The electrode is connectable to the power supply, and the power supply delivers electrical stimulation energy in the form of a capacitive discharge voltage through the stimulator and electrode to tissue proximate a target anatomy to induce an observable response in the target anatomy during a medical procedure.

A method to apply a nerve inhibiting cloud surrounding a blood vessel includes creating a treatment plan, wherein the treatment plan prescribes application of the nerve inhibiting cloud towards at least a majority portion of a circumference of a blood vessel wall, and applying the nerve inhibiting cloud towards the majority portion of the circumference of the blood vessel wall for a time sufficient to inhibit a function of a nerve that surrounds the blood vessel wall.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration. A system and method for fusing independent measures of the physiological parameters, in some examples using a Kalman filter for each possible combination of sensor measurements.

A biological information measurement device which is capable of improving accuracy of detection of optimal exercise intensity, a biological information measurement method, and a biological information measurement program are provided. At the biological information measurement device, heart rate counting means measures an HR value indicating a heart rate on the basis of heart-rate data obtained by capturing heartbeats when a subject to be measured exercises, and analysis means performs power spectrum analysis on a heart rate variability frequency of the heart-rate data to calculate an LF value which is an integral value of low frequency components. Detection means then detects an HR/LF value by dividing the HR value with respect to exercise intensity of the subject to be measured by an LF value. Thus, by the biological information measurement device obtaining the HR/LF value as a new index indicating sympathetic nerve activity, it is possible to obtain biological information important for health management.

Disclosed are methods and systems for treating epilepsy by stimulating a main trunk of a vagus nerve, or a left vagus nerve, when the patient has had no seizure or a seizure that is not characterized by cardiac changes such as an increase in heart rate, and stimulating a cardiac branch of a vagus nerve, or a right vagus nerve, when the patient has had a seizure characterized by cardiac changes such as a heart rate increase.

A nervous tissue imaging system and a method therefor. The system includes: a housing containing an excitation light source, optically coupled with a source optical train, the excitation light source emits excitation light in a first wavelength range, which can be in a near ultraviolet light range, to illuminate a tissue region of interest including healthy nervous tissue and healthy non-nervous tissue. The excitation light in the first wavelength range causes the healthy nervous tissue, in response to being illuminated with the excitation light, to endogenously autoflouresce and emit first autofluorescence light at a first luminance in a second wavelength range. The healthy non-nervous tissue, in response to being illuminated with the excitation light, either avoids emitting any autofluorescence light in the second wavelength range; or endogenously autoflouresces and emits second autofluorescence light in the second wavelength range at a second luminance that is lower than the first luminance.

Example devices, systems, and techniques predict renal denervation efficacy for reducing hypertension in a patient based on pulse information. For example, a system may include processing circuitry configured to obtain pulse information representative of pulses from both wrists of a patient, obtain a plurality of values representative of respective patient metrics for the patient, and apply the pulse information and the plurality of values to a deep learning model trained to represent a relationship of the pulse information and the patient metrics to an efficacy of renal denervation in reducing hypertension. In some examples, responsive to applying the pulse information and the plurality of values to the deep learning model, the processing circuitry obtains, from the deep learning model, a score indicative of renal denervation efficacy in reducing hypertension for the patient, and generates a graphical user interface comprising a graphical representation of the score for the patient.

The present invention relates to endotracheal tubes for intra-operative monitoring of nerve and muscle tissue (neuromonitoring), a system for intra-operative neuromonitoring, a method for deriving stimulus responses in intra-operative neuromonitoring, and a method for classifying tissue types, having the purpose of preventing damage to nerves and muscles which run within the area of operation.
