A system and method for treating anorectal and/or genitourinary dysfunction includes implanting, in a minimally invasive manner, an electro-medical device for stimulation of two or more anatomical or histological structures of the anorectal region and/or genitourinary region. Electrodes operably connected to the device are positioned proximate the target anatomical or histological structures. The device provides either the same or different stimulation algorithms to each anatomical or histological structure, which may be the same or different. The varied stimulation parameters, such as pulse width, pulse amplitude, and pulse frequency, are defined such that after an application of the electrical pulses, an abdominal leak pressure, an abdominal leak volume, or a urine volume increases or a number of incontinent episodes or a mean incontinence volume per episode decreases relative to said parameters prior to the application of the electrical pulses.

Distributed electrode lead configurations for providing electrical therapy, and associated systems and methods. A representative patient therapy system includes at least one implantable signal delivery device having a proximal portion and a distal portion. The proximal portion is configured to be coupled with an implantable pulse generator to direct a pulsed electrical signal at a frequency from about 1.5 kHz to about 100 kHz. The distal portion includes multiple electrical contacts for delivering the pulsed electrical signal to a target neural population of a patient when implanted. At least three neighboring electrical contacts of the multiple electrical contacts are electrically connected together and have equal lengths less than 3 mm. The at least three neighboring electrical contacts are uniformly spaced apart by a distance from about 1 mm to about 8 mm.

In various embodiments methods and devices are provided for regulating bladder function in a subject after a spinal cord and/or brain injury. In certain embodiments the methods comprise applying a pattern of electrical stimulation to the Lumbosacral spinal cord at a frequency and intensity sufficient to initiate micturition and/or to improve the amount of bladder emptying. In certain embodiments the electrical stimulation is at a frequency and intensity sufficient to improve the amount of bladder emptying (e.g., to provide at least 30% emptying or at least 40% emptying, or at least 50% emptying, or at least 60% emptying, or at least 70% emptying, or at least 80% emptying, or at least 90% emptying, or at least 95% emptying.

The disclosure relates to an electrical stimulation therapy method. The method includes applying a variable frequency stimulation pulse to target nerve tissue of the patient suffering from dysfunction of a nerve circuit in the brain selected from the group consisting of motor circuit, associative circuit and limbic circuit, wherein the variable frequency stimulation pulse comprises at least two kinds of electrical stimulation pulse trains at different frequencies; and each of the at least two kinds of alternate electrical stimulation pulse trains in each of the plurality of pulse train periods has a duration in a range from about 0.1 seconds to about 60 minutes. The target nerve tissue is a part of the nerve circuit. The different frequencies of the electrical stimulation pulse trains are in a range from about 10 Hz to about 250 Hz.

Methods and systems for providing neuromodulation therapy are disclosed. The methods and systems are configured to sense an evoked neural response and use the evoked neural response as feedback for providing neuromodulation therapy. Methods of reducing stimulation artifacts that obscure the sensed evoked neural response are disclosed. The methods of artifact reduction include recording a stimulation artifact in the absence of an evoked neural response, aligning and scaling the stimulation artifact with respect to the obscured signal, and subtracting the aligned and scaled artifact from the obscured signal.

In some examples, a technique for delivering electrical stimulation therapy to a patient includes determining, by processing circuitry, one or more cycle settings associated with delivery of the electrical stimulation therapy, determining, by the processing circuitry, a cycle time period associated with each cycle setting, and delivering, by a medical device, electrical stimulation therapy based on the determined cycle settings and the determined cycle time periods. Each cycle setting may define an on-cycle, during which electrical stimulation is delivered, and an off-cycle, during which electrical stimulation is not delivered. The technique further may include delivering electrical stimulation to the patient to provide one or more reminders to the patient, such as a reminder to void or a reminder of the existence of electrical stimulation.

A medical device provides stimulation therapy to a patient based on a set of therapy parameters. One or more therapy parameters may be automatically adjusted based on acceleration forces detected by a sensor, the acceleration forces being applied to the patient. In some examples, adjustments to one or more therapy parameter may be made based on an algorithm. The algorithm may be defined by acceleration and therapy parameter value pairs associated with opposite patient positions.

Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.

A pulse current generation circuit (100) for neural stimulation includes an analogue signal receiving device (101) for receiving an analogue signal; an analogue-to-digital converter (102) for converting the analogue signal into a digital control signal; a current signal controller (103) for producing, according to the digital control signal, pulse current parameters for generating bidirectional pulse current signals; and a current generator (104) for generating, according to the pulse current parameters, bidirectional pulse current signals for neural stimulation, and the current generator can generate pulse currents of different precisions according to the pulse current parameters.
