System and method for electrical stimulation of anorectal structures to treat urinary dysfunction
First Claim
1. A device for improving a urinary sphincter function of a patient, comprising:
- a first electrode configured to contact a first tissue region, wherein said first tissue region is not in physical contact with an internal urinary sphincter of the patient;
a second electrode configured to contact a second tissue region, wherein said second tissue region not in physical contact with said internal urinary sphincter of the patient, wherein said second tissue region is separate and distinct from the first tissue region;
a waveform generator coupled to the first electrode and second electrode, wherein the waveform generator is configured to generate electrical pulses to the first electrode and second electrode and wherein said electrical pulses comprise a pulse width having a range of 10 μ
sec to 500 msec;
a pulse amplitude of 1 μ
Amp to 100 mAmp; and
a pulse frequency of 1 cpm to 100 Hz; and
wherein said pulse width, pulse amplitude, pulse frequency and duty cycle for the electrical pulses transmitted to the first electrode and second electrode are defined such that, after an application of said electrical pulses, an abdominal leak pressure increases by at least five percent relative to an abdominal leak pressure prior to said application of said electrical pulses or such that, after an application of said electrical pulses, an abdominal leak volume increases by at least five percent relative to an abdominal leak volume prior to said application of said electrical pulses.

Abstract
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.
