Embodiment Construction

[0195] This specification relates to a programmable, implantable electrotherapy device for the treatment of various anorectal or genitourinary neuromuscular disorders, including fecal incontinence, constipation, urinary incontinence and sexual dysfunction. The electrotherapeutic device of the present specification employs an implantable micro stimulator or a macro stimulator that can be implanted with minimal invasiveness in the anorectal and / or genitourinary area. In one embodiment, each microstimulator includes at least two electrodes for delivering electrical stimulation to at least two separate target tissues. In one embodiment, the electrotherapeutic device includes a common anode or cathode in the middle and two individual electrodes at each end, each individual electrode having an opposite polarity to the central electrode. In another embodiment, the device has only two electrodes, where the stimulation electrode is selected based on the area that needs to be stimulated...

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.

Description

[0001] cross reference [0002] This application is a continuation-in-part of U.S. Patent Application No. 14 / 201,659, filed March 7, 2014, which is a continuation-in-part of U.S. Patent Application No. 13 / 400,868, filed February 21, 2012 and issued as U.S. Patent No. 8,706,234. This application also relies on the priority of US Patent Provisional Application No. 62 / 136,389, filed March 20, 2015. All of the above patent applications are incorporated herein by reference. technical field [0003] The present specification generally relates to methods and devices for electrical stimulation of the gastrointestinal tract. More particularly, the present specification relates to methods and devices for treating anal dysfunction by electrically stimulating the submucosa or muscularis muscularis or muscularis propria of the rectum or anal sphincter. The present specification also relates to methods and devices for treating voiding dysfunction by electrically stimulating the submucosa...
