Embodiment Construction

[0265] This specification relates to programmable implantable electromedical devices for the treatment of various anorectal or genitourinary neuromuscular abnormalities, including fecal incontinence, constipation, urinary incontinence, and sexual dysfunction. The electromedical devices of the present specification employ implantable microstimulators or macrostimulators that can be implanted in the anorectal and / or urogenital regions with minimal invasiveness. 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 electromedical device includes a common anode or cathode in the middle and two separate electrodes at each end, each having an opposite polarity to the central electrode. In another embodiment, the device has only two electrodes, wherein the stimulating electrodes are selected based on the desired area to be stimulated. In various embodiments, the e...

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 orhistological structures of the anorectal region and / or genitourinary region. Electrodes operably connected to the device are positioned proximate the target anatomical or histological structures. Thedevice 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 anumber of incontinent episodes or a mean incontinence volume per episode decreases relative to said parameters prior to the application of the electrical pulses.
