Abstract

Abstract Apparatus for treatment of spasticity by electrical stimulation in male and female patients having spinal cord injury. The apparatus is likewise adapted to stimulate ejaculatory nerves in the male through ejaculation and is characterized by an electronic stimulator which delivers current by rectal probe to the prostate and seminal vesicle glands in serial variance of since wave voltage. In both male and female treatment of spasticity, substantially similar apparatus is employed.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 160 words
Apparatus for reducing spacticity of neurologically impaired patients comprising: a) an elongated anal probe which is adapted to apply stimulus to a patient's pelvic floor, said probe defining a distal penetrating end and a proximal end, an axially aligned channel formed between ends therein with at least three conduits emanating radially therefrom, said probe further defining three longitudinally extending cavities therein, each said cavity being connected to one each of the conduits; three elongated bipolar electrodes, one each being secured in a corresponding cavity and extending above a ventral surface of the probe; b) a temperature sensor disposed within one said conduit adjacent one said bipolar electrode, interiorly of the probe; c) a stimulator circuit including the bipolar electrodes wherein current in the range of 0-35 volts and 0-700 milliamps may be delivered to the electrodes through the axially aligned channel and conduits alternately by AC or DC, to effect electrical stimulus to the patient whereby to reduce spacticity therein.
Claim 2
Dependent Claim 160 words
Apparatus for reducing spacticity of neurologically impaired patients comprising: a) an elongated anal probe which is adapted to apply stimulus to a patient's pelvic floor, said probe defining a distal penetrating end and a proximal end, an axially aligned channel formed between ends therein with at least three conduits emanating radially therefrom, said probe further defining three longitudinally extending cavities therein, each said cavity being connected to one each of the conduits; three elongated bipolar electrodes, one each being secured in a corresponding cavity and extending above a ventral surface of the probe; b) a temperature sensor disposed within one said conduit adjacent one said bipolar electrode, interiorly of the probe; c) a stimulator circuit including the bipolar electrodes wherein current in the range of 0-35 volts and 0-700 milliamps may be delivered to the electrodes through the axially aligned channel and conduits alternately by AC or DC, to effect electrical stimulus to the patient whereby to reduce spacticity therein.
Claim 3
Dependent Claim 16 words
The apparatus of claim 1 wherein the current is in a 60 Hz sine wave pattern.
