Abstract
Abstract An electrostimulation probe comprising a suppository b0dy formed with a rounded bulbous head, a reduced neck, and a broadened hilt, is inserted into the anus of a patient suffering from incontinence. The rounded bulbous tip and reduced neck facilitate anal insertion and subsequent retention. The rounded neck is clasped by the sphincter rectalis, and is provided with a pair of spaced electrical contacts which rest against the sphincter. The broadened hilt limits insertion of the suppository body, and has a substantially flat base so as to permit the patient to set or lie down confortably with the device inserted. A pair of electrical leads are connected respectively to the contacts, which are energized by a square wave signal having an average value of zero Volts, a peak potential between 1 and 2 Volts, and in the frequency range from about 18 to about 20 Hertz. Such electrostimulation causes tonic and physiological contraction of the sphincter muscle, with significant results in the control of incontinence.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
173 words
A suppository electrode structure for use in controlling incontinence, comprising: a suppository body formed of an insulating material and including a rounded bulbous tip adapted for insertion into and subsequent retention within the anus of a patient, a reduced neck joined to one end to said bulbous tip, and a broadened hilt joined to said reduced neck at the other end thereof to limit anal insertion of said suppository device so that said reduced neCk rests against the sphincter rectalis; and a pair of elongated substantially coextensive circumferentially spaced-apart electrical contacts extending longitudinally along substantially the full length of said neck and energizable by an external voltage source and secured to the external surface of said reduced neck whereby to rest against said sphincter rectalis during insertion, the end of said broadened hilt opposite to said reduced neck being substantially flat to permit said patient to sit and lie down comfortably when said suppository body is inserted, said suppository body being formed of silicone rubber and said electrical contacts being formed of gold.
Claim 2
Dependent Claim
173 words
A suppository electrode structure for use in controlling incontinence, comprising: a suppository body formed of an insulating material and including a rounded bulbous tip adapted for insertion into and subsequent retention within the anus of a patient, a reduced neck joined to one end to said bulbous tip, and a broadened hilt joined to said reduced neck at the other end thereof to limit anal insertion of said suppository device so that said reduced neCk rests against the sphincter rectalis; and a pair of elongated substantially coextensive circumferentially spaced-apart electrical contacts extending longitudinally along substantially the full length of said neck and energizable by an external voltage source and secured to the external surface of said reduced neck whereby to rest against said sphincter rectalis during insertion, the end of said broadened hilt opposite to said reduced neck being substantially flat to permit said patient to sit and lie down comfortably when said suppository body is inserted, said suppository body being formed of silicone rubber and said electrical contacts being formed of gold.
Claim 3
Dependent Claim
148 words
A suppository electrode structure for use in controlling incontinence, comprising: a suppository body formed of an insulating mater-al and including a rounded bulbous tip adapted for insertion into and subsequent retention within the anus of a patient, a reduced neck joined at one end to said bulbous tip, and a broadened hilt joined to said reduced neck at the other end thereof to limit anal insertion of said suppository device so that said reduced neck rests against the sphincter rectalis; and a pair of elongated substantially coextensive circumferentially spaced-apart electrical contacts extending longitudinally along substantially the full length of said neck and energizable by an external voltage source and secured to the external surface of said reduced neck whereby to rest against said sphincter rectalis during insertion; a pair of electrical leads for connection to said external voltage source and connected to said contacts respectively for energization thereof.
Claim 4
Dependent Claim
148 words
A suppository electrode structure for use in controlling incontinence, comprising: a suppository body formed of an insulating mater-al and including a rounded bulbous tip adapted for insertion into and subsequent retention within the anus of a patient, a reduced neck joined at one end to said bulbous tip, and a broadened hilt joined to said reduced neck at the other end thereof to limit anal insertion of said suppository device so that said reduced neck rests against the sphincter rectalis; and a pair of elongated substantially coextensive circumferentially spaced-apart electrical contacts extending longitudinally along substantially the full length of said neck and energizable by an external voltage source and secured to the external surface of said reduced neck whereby to rest against said sphincter rectalis during insertion; a pair of electrical leads for connection to said external voltage source and connected to said contacts respectively for energization thereof.
Claim 5
Dependent Claim
21 words
The suppository electrode structure of claim 2 in combination with an electrical generator connected to said leads for energizing said contacts.
