Definitions

• TECHNICAL FIELD This invention relates to apparatus for applying electrical energy to living tissue. More particularly, the present invention relates to apparatus for electrically stimulating penile, scrotal, anal, vaginal, and clitoral tissue. In a further and more specific aspect, the invention relates to electrically stimulating penile, scrotal, vaginal, and clitoral tissue for the purposes of treating incontinence in men and women, inducing penile erection, and inducing male and female orgasm.
• Rigid rings capable of transmitting low levels of electricity to the skin and muscles are typically applied about the penis and/or the scrotum.
• Insertable rolled or plug-type electrodes made to be rolled to size or sized in a variety of sizes to fit the user's anatomy, are known for the purpose of applying low levels of electricity to the skin and muscles inside and surrounding the vagina and the anus.
• Urinary incontinence is a common problem that may require long term retraining of self-control, particularly after a . stroke, or permanent use of an external control device.
• the prior art does not teach an apparatus that is designed to be worn while the user, fully dressed, moves about his or her everyday course of events.
• Rigid rings are useable for males where the application of electrical current to only a portion of penile tissue is sufficient to induce urethral control or erection. This is because sufficient expansion room is required within the ring to accommodate penile engorgement.
• Rigid rings are particularly problematic where penile atrophy has occurred, and the desired goal is erection or orgasm. The tremendously varying size of the penile tissue from rest to engorgement may cause a need to use a large diameter ring on a small diameter penis, or to change rings during a treatment.
• a discrete unit usable in a variety of ways, is desirable to control incontinence or to stimulate and to induce orgasm.
• Such a unit should be particularly designed to be worn under a user's clothing, and operative while the female is engaged in normal everyday activity.
• Another object of the invention is the provision of improvements especially adapted for use in connection with apparatus for controlling and treating incontinence in men and women.
• Another object of the invention is to provide improved means for the application of electrical stimulation to the vagina. Still another object of the immediate invention is the provision of an improved means for the application of electrical stimulation to the vagina that can be easily adapted for the application of electrical stimulation to the clitoral tissue.
• Yet another object of the invention is to provide means for the application of electrical stimulation to the penile and scrotal tissue.
• Yet still another object of the invention is the provision of improved means for the application of electrical stimulation to the penile and scrotal tissue that can expand with penile erection.
• a further object of the instant invention is to provide improvements in the connectivity of electrical stimulation apparatus.
• a further object of the invention is the provision of a male and female electrical stimulation apparatus that can be worn comfortably and discretely under a user's clothing.
• Yet a further object of this invention is to provide male electrical stimulation apparatus that can induce erection and orgasm, and female electrical stimulation apparatus that can induce orgasm.

• memory bend wire 169 can also serve as the electrical connection between tip 166 and first connector 163.
• a separate wire may be utilized along with an insulated memory bend wire 169.
• memory bend wire 169 enables electrode 160 to maintain its shape after being manipulated by a user.
• FIG. 19 illustrates a cross-sectional view of an alternate embodiment of a vaginal electrode 170 formed from the same elastomeric materials and in the same manner as taught herein. Electrode 170 has a nonconductive base 171, through which connectors 172 and 173 are mounted.
• Connector 172 is mounted to be in direct contact with conductive portion 174, whereas connector 173 is shielded from conductive portion 174.
• Nonconductive portion 176 is configured as a stripe that runs around the circumference of electrode 170.
• Conductive portion 174 is located on one side of nonconductive portion 176, and conductive portion 175 is located on the other side of nonconductive portion 176.
• Shielded wire 177 which is run through conductive portion 174 as electrode 170 is formed, has a first nonshielded end connected to connector 173.
• Wire 177 has unshielded end 178 which feeds current to conductive portion 175.
• the two conductive portions of vaginal electrode 170 can be wired to one connector instead of two, by simply running the first unshielded portion of wire 177 connected to connector 173 into conductive portion 174. In this way, electrode 170 can be used with another single connector electrode.
• electrode 170 may include an elastomeric conductive rod enclosed within a nonconductive channel or surrounded by nonconductive material. Forming a conductive portion within electrode 170 may be desirable to lower manufacturing costs.
• a memory bend wire 179 is preferably located within electrode 170 to enable a user to adjust the shape of electrode 170. As described above, memory bend wire 179 is preferably shielded such that conductive portions 174 and 175 remain insulated from one another. None prevents wire 177 from being incorporated with memory bend wire 179 into a single assembly.
• Anal electrode 180 is formed from the same elastomeric materials as taught herein and is shown in FIG. 20. It has base 181, connectors 182 and 183 mounted through base 181, nonconductive portion 184, and conductive portions 186 and 187. Nonconductive portion 184 defines a nonconductive volume that extends from base 181 to and including the point of eiectrode 180. As described above, connectors 182 and 183 are preferably in direct physical and electrical contact with conductive portions 187 and 186, respectively. Anal electrode 180 has a wider portion 185, and a narrower portion 188. This allows electrode 180 to be held easily within the anal cavity when in use to control incontinence or for sexual purposes.
• Anal electrode 180 preferably includes a memory bend wire 189 located therein.
• Memory bend wire 189 functions as described above in connection with electrodes 50, 160, and 170 (see respective FIGS. 2 , 18, and 19). If memory bend wire 189 is located wholly within nonconductive portion 184, then it need not be electrically insulated. '
• FIG. 21 shows an electrode 190 which can be used within the anal cavity or can be sized to fit inside the male urethral cavity.
• Electrode 190 which is preferably formed from the same elastomeric materials as taught herein, has nonconductive base 191 and connector 192 mounted through base 191 and in direct contact with conductive portion 193. Electrode 190 is intended for use with another single connector electrode like ring 100.
• Using electrode 190 for urethral stimulation while also using a single connector embodiment of electrode 180 in the anal cavity provides for an extremely efficient method of controlling male incontinence. Electrical stimulation is applied directly to the areas, as well as through the body where urethral control muscles are located. This causes them to contract thereby closing off the path to the bladder.
• Electrode 190 also includes a memory bend wire 194 located therein.
• Memory bend wires are described above for various embodiments of the present invention.
• Memory bend wire 194 allows electrode 190 to maintain its shape after manipulation by a user.
