Method and apparatus for low frequency induction therapy for the treatment of urinary incontinence and overactive bladder
Current treatment options for Overactive Bladder and Urinary Incontinence include exercise and behavioral modifications, pharmacological therapies, surgical intervention, and neuromodulation. Although each of these treatments is used in the treatment of individuals with these conditions, each has severe limitations. Building on the limitations of existing therapies, and with the distillation of lessons learned from the field of pulsed electric stimulation, the present invention employs Low Frequency Induction Therapy for the delivery of an effective, cost efficient, noninvasive alternative to available treatment options. The device of the present application allows for consistent, user-friendly modulation of the pudendal nerve and the sacral plexus, via pulsed electromagnetic stimulation of the posterior tibial nerve, on an outpatient basis. The device has two primary components: a programmable Logic Controller (LC), which generates the required current, and a Conductive Wrap (CW), through which the current is channeled in generating the pulsed electromagnetic fields.
