Electrical stimulation adjunct (Add-ON) therapy for urinary incontinence and urological disorders using implanted lead stimulus-receiver and an external pulse generator
First Claim
1. A method of delivering electrical pulses to sacral nerves and/or its branches, comprising the steps of:
- providing an external pulse generator means for generating and transmitting modulated high frequency pulses, wherein said external pulse generator means comprises a primary coil, power supply, memory, circuitry to emit electrical pulses, and at least two predetermined programs to control said electrical pulses wherein at least one of the programs may be locked out to the patient;
providing an implanted lead stimulus-receiver means for receiving, processing and delivering said pulses to said sacral nerves comprising electrical circuitry, replenishable or rechargeble power source, secondary coil, and at least one electrode adapted to be in contact with said sacral nerves and/or branches;
activating one of said at least two predetermined programs of said external stimulator to emit said electrical pulses to said primary coil; and
inductively transferring said electrical pulses from said primary coil of said external stimulator to said secondary coil of said lead stimulus receiver means;
whereby, said electrical pulses are delivered to said sacral nerves and/or its branches.

Abstract
A method and system for neuromodulation therapy for urinary incontinence and urological disorders comprises an implantable lead stimulus-receiver, and an external stimulator-transmitter having a power source, controlling circuitry, and predetermined programs. The stimulator-transmitter further includes a primary coil which inductively transfers electrical signals to the lead-receiver, which is also in electric contact with the sacral nerves. The external stimulator-transmitter emits electrical pulses to stimulate the sacral plexus according to a predetermined program. In one mode of operation, the operator may program one of the predetermined programs, in another mode, the electrical parameters may be “custom” programmed for the patient, and stored in the memory.

17. A method to selectively stimulate a sacral nerve and/or its branches, comprising the steps of:
-
providing an external pulse generator-transmitter means comprising circuitry to emit electrical signals, memory, a power supply, at least two predetermined programs, a primary coil, and telecommunications module for remote communication; providing an implantable stimulus-receiving means comprising a secondary coil, circuitry, replenishable or rechargeable power source, and at least one electrode adapted to be in contact with said sacral nerve and/or its branches; activating one of said at least two predetermined programs of said external pulse generator-transmitter to emit said electrical signals to said primary coil; and inductively transferring said electrical signals from said external coil of said external generator to said secondary coil of said stimulus-receiver, whereby said electrical signals selectively stimulate said sacral nerve and/or its branches. - View Dependent Claims (18, 19, 20, 21)
