Abstract
Systems and Methods treat bladder dysfunctions using neuromodulation stimulation. Bladder emptying through stimulation of urethral afferents, and continence through stimulation of the dorsal genital nerve, is provided with one or more implanted pulse generators and one or more leads. A simple surgical procedure preserves all existing functions. A stimulating catheter is provided to be used as a clinical screening tool. The stimulating catheter is used to measure bladder pressures and stimulate the urethra at the same time.

49. A method of providing bladder function comprising:
-
providing a first lead including one or more stimulation electrodes, providing a second lead including one or more stimulation electrodes, positioning the first lead on, in, or near a dorsal genital nerve, positioning the second lead on in, or near urethral afferents, applying a stimulation pulse to the first lead and to the second lead to provide bladder function. - View Dependent Claims (50, 51)

52. A method of improving bladder function comprising:
-
providing a first elongated lead comprising one or more stimulation electrodes sized and configured to be implanted in a tissue region at or near a target A, providing a second elongated lead comprising one or more stimulation electrodes sized and configured to be implanted in a tissue region at or near a target B, providing a pulse generator to convey one or more electrical stimulation waveforms to the first lead to stimulate the target A and to the second lead to stimulate the target B, implanting the first lead in the tissue region at or near the target A, implanting the second lead in the tissue region at or near the target B, coupling the first lead and the second lead to the pulse generator, operating the pulse generator to convey one or more electrical stimulation waveforms to the first lead to stimulate the target A, the stimulation waveforms conveyed to the stimulation electrodes affecting afferent stimulation of target A, operating the pulse generator to convey one or more electrical stimulation waveforms to the second lead to stimulate the target B, the stimulation waveforms conveyed to the stimulation electrodes affecting afferent stimulation of target B, and the afferent stimulation activating central nervous system circuitry that coordinates and/or produces efferent activity in target A and/or efferent activity in target B to produce and/or further continence and/or bladder emptying.

58. A method of restoring bladder function comprising:
-
implanting a first lead adapted for dorsal genital nerve stimulation, implanting a second lead adapted for urethral afferent stimulation, coupling the first lead to a pulse generator, coupling the second lead to the pulse generator, operating the pulse generator in a continence mode to allow the bladder to fill, and after the bladder has filled to a level, operating the pulse generator in a micturition mode to empty some or all of the contents of the bladder.

59. A system for restoring bladder function comprising:
-
a first lead adapted for dorsal genital nerve stimulation, a second lead adapted for urethral afferent stimulation, a pulse generator adapted to couple to the first lead and the second lead to provide electrical stimulation to the dorsal genital nerve and the urethral afferents, the pulse generator including a continence mode to allow the bladder to fill, and the pulse generator including a micturition mode to empty some or all of the contents of the bladder after the bladder has filled to a level.
