Methods for stimulating components in, on, or near the pudendal nerve or its branches to achieve selective physiologic responses
View Patent ↗Systems and methods control physiological functions of the urinary tract using at least one electrode sized and configured to be located on, in, or near a targeted component of the pudendal nerve. The systems and methods apply an electrical signal to the electrode at a selected frequency to stimulate the targeted component. The selected frequency is a first frequency or range of frequencies for achieving a first physiologic response (e.g., controlling urinary continence) and a second frequency or range of frequencies, different than the first frequency, for achieving a second physiologic response different than the first physiologic response (e.g., controlling micturition).
1. A method for controlling a physiological function comprising
placing at least one electrode on, in, or near a targeted component of the pudendal nerve, and/or its branch(es), and/or its spinal root(s),
selecting an electrical signal having an amplitude,
applying the electrical signal at the selected amplitude to the electrode to selectively stimulate the targeted component, and
without substantially changing the selected amplitude, selecting between a first frequency or range of frequencies to achieve a first desired physiologic response and a second frequency or range of frequencies to achieve a second desired physiologic response different than the first physiologic response.
2. A method according to claim 1
wherein the targeted component comprises a urethral afferent of the pudendal nerve and/or afferent nerve fibers in the deep perineal nerve.
3. A method according to claim 1
wherein the physiological function comprises one of controlling urinary incontinence and controlling micturition.
4. A method for controlling a physiological function of the lower urinary tract comprising
placing at least one electrode on, in, or near afferent nerve fibers in the deep perineal nerve,
selecting an electrical signal having an amplitude,
applying the electrical signal at the selected amplitude to the electrode to selectively
stimulate the afferent nerve fibers in the deep perineal nerve and
without substantially changing the selected amplitude, selecting between a first frequency or range of frequencies to control urinary continence and a second frequency or range of frequencies different than the first frequency to control micturition.
