  • Patent number: 11253314
    Abstract: The disclosure describes devices, systems, and techniques for identifying and treating bladder dysfunction. In one example, a method includes identifying one or more focal points at respective locations of bladder tissue of a bladder of a patient, the one or more focal points initiating coordinated contractions of a detrusor muscle. The method may also, or alternatively, include ablating, for each of the one or more focal points, a respective portion of the bladder tissue at the respective location of the focal point. Ablation of these targeted portions of the bladder tissue may reduce the coordinated contractions of the detrusor muscle and alleviate overactive bladder symptoms.

  • Patent number: 11045650
    Abstract: In general, techniques, methods, systems, and devices for delivering high frequency neurostimulation to control one or more pelvic disorders are described. In one example, a method includes identifying, by a medical device configured to be at least partially implanted in a patient, an indication to inhibit bladder activity. The medical device generates, in response to identifying the indication, electrical stimulation therapy comprising first electrical stimulation pulses comprising a first frequency greater than or equal to about 500 Hertz and less than or equal to about 5,000 Hertz. Further, the medical device delivers the electrical stimulation therapy to a target nerve selected from a group consisting of: a sacral nerve, a pelvic nerve, a tibial nerve, and a pudendal nerve of the patient.

  • Patent number: 9186509
    Abstract: Electrical stimulation therapy may be delivered to a patient to selectively and independently address different conditions of a pelvic floor disorder of the patient. The conditions of a pelvic floor disorder may include, for example, a lower urinary tract dysfunction (e.g., urinary or fecal incontinence) and sexual dysfunction (e.g., an impaired sexual reflex response to a sexual stimulus). In some examples, a system is configured to selectively deliver a first electrical stimulation therapy that is configured to elicit an inhibitory physiological response from the patient related to voiding, a second electrical stimulation therapy that is configured to improve a sexual reflex response of the patient to a sexual stimulus, and a third electrical stimulation therapy that is configured to both elicit the inhibitory physiological response from the patient related to voiding and increase a sexual response of the patient to a sexual stimulus.
