1. A medical system comprising:
- a therapy delivery module configured to generate and deliver electrical stimulation therapy to a patient, the electrical stimulation therapy configured to reduce a likelihood of at least one of a urinary voiding event or a fecal voiding event;
at least one of a sensor or a user input mechanism, wherein the sensor is configured to sense a patient ammeter indicative of an increased probability of at least one of the urinary voiding event or fecal voiding event, and wherein the user input mechanism is configured to receive user input from a user indicative of at least one of an imminent involuntary voiding event of the patient or an increased possibility of an occurrence of an involuntary voiding event of the patient; and
processing circuitry programmed to;
detect, based on input received from at least one of the sensor or the user input mechanism, a trigger event that triggers the processing circuitry to control delivery of the electrical stimulation therapy,responsive to detecting the trigger event, determine a number of trigger events that have been detected within a predetermined interval of time,determine that the number of trigger events does not exceed a threshold value, andresponsive to determining that the number of trigger events does not exceed the threshold value, control the therapy delivery module to deliver the electrical stimulation therapy to the patient according to a stimulation therapy program selected to reduce the likelihood of at least one of the urinary voiding event or the fecal voiding event.

Abstract
Techniques for managing urinary or fecal incontinence include delivering a first type of therapy to generate a first physiological response and, upon detecting a trigger event, delivering a second type of therapy to generate a second physiological response. The first type of therapy can be delivered on a substantially regular basis, while the second type of therapy is delivered as needed to provide an additional boost of therapy. The trigger event for activating the delivery of the second type of therapy may include input from a sensor that indicates a bladder condition, patient activity level or patient posture, or patient input. In some examples, the therapy is stimulation therapy.
