A bladder fullness monitoring systems includes a controller and an active optical sensor that is affixed to a patient's bladder. The sensor emits light onto the bladder and further detects light reflected from the bladder, in order to generate an output signal that indicates an amount of emitted light was reflected back to the detector. The controller is coupled to the optical sensor to receive and interpret the output signals, e.g., to determine when the bladder is full. The controller may be operatively coupled to a urinary control apparatus which uses the output signals to trigger urination in patients who have lost the ability to voluntarily urinate. Embodiments are particularly useful for monitoring bladder fullness in patients who have lost bladder sensation and/or the ability to voluntary urinate and rely on a urinary control apparatus in order to urinate.

The disclosure describes a system comprising: a memory; and one or more processors in communication with the memory. The one or more processors are configured to: receive, from a set of sensors, biometric data indicative of a muscle contraction of a patient over a period of time; and determine, based on the biometric data, a muscle contraction vector indicating a direction of the muscle contraction over the period of time. Additionally, the one or more processors are configured to determine, based on the biometric data, a likelihood that the muscle contraction comprises a true labor uterine contraction; and output, for display by a user device, the muscle contraction vector indicating the direction of the muscle contraction and the likelihood that the muscle contraction comprises a true labor uterine contraction.

A system to determine status of a pelvic condition in a subject characterised by abnormal contractility activity of a target pelvic structure is described. The system comprises a sensing module to measure electrical activity of the subjects pelvis at a plurality of time points during the subjects hormonal cycle, a signal processing module configured to receive electrical activity measurements from the sensing module and isolate from the electrical activity measurements electrical contractility parameter measurements representative of the target pelvic structure, and a processor module operably connected to the signal processing module. The processor is configured to receive as an input the electrical contractility parameter measurements representative of the target pelvic structure, generate a data profile of the subject comprising the electrical contractility parameter measurements representative of the target pelvic structure, compare the data profile with a database of reference data profiles comprising reference data profiles of subjects with different pelvic condition status, output the status of the pelvic condition in the subject based on the comparison. In any embodiment, the signal processing module is configured to isolate from the electrical activity measurements slow wave electrical contractility parameter measurements representative of the target pelvic structure. Systems and methods for treating pelvic conditions comprising stimulation of a pelvic structure to normalise pelvic structure contractility are also described.

This disclosure describes methods, systems, and devices configured to determine a timing of a future bladder related event of a patient. For example, a system includes processing circuitry configured to identify a timing of a plurality of bladder related events of a patient, determine, based on the timing of the plurality of bladder related events of the patient, a probability to experience a bladder related event function for the patient, the probability to experience a bladder related event function indicating a probability that the patient will experience a bladder related event at an elapsed time after a previous bladder related event, predict, based on the probability to experience a bladder related event function, a timing of a future bladder related event, and control delivery of a therapy to the patient based on the predicted timing of the future bladder related event.

A disposable medical device assembly for measuring a physiological parameter in a urinary or gastrointestinal tract of a mammal being is disclosed, comprising a probe, such as a catheter, for insertion into a bodily opening of the mammal being. The probe comprises at least one sensor, such as a pressure sensor. The medical device further comprises an energy source, in the form of a biofuel cell, connected to the at least one sensor.

Provided are devices and methods for preventing an episode of incontinence in an individual in need thereof. The devices comprise a sensor and a stimulator electrode that can be implanted into the body of the individual. Once the device is implanted in the individual, the sensor of the device senses a parameter that is associated with a response from the individual that is intended to prevent an episode of incontinence. Then, the device provides an electrical stimulation using the electrode that, together with the response, helps to prevent the episode of incontinence.

A urodynamic investigation apparatus for receipt of urine from a bladder is provided. The apparatus is characterized by a tubular element, first and second fittings, and a sleeve element, for select passage of urine there through, within the tubular element. The tubular element is characterized by opposing first and second end portions, and a port. The fittings are adapted to be received by the opposing end portions of the tubular element so as to delimit an apparatus chamber. The sleeve element, suspended between the fittings within the chamber, has collapsed and open configurations. The collapsed configuration is indicative of a no urine flow condition, and the open configuration indicative of a urine flow condition, with the sleeve element urine flow condition being a function of pressure applied to the chamber via the port of the tubular element.
