Abstract: A system for incontinence prediction includes an electrical impedance tomography (EIT) device, a posture detector, and one or more processors communicatively coupled to the EIT device and the posture detector. The EIT device may include a plurality of electrodes configured to be worn at a lower abdomen of a user around the bladder. The one or more processors is configured to collect an EIT image generated by the EIT device, a posture generated by the posture detector, and a planning activity of the user. The one or more processors may further determine a bladder status based on the EIT image of the user, predict an incontinence risk based on the bladder status, the posture, and the planning activity of the user and determine a high-risk point indicating a high incontinence risk, and notify the user or a caregiver of the high incontinence risk at the high-risk point.

Abstract: Embodiments disclosed herein are directed to a self-learning bladder volume monitoring system. The system can include a bladder volume (BV) system configured to measure an electrical impedance of a bladder region of a patient and determine a volume of fluid disposed therein using an impedance to bladder volume model (“By model”). Further, the system can measure a total body water (“TBW”) for the patient and modify the BV model to account for variations in TBW within the tissues surrounding the bladder providing a more accurate bladder volume measurement. The system can include a “training unit” which can include one of a user input interface, an automatic urine output monitoring system, an ultrasound system, and an intrabladder pressure system configured to verify a volume of fluid within or voided from the bladder and train the BV model.

Abstract: Uroflowmeters and methods for processing data generated therefrom are disclosed. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber coupled to the handle, and a sensor associated with the flow chamber that detects a parameter of urine received in the flow chamber. The uroflowmeter may include both reusable and disposable components. As a uroflowmeter it can identify and record data corresponding to the rate of flow over the measured duration of a void of urine, but may also timestamp the voiding act and communicate the data to an external data collection center for additional analysis and incorporation into a comprehensive voiding report or voiding diary.

Abstract: A bladder fullness monitoring system 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.

Abstract: An implantable medical lead includes at least one stimulation electrode and at least one sensor configured to generate an electrical signal that varies as a function of a parameter associated with a voiding event of a patient. In some embodiments, the sensor may be at least one of a microphone that captures sounds associated with voiding events, a pressure sensor, a flow sensor, a strain gauge, a physiological parameter sensing electrode or a temperature sensor. The electrical signal generated by the sensor may used to detect an occurrence of a voiding event. Thus, the lead may be coupled wirelessly or via a wired connection to a device that processes the electrical signal from the sensor, generates voiding information based on the electrical signal, and in some cases, records the voiding information for later retrieval and analysis.
