Abstract: A sensing device can be used for ambulatory urodynamics. The sensing device can include an elongated outer housing constructed of flexible material that can curve within a patient's bladder. At least a portion of the outer housing can be filled with a non-compressible fluid. A flexible printed circuit board can be disposed within the outer housing to curve with the outer housing. The printed circuit board can include a pressure sensor, comprising a diaphragm, to collect pressure data; a microcontroller running control software; and a wireless transmitter to transmit the pressure data. A battery can be disposed within the outer housing and coupled to the printed circuit board. The flexible material of the outer housing is configured to be displaced by a pressure within the patient's bladder, the displacement is transmitted through the non-compressible fluid to the pressure sensor that provides the pressure data based on the displacement.

Abstract: The present disclosure relates generally to using detected bladder events for the diagnosis of urinary incontinence or the treatment of lower urinary tract dysfunction. A system includes a sensing device comprising a pressure sensor to directly detect a pressure within a bladder. The sensing device is adapted to be located within the bladder. The system also includes a signal processing device to: receive a signal indicating the detected pressure within the bladder; detect a bladder event based the detected pressure within the signal; and characterize the bladder event as a bladder contraction event or a non-contraction event. The characterization of the bladder event can be used in the diagnosis of urinary incontinence or the treatment of lower urinary tract dysfunction.

Abstract: To perform urological diagnostics of a patient, detrusor pressure can be estimated using bladder pressure recordings from a single sensor. A signal comprising the bladder pressure data recorded by the sensor can be received. The bladder pressure data can include at least a detrusor pressure data component and a corrupting data component. An estimate of the corrupting data component can be extracted from the bladder pressure data. The detrusor pressure of the patient can be estimated based on the estimate of the corrupting data component and/or the estimate of the detrusor pressure data. An output indicative of the detrusor pressure of the patient can be provided based on the estimate of the detrusor pressure data component.

Abstract: A sensing device can be placed within the colon to study bowel function. The sensing device can include a flexible printed circuit board that includes at least one senor configured to record data related to bowel activity from a patient's colon; and a wireless transmitter configured to send the data from the patient's colon to an external device. The sensing device can also include at least one mucosal clip configured to fix the sensor board to a wall of the patient's colon for a measurement period. The flexible printed circuit board and/or the at least one mucosal clip are configured to be passed from the patient's colon after the measurement period through normal defecation.

Abstract: The present disclosure relates generally to estimating an interior diameter of a hollow organ. As such, one aspect of the present disclosure relates to a system that can include a light-based distance sensor and a device housing the light-based distance sensor located within the hollow organ. The light-based distance sensor can include an emitter and a detector. The emitter can transmit a conical beam of light to an inner surface of a hollow organ. The detector can receive a portion of the light back-reflected from the inner surface of the hollow organ. The device can determine a volume of the hollow organ based on a signal related to the back-reflected portion of the light, which can be based on a distance between the light-based distance sensor and the inner surface of the hollow organ.
