A urinary catheter can be retained inside the body for extended periods. A catheter mating device can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter includes: (1) a tube having a lumen and an outer surface, (2) a retainer that may have an attachment portion attached to the tube and a flap or handle-shaped structure attached to the attachment portion, wherein the retainer has a first, contracted position and a second, extended position, and (3) an bladder retention structure at the catheter's distal end, wherein the bladder retention portion may comprise a flap or a handle-shaped portion and that has a first, compressed position and a second, extended position. The retainer and/or bladder retention structure each are configured to retain the catheter in the proper position inside of a user's body.

The test lab set-up includes a test flow bench for mounting one or more test devices, an adjustable nozzle for simulating urine flow, and a sensor for collecting data associated with the simulated urine flowing through the test device(s). A computing device for measuring and/or calculating various parameters associated with the simulated urine flow may also be included. The test device may have a shape corresponding to a handheld uroflowmeter subject to testing. The angle of the adjustable nozzle may be adjusted to test for various angles of urine flow. Similarly, the angle, pitch, and roll of the test device may be adjusted to test for various angles at which a uroflowmeter is held. As fluid flows through the test device, the sensor collects information such as, for example, flow rate, duration, volume, and the like. The sensor transmits the data collected to a computing device for additional processing.

The present disclosure provides a urodynamic measurement apparatus that includes a urethral catheter that may be inserted into a patient's urinary bladder; a first sensor that is connected with the urethral catheter to measure an internal pressure of the urinary bladder; an abdominal catheter that may be inserted into a patient's rectum; a second sensor that is connected to the abdominal catheter to measure an abdominal pressure; and a first position adjusting part for adjusting heights of the first sensor and the second sensor according to the position of the patient's pubis.

Described is a catheter for being retained inside the body for extended periods, and a catheter mating device that can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter mating device has a stem with an apparatus at its distal end. The apparatus is moveable between a first position and a second position. When in its first position, the distal end is configured to fit in the proximal end of the catheter. When in its second position, the distal end engages the proximal end of the catheter and connects the catheter mating device to the catheter.

A bladder pressure measurement device comprises a conduit for receiving a flow of urine, a valve actuatable between a first open configuration and a second restricted configuration, a pressure sensor, upstream of the valve and arranged to measure the pressure of the flow of urine through the conduit, and a data recorder and/or a data transmitter. The pressure sensor obtains a first measurement when the valve is in the first open configuration and a second measurement when the valve is in the second restricted configuration. The data recorder and/or transmitter records or transmits data representative of the first and second measurements.

In some embodiments, an external bladder management system that is configured to reside within a urine collection receptacle (e.g., a toilet) includes a body that houses a fluid testing chamber. The fluid testing chamber is fluidically coupled to a fluid inlet and a fluid outlet. The system further includes a fluid capturing funnel fluidically coupled to and extending from the body and configured to couple the body to the urine collection receptacle. The system further includes an optical sensor disposed within the body and including (1) an emitter configured to convey light across the fluid testing chamber, and (2) an optical detector capable of measuring an intensity of the light as the light exits the fluid testing chamber. The fluid inlet, fluid testing chamber, and fluid outlet are collectively configured to encourage a laminar flow profile of the fluid as it flows through the fluid testing chamber.

The present disclosure provides a urodynamic measurement apparatus that includes a urethral catheter that may be inserted inside a patient's bladder, a first sensor that may be spaced apart from the patient, and connected to the urethral catheter to measure an inner pressure of the bladder, a rectal catheter that may be inserted inside the patient's rectum, a second sensor that may be spaced apart from the patient, but adjacent to the first sensor, and connected to the rectal catheter to measure an abdominal pressure, and a first position adjuster that adjusts the height of the first sensor and the second sensor according to the patient's posture.

In some examples, a medical device includes an elongated body defining an inner lumen. The medical device further includes an anchoring member and a first sensor at a proximal portion of the elongated body, and a second sensor at a distal portion of the elongated body or distal to a distal end of the elongated body. The second sensor is configured to sense a substance of interest and the elongated body comprises a material that is a substantially non-permeable to the substance of interest.

A catheter for measuring pressure in the urinary tract of a patient includes a catheter body having a proximal and distal end. A plurality of lumens is formed in the catheter body, and an adaptor is coupled to the proximal end of the catheter body. The adaptor includes a port for each lumen. A first pressure sensor, typically including a balloon, is fluidically coupled to a first lumen and is configured and positioned to measure pressure in a urethra of the patient. A second pressure sensor, also typically including a balloon, is fluidically coupled to a second lumen and is configured and positioned on the catheter body to measure pressure in a bladder of the patient. An expandable retention member, which may be coupled to a third lumen, is positioned on the catheter body between the first and second expandable pressure sensors so that the catheter body may be retained at a selected location in the urinary tract to properly position the fluid pressure sensors in the bladder and urethra, respectively.

The invention relates to a detection system of an endo-urethral device for an artificial urinary sphincter implantable in the body of a patient, said sphincter comprising an occlusive cuff (2) adapted to compress the urethra, the bladder neck or the prostate of said patient, an activation device (5) of said cuff (2) and a control unit (6) adapted to control the activation device. Said system comprises at least one compression sensor (13) of the urethra and a posture sensor (9), and a processing unit (30) configured to determine: (i) if the compression parameter of the urethra exceeds a predetermined threshold during a predetermined period, (ii) if the patient is in a recumbent position. If the conditions (i) and (ii) are fulfilled, the processing unit sends to the activation device (5) an immediate reduction order of the compression exerted by the cuff (2).
