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.

A method of fracturing a previously-implanted prosthetic surgical heart valve may include advancing a non-compliant balloon of a balloon catheter through a patient's vasculature until the balloon is positioned at least partially within the previously-implanted prosthetic surgical heart valve. Inflation media may be advanced through an inflation lumen and into the balloon to inflate the balloon. A pressure within the inflation lumen may be measured during advancing the inflation media. A volume of inflation media advanced through the inflation lumen and into the balloon may be measured. A relationship between the measured pressure and the measured volume of inflation may be monitored, as the inflation media is advanced into the balloon, to identify distinct phases of balloon inflation.

Sensing and infusion devices are described. In one embodiment, a sensing and infusion device may include an implantable segment having a sensor. The sensing and infusion device may also include a catheter, and a sensor channel may be formed in the catheter. The sensor channel may be configured to retain at least a portion of the implantable segment.

This application relates to a pressure sensor array for urodynamic testing capable of simultaneously measuring bladder pressure, prostate pressure, and urethral pressure, and to a test apparatus including the pressure sensor array. In one aspect, the pressure sensor array for urodynamic testing is installed in a catheter and includes a base substrate having flexibility. The pressure sensor array may also include a bladder pressure sensor formed on a portion of the base substrate to be positioned in bladder and measuring bladder pressure. The pressure sensor array may further include a prostate pressure sensor formed on a portion of the base substrate to be positioned in prostate and measuring prostate pressure. The pressure sensor array may further include a urethral pressure sensor formed on a portion of the base substrate to be positioned in urethra and measuring urethral pressure.

An apparatus and methods for use are provided, where the apparatus includes: (a) a first catheter having a proximal end and a distal end, and wherein a distal portion of the first catheter includes a first one or more outlets, (b) a first tubular housing having a proximal end and a distal end, wherein the first tubular housing is coupled to the first catheter proximal to the at least one first outlet, (c) one or more pressure sensors coupled to the distal end of the first tubular housing, and (d) a second catheter having a proximal end and a distal end, wherein a distal portion of the second catheter includes a second one or more outlets, and wherein the distal end of the second catheter is configured to be positioned substantially within one of (i) the first catheter or (ii) a second tubular housing coupled to one or more of the first catheter and the first tubular housing, when the second catheter is in a first position.

Provided herein is an angioplasty balloon inflation device. The angioplasty balloon inflation device includes a processor; a pressure sensor coupled to the processor; a motor coupled to the processor; and an inflation element including a first end coupled to the motor and a second end configured for coupling to an angioplasty balloon. The motor is configured to adjust the pressure in the angioplasty balloon through the inflation element, the pressure sensor is configured to monitor pressure in the angioplasty balloon, and the processor is configured to control the motor based upon the pressure monitored by the pressure sensor. Also provided herein is a method of performing percutaneous transluminal balloon angioplasty (PTA) using the device.

Medical testing devices and methods of diagnosing are disclosed. One device may include, a catheter; an inflatable balloon located in a distal portion of the catheter, wherein the inflatable balloon is at least partially insertable into a body cavity; one or more pressure sensors located inside the inflatable balloon; an inflating unit in fluid connection with the inflatable balloon; and a control unit attached to the catheter and configured to receive pressure measurements from the one or more pressure sensors; and to control the inflating unit to control the pressure inside the inflatable balloon based on the received measurements.

This application relates to a system, device, and method for detecting and draining urine. The catheter uses at least two teardrop-shaped retention balloons and a balloon-blocking mechanism to allow efficient and complete urine drainage away from the user after urination.

In another embodiment, urine is automatically detected by a sensor and drawn away from the user by a pump to a storage location.

Proposed is a drug-eluting expandable urethral balloon catheter. The drug-eluting expandable urethral balloon catheter includes a tube part inserted into the urethra, a separation prevention part including a first balloon that expands in the bladder according to the inflow of fluid to prevent separation the of tube part and maintain airtightness of the bladder, a drug injection part having a plurality of pores formed so that a drug is injected into the stricture site of the urethra, a urethra expansion part including a second balloon which is positioned on a front end of the drug injection part and inflates or contracts according to the inflow and outflow of fluid, and a branched connection part branched from one side of the tube part to be connected thereto so as to enable fluid to flow in and out of the tube part.

The present disclosure discusses a urinary catheter attachment that is equipped with a sensor and microcontroller that monitors bladder parameters, such as pressure or volume, and determines when the bladder is full and should be voided. In various embodiment, the disclosed system allows individuals who cannot know, feel, or remember when their bladder should be voided to use catheter accessories such as catheter valves. According to various embodiments, the system computes bladder fullness through an algorithm and triggers the alert system when a bladder fullness threshold is passed. In various embodiments, the alert system includes, but is not limited to, notifications via smartphone or smart devices, wearable technology, and patient management systems. The alert system may be substituted with an electronically actuated catheter valve.
