A catheter insertable into a urethra for installation in a user's bladder and urethra, the catheter comprising: a urine conduit comprising a first urine inlet and a urine outlet; and an inlet protector extending outwardly from the urine conduit from a position between the first urine inlet and the urine outlet, where the inlet protector functions to protect the urine inlet by separating it from contact with the bladder wall and thus keeping it out of contact with tissue.

A urinary catheter with deflectable tip, comprising a hollow catheter body configured to be inserted within the urethra of a patient, the catheter body having an elongate portion, a tip portion near a distal end of the elongate portion and an engagement portion spaced from the distal end where a user can grasp the catheter, the tip portion being deflectable for the purpose of steering the catheter within the urethra to allow the catheter to follow a natural curvature of the urethra, the tip portion being movable from a generally straight condition to a deflected condition wherein deflection of the tip portion occurs while the elongate portion remains generally straight.

Systems and methods for treatment of small patent urachal duct remnant (SPUDR) are described. The systems include kits for treatment of SPUDR, the kits including a microwire, a microcatheter, a support catheter and a sheath within common packaging. The kit may include a sclerosing agent or glue as well as instructions for treatment of SPUDR. Methods for treatment may include steps of navigating an assembly of a microwire and microcatheter to the SPUDR and injecting a sclerosing agent or glue into an orifice of the SPUDR.

A kit comprising: a urinary catheter comprising a first and a second longitudinal lumens; an ultrasonic transducer disposed about said catheter; a balloon mounted on said catheter, and enclosing said transducer; and a reservoir containing an acoustic coupling medium, wherein: said catheter further comprises a first opening in said first longitudinal lumen, said first opening disposed inside said balloon and configured to inflate said balloon with at least some of said acoustic coupling medium, said catheter further comprises a second opening in said second longitudinal lumen, said second opening disposed outside said balloon and configured to deliver a therapeutic fluid into the urinary bladder, around said balloon, and activation of said transducer in said urinary bladder causes cavitation bubbles to form in said therapeutic fluid adjacent an internal surface of the urinary bladder, and little or no cavitation bubbles are formed in said acoustic coupling medium in said balloon.

A ureteral catheter is provided, including: a drainage lumen including a proximal portion configured to be positioned in at least a portion of a patient's urethra and a distal portion configured to be positioned in a patient's ureter and/or kidney, the distal portion including a coiled retention portion, wherein the retention portion includes at least a first coil having a first diameter and a second coil having a second diameter, the first diameter being less than the second diameter.

An improved catheter has an elongated shaft with at least one drainage lumen and one or more toroidal balloons coaxially mounted thereto. Each balloon provides an internal balloon surface that is either continuous, forming an inner channel and a first toroidal space, or non-continuous, the surface and shaft bounding a second toroidal space at attachment points. Lubricant applied to the shaft and/or the toroidal spaces lowers friction where opposed portions of the internal surface meet or contact the shaft, enabling rolling or inversion of the balloon while its external surface remains stationary against the lumen wall. Optional features include dedicated inflation ports, inflation/deflation valves with pressure-relief elements, rupture seams actuated by a cutting ring, retention balloons, and spaced toroidal balloons positioned to shield the prostate and distal urethra.

Compositions and methods for the application of non-toxic bioparticle (e.g., extracellular vesicle (EV)) absorbing materials (e.g., non-toxic exosome reducing materials) for prophylactic, therapeutic, validation and/or experimental purposes are provided.

A system for removing fluid from a urinary tract includes at least one sensor configured to detect signal(s) representative of pulmonary artery pressure and communicate signal(s) representative of the pulmonary artery pressure and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the pulmonary artery pressure is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the pulmonary artery pressure signal(s) received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter to remove fluid from a urinary tract when the pulmonary artery pressure is above the predetermined value and to cease applying negative pressure when the pulmonary artery pressure is at or below the predetermined value.

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.
