A reusable urinary catheter assembly includes a catheter shaft and a plurality of removable members associated with the catheter shaft. A different one of the removable members is configured to be removed from the catheter shaft between each consecutive use of the reusable urinary catheter assembly. By such a configuration, the number of times that the reusable urinary catheter may be reused is limited by the number of removable members.

Drug delivery devices having a drug-permeable component and methods of making and using the same are provided. Drug delivery devices include a housing having a first and second wall structures that are adjacent one another and together form a tube defining a drug reservoir lumen. The second wall structure, or both the first wall structure and the second wall structure, are permeable to water, and the first wall structure is impermeable to the drug while the second wall structure is permeable to the drug, such that the drug is releasable in vivo by diffusion through the second wall structure.

A balloon-manipulating device for a balloon catheter, methods of making, and methods of use. The balloon-manipulating device includes a tubular body, a longitudinal hole through a least a portion of the tubular body, one or more balloon-compressing pieces of a sidewall of the tubular body, and one or more balloon-letting through holes through the sidewall. The longitudinal hole may extend from an opened proximal end of the tubular body to at least a distal end portion of the tubular body, and is configured for inserting a balloon-catheter shaft therein. Each of the one or more balloon-compressing pieces is configured for compressing a different portion of an inflated balloon-catheter balloon when the balloon-manipulating device is disposed over the balloon. Each of the one or more balloon-letting through holes is configured for allowing therethrough a different portion of an inflated balloon-catheter balloon when the balloon-manipulating device is disposed over the balloon.

A purpose is to enable partial replacement of an indwelling urethral catheter. A unit for a balloon catheter according to the present invention includes a urethral catheter tube (13) provided with a first urethral catheterization passage (14), a branch tube (11) provided with a first passage (12) adapted to allow passage of a liquid used to inflate or deflate a balloon (54), and a connecting tube (30) configured to be connected at one end to the first urethral catheterization passage (14) or the first passage (12).

An internal drainage catheter for ascites drainage according to an embodiment has an improved structure so as to allow ascites in a peritoneal cavity to be discharged in urine via a bladder and ensure significant fixation force to a bladder wall based on which the peritoneal cavity and the bladder are separated from each other.

The present invention is a self-cleaning catheter designed to impede the development of biofilm within the catheter and provide a mechanism for removing biofilm within the catheter during use by a patient. The self-cleaning catheter includes an outer shell enclosing a urine lumen. The urine lumen has the ability to be opened and closed with a urine lumen closure device and is formed with a plurality of micro ports and a plurality of macro wash ports. At least one antimicrobial lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of micro ports. Similarly, at least one wash lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of macro wash ports. Antimicrobial solutions and wash solutions are introduced into the urine lumen by the antimicrobial lumen and wash lumen respectively, even during use.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

The presently described catheter is an improved multi-function hypospadias catheter adapted to be urethrally inserted and secured within a patient's bladder using an attached internal crescent shaped retention balloon. The inverted crescent configuration of the balloon reduces the contact surface area between the balloon and a patient's bladder wall to reduce bladder spasms. The catheter is removed from the patient (when needed) via deflation of the crescent shaped balloon, which deflates completely so as to not contact a patient's urethra during insertion and removal of the catheter. The catheter includes a double lumen with a one-way flow valve. One lumen provides a passageway to drain urine from a patient's bladder. The second lumen provides a passageway to inflate and deflate the crescent shaped retention balloon.

Laser fiber probe consists of a suction sheath with a suction window in the distal end of the sheath and a fiber conduit with fiber position regulator to limit and position the fiber laser window. The suction sheath and the fiber conduit are constructed that the suction window is used to catch up the surgery targets and also functions as the entrance of the surgery debris, where the fiber laser window is in contact with the sucked surgery targets. Hereby the surgery targets sucked by the suction window are made into debris through the laser energy emitted from the fiber laser window, while the surgery debris is evacuated all the way out of the patient through the suction, which improves the surgery efficiency and ultimately reduces the procedure time.

A tool is attachable to a bladder irrigation catheter. A body supports multiple fluid pathways between each of the catheter, a supply of irrigation fluid and a waste fluid collector. A syringe or other pressure and vacuum applicator accesses the pathways and powers irrigation flow. A supply port and intake port are connected to a supply pathway leading to the applicator. Similarly, a drain port and discharge port are connected to a drain pathway leading to the applicator. The supply pathway and drain pathway can be selectively blocked so that action of the applicator only drives supply or drain irrigation action. Check valves are located to provide proper fluid flow direction. Bypasses between the supply port and intake port and between the drain port and discharge port can be activated to bypass the supply pathway and drain pathway and allow for gravity flow bladder irrigation through the tool.
