A sanitary catheter drain device includes a catheter tube having an insertion end configured for insertion into a user to establish fluid communication with a bladder of the user. A drain valve coupled to an open end of the catheter tube. The drain valve has a closed position preventing fluid passage through the drain valve and an open position permitting fluid passage from the open end of the catheter tube through the drain valve. A cap is couplable to the drain valve such that the cap covers an outlet of the drain valve.

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 catheter, a guide wire, an opening position identification device, an opening position identification method, an internal object presence determination assistance device, a diagnostic assistance device, and a treatment assistance device that can easily identify the position of an opening of the catheter in a body are provided. A guide wire 20 is inserted into a catheter 30 having openings for introducing a fluid substance into the body, or for sucking the fluid substance in the body. One or more light sources 10 for identifying the positions of openings 32 of the catheter 30 are provided. The catheter 30 may be provided with one or more light sources 10 for identifying the positions of the openings 32 of the catheter 30.

Disclosed herein are systems, devices, and methods for the removal of objects from the body. The device may be a urethral catheter configured to aspirate kidney stones from the urinary tract through one or more aspiration ports at the distal face or along a lateral side of the catheter. The catheter may include one or more irrigation ports at the distal face or along the lateral side of the catheter for dislodging kidney stones. The device may be steerable. The spatial arrangement of the one or more irrigation ports with respect to the one or more aspiration ports may vary. The device may include an irrigation tube and/or a shield member configured to spatially confine the kidney stones adjacent the catheter. Various temporal patterns of aspiration and irrigation are disclosed for optimizing removal of kidney stones.

The present invention provides methods and systems for treating conditions and diseases of a patient's body cavities, including urinary incontinence, transitional cell carcinoma, and other conditions. In particular, the present invention describes a drug delivery system for controlled delivery of drugs to body cavities of a patient, and the use of this system for treatment of the body cavities of the patient, for example, intravesical treatment. Many medications prescribed to patients with urinary tract diseases act locally. In many cases, such medications are administered orally or intravenously and spread through the digestive tract and bloodstream throughout the body, thereby affecting other body systems such as the immune system, kidneys, or liver and causing problematic adverse reactions. For local treatment, the present invention applies the drug directly to the cavity in a minimally invasive procedure.

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, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen 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. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A ureteral catheter includes a drainage lumen including a proximal portion configured to be positioned in at least a portion of a patient's urethra and/or bladder and a distal portion configured to be positioned in a patient's kidney, renal pelvis, and/or in the ureter adjacent to the renal pelvis, the distal portion including a retention portion for maintaining positioning of the distal portion of the drainage lumen, the retention portion including two or more openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen, wherein a number of the openings nearer to a distal end of the retention portion is greater than a number of the opening(s) nearer to a proximal end of the retention portion.

A retainer system includes a catheter tube, a bifurcation, a drainage extension leg and an inflation extension leg. The system can also include an anchor pad and a retainer rotatably coupled to a top surface of the anchor pad. The retainer can include a base and a cap hingedly coupled to the base. Additionally, the retainer can feature one or more extension leg sleeves with a lumen, extending from the first side of the retainer, and a catheter tube sleeve with a lumen, extending from the second side of the retainer. The sleeve can define a serpentine shape to impart a predetermined amount of slack on the catheter and mitigate dislodgement of the catheter distal tip when the retainer system moves relative thereto. Further, the retainer system can mitigate kinking or collapse of the catheter by providing strain relief between the catheter and the retainer system.
