Ureteral catheters and assemblies are 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 including 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; or wherein the retention portion extends radially outwardly from a portion of the distal end of the drainage lumen portion, the retention portion including a proximal end having a first diameter, a distal end having a second diameter, and a wall and/or surface extending therebetween, the retention portion having a second diameter is greater than the first diameter when deployed; or wherein the retention portion includes a plurality of drainage tubes.

A catheter has an entrance opening defined by the first end of a catheter body and non-circular inner surface in cross section. The entrance opening intersects a longitudinal axis extending longitudinally through the center of a lumen adapted to drain urine from a bladder. The non-circular inner surface can have dimples, channels, or grooves, all of which decrease frictional fluid forces against the inner surface as the urine drains. The catheter is free of any eyelets formed in the side wall of the catheter body. The catheter further includes a plurality of distinct longitudinally extending convex outer surfaces and may have an enlarged head.

A percutaneous urinary catheter configured to be deployed in a urinary tract, including: (a) a proximal portion; and (b) a distal portion including a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion including one or more drainage holes leading to one or more lumen(s) within the proximal portion, wherein the retention portion, when deployed, defines a three-dimensional shape sized and positioned to maintain patency of fluid flow between the kidney and/or renal pelvis and a proximal end of the catheter by inhibiting mucosal tissue from appreciably occluding the one or more drainage holes when negative pressure is applied through the catheter.

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 body fluid movement system includes a body fluid movement apparatus with a lumen, a proximal end, a distal end and a balloon coupled to the proximal end. The balloon is configured to be positioned in an interior of a bladder. The proximal end is configured to provide flow of body fluid from the bladder through the body fluid movement apparatus and collects body fluid from the bladder through the lumen. The drainage bag has an inlet port for receiving body fluid and an outlet port for draining body fluid urine from the drainage bag. The body fluid movement tube includes the proximal end, with a plurality of body fluid draining holes that receive body fluid urine from the bladder and allow it to be transported to and though the body fluid movement tube. One or more sensors are included in the body fluid movement apparatus and positioned to be in contact with patient's body fluid. A patient remote monitoring system is coupled to the one or more sensors to receive sensor data.

A catheter comprising: a shaft (1) having a proximal end (2) and a distal end (3), the distal end terminating in a tip (4); a drainage opening (7) located at the distal end of the shaft, the drainage opening communicating with a drainage lumen (8) of the shaft; a balloon located at the distal end of the shaft, the balloon comprising a first region secured to the shaft, a second region secured to the shaft and an elastic-walled conduit extending between the first region and the second region, the elastic conduit extending over the tip.

A catheterization package including a catheterization tray and contents for a catheterization procedure. The catheterization tray can include a structural configuration for maintaining a sterile field about a patient throughout the catheterization procedure, the sterile field including at least a portion of the tray. The structural configuration of the tray can provide a sterile side of the tray designated for a first person performing sterile steps of the catheterization procedure in the sterile field. The structural configuration of the tray can also provide a non-sterile side of the tray designated for either the first person or a second person performing non-sterile steps of the catheterization procedure outside the sterile field. The contents for the catheterization procedure can include a perineal care kit, two or more pairs of gloves, and a drainage system including a catheter.

Apparatus and methods for treatment of bleeding and/or microbial infection of the genitourinary tract including a catheter and an insertable and removable medicament-delivery sheath for introducing a hemostatic and/or anti-microbial substance or the like. Some embodiments further include a light-delivery sheath and/or light-delivery-and-imaging sheath having a light-propagation channel, and a source of anti-microbial and/or imaging light in one or more wavelength bands, for example UVC light and/or light in the visible violet, blue or green wavelength ranges. Some embodiments include a display for captured images, and/or a motorized sheath-movement device configured to move one or more light-output ports. Some embodiments further include a light-propagation channel built into the catheter itself (such as one or more optical fibers) for the administration of anti-microbial ultraviolet light (and/or other wavelengths of light) light along the catheter and/or at the distal end of the catheter to treat and/or prevent microbial (bacterial and/or fungal) infections.

An implantable medical device is provided for controlled drug delivery within the bladder, or other body vesicle. The device may include at least one drug reservoir component comprising a drug; and a vesicle retention frame which comprises an elastic wire having a first end, an opposing second end, and an intermediate region therebetween, wherein the drug reservoir component is attached to the intermediate region of the vesicle retention frame. The retention frame prevents accidental voiding of the device from the bladder, and it preferably has a spring constant selected for the device to effectively stay in the bladder during urination while minimizing the irritation of the bladder.
