Negative pressure therapy systems are provided for increasing urine production, the negative pressure therapy system including: (a) a pump assembly, the pump assembly including: (i) a pump configured to provide negative pressure to a kidney, and (ii) a controller configured to regulate the negative pressure provided by the pump within a pressure range that facilitates increased urine production from the kidney.

The present invention relates to a catheter system for urine extraction comprising: (a) a genital adapter configured to fit a genitalia; (b) an adapter base connected to said genital adapter; (c) an operational tube connected to said adapter base; (d) a base unit, connected to said operational tube, and comprising an electric pump and a controller; (e) at least one control interface for commanding said controller; (f) a catheter tube having a first end for insertion into said base unit and having a second end for insertion into said operational tube, said adapter base, and said genital adapter; and (g) wherein said second end of said catheter tube is configured to extend through said genital adapter to the urinal bladder and to extract urine from said urinal bladder by said electric pump.

Described herein are various embodiments of flexible catheters comprising one or more flexibility regions. In one embodiment, a catheter comprises an elongate body having a proximal segment and a distal segment; a first lumen defined by the elongate body and configured for drainage of a liquid from a bodily region; and a plurality of flexibility regions on or in the distal segment of the elongate body. The plurality of flexibility regions, collectively, is configured to passively bend anteriorly. Further, at least one of the plurality of flexibility regions has a cut depth percentage of about 50% to about 75% of a wall thickness of the elongate body. The features and arrangement of the flexibility regions described herein result in the catheter requiring reduced force during insertion into a bodily lumen.

A flushable catheter having an outer wall defining an inner conduit and an inner core member positioned within the inner conduit. The inner core being made from flushable materials, which are preferably degradable water soluble materials such that the inner core degrades as urine or water pass through the inner conduit defined by the outer wall.

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.

A catheter guide tube device (10) to assist in the insertion of a catheter (11) through a genital urethary system to a desired location within a patient's body. The catheter guide tube device (10) includes a catheter (11), a catheter guide tube (14) being attached to the catheter, and a catheter injection system (26) to regulate and control a flow of liquid through the catheter.

Disclosed herein are intermittent catheters and methods thereof. In an example of an intermittent catheter, the intermittent catheter can include a catheter tube, a lubricant disposed over a surface of at least a distal portion of the catheter tube, and a funnel coupled to a proximal portion of the catheter tube. The catheter tube can be of a polymeric material. The lubricant can have a solid state below 68? F. and a liquid state above 68? F. such that the lubricant transitions into the liquid state upon insertion into a urethra of a patient or user. The funnel can include a funnel opening in a proximal end of the funnel for voiding urine. In an example of a method of an intermittent catheter, the method can include a method of making or using the intermittent catheter.

Disclosed herein is a urinary catheter assembly including a package container that is transitionable between an expanded open configuration and collapsed closed configuration having the catheter and a bag enclosed therein. The container is transitioned from the closed configuration to the open configuration in one motion by the user pulling tabs in opposite directions. The container may be sterilized along with the catheter, may define a sterile barrier and may include a tamper evident mechanism. The container is securable in the closed configuration enclosing the catheter therein before and after use of the catheter. The catheter assembly may also include a urine collection bag enclosed within the container.

A medical device for use during radiation therapy may include a longitudinal body configured to be positioned within a urethra. The longitudinal body may include a lumen, a distal end, and a proximal end. A first balloon may be coupled to a distal portion of the longitudinal body and fluidly connected to a first port at the proximal end of the longitudinal body. A second balloon may be positioned between the first balloon and the proximal end of the longitudinal body and fluidly connected to a second port at the proximal end of the longitudinal body.
