In some embodiments, a catheter system may include a catheter adapter having a distal end, a proximal end, and a lumen extending there between. In some embodiments, the catheter system may also include a catheter extending distally from the distal end of the catheter adapter, an extension tube, and a connector coupled to a proximal end of the extension tube. In some embodiments, a distal end of the extension tube may be coupled to the proximal end of the catheter adapter. In some embodiments, the connector, the extension tube, the lumen, and the catheter may form a straight pathway for delivery of an instrument to the catheter system. In some embodiments, an extension set for a catheter assembly may include the extension tube, the connector coupled to the proximal end of the extension tube, and another connector coupled to the distal end of the extension tube.

A method to manage flushing of a catheter assembly may include providing a clamp for a fluid tube configured to be coupled to the catheter assembly. The clamp may include a sensor configured to detect the clamp is closed. The method may include starting a timer in response to the sensor detecting the clamp is closed. The method may include providing an alert in response to the timer reaching a predetermined duration of time. The alert may indicate to a clinician that the catheter assembly should be opened and flushed, which may prevent occlusion of the catheter assembly.

The disclosure provides a device and method for managing urinary incontinence. The device includes a platform, a balloon, and a valve. The platform and balloon can include a silicone material, a thermoplastic material, and an adhesive and/or a cement for sealing the urethra. The thermoplastic and silicone materials can soften at the body temperature so that their shape can be adapted to fit the three-dimensional contour of surfaces of the urethra. The balloon seals the internal orifice of the urethra, and the platform can block the leakage associated with the balloon. The valve permits selective urine voiding. The method includes inserting the device into the urethra and the bladder. The method can also include inflating the balloon. The method can further include pulling the balloon so that the balloon is in sealing contact with the neck of the bladder and moving the platform to a suitable position for sealing the urethra.

Ureteral or bladder catheters are provided, including (a) a proximal portion; and (b) a distal portion, the distal portion including a retention portion that includes one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter. Systems, kits and methods for inducing negative pressure to increase renal function also are provided.

Urinary catheter-insertion kits can include a working tray, a storage tray, a urinary catheter, and a drainage system including drainage tubing and a drainage receptacle. The working tray can be configured to nest with the storage tray by suspending the working tray from the storage tray. At least the working tray includes a number of preformed sections configured to hold a number of components of the urinary catheter-insertion kit. At least one section of the preformed sections of the working tray includes a catheter section configured to hold the urinary catheter. The storage tray can be configured to hold the drainage system. Methods of urinary catheterization include use of the urinary catheter-insertion kits.

The invention provides a packaged intermittent catheter, the intermittent catheter comprising a hollow polymeric tubular body comprising a base polymer and an amphiphilic lubricious additive, housed in a packaging container; and further comprising an aqueous solution in the packaging container; wherein the aqueous solution comprises at least one compound selected from the group comprising: a surfactant and/or poly (alkylene oxide) compound with a total concentration of at least 0.005 mmol/L; and a salt in a concentration of at least 5% w/v.

Embodiments disclosed herein are directed to a drainage system for draining a fluid from a patient where the system includes a drainage tube that provides fluid communication between a catheter and a collection container. The drainage tube includes a port and a balloon attached to an interior of the drainage tube, where the balloon is configured to receive air from a needle that has pierced the port and occlude a lumen of the drainage tube. When in an inflated state, the balloon occludes the lumen of the drainage tube thereby breaking the fluid communication between the catheter and the collection container and preventing the output airflow device from drawing airflow out of the catheter. The balloon may be attached to the interior of the drainage tube by surrounding an interior side of the port.

The invention provides an intermittent catheter comprising a hollow polymeric tubular body comprising a base polymer and further comprising an amphiphilic additive at and/or on an outer surface of the body, wherein one or both of the base polymer and the additive are independently cross-linked and/or the base polymer and additive are cross-linked with each other.

The invention provides an intermittent catheter comprising a hollow polymeric tubular body comprising a base polymer and a lubricious additive, wherein the lubricious additive comprises an amphiphilic molecule having a hydrophilic-lipophilic balance below 8.

A urinary catheter assembly includes a first outer package having a first material, a second inner package contained inside of the first outer package, and an intermediate cavity defined as an area inside the first outer package and outside the second inner package. The first material has a first water vapour transmission rate (WVTR) measured according to ASTM F1249 at 90% relative humidity (RH) and 38° C. between 1 g/(m2.Math.24 h) and 6 g/(m2.Math.24 h). The second inner package has a second material having a second WVTR measured according to test method A at 65% RH and 30° C. below 3 g/(m2.Math.24 h). The second inner package contains a swelling medium and an intermittent urinary catheter with a hydrophilic coating.
