A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

Described is a catheter for being retained inside the body for extended periods, and a catheter mating device that can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter mating device has a stem with an apparatus at its distal end. The apparatus is moveable between a first position and a second position. When in its first position, the distal end is configured to fit in the proximal end of the catheter. When in its second position, the distal end engages the proximal end of the catheter and connects the catheter mating device to the catheter.

An insertion aid for catheter manipulation is disclosed. The insertion aid can be used for urinary catheters, such as hydrophilic urinary catheters for intermittent use. The insertion aid includes first and second plate-like arms arranged overlying each other and with a separation distance there between. The insertion aid also includes a resilient hinge connecting adjacent marginal edges of the plate-like arms together. At least one of the plate-like arms includes a groove on its clamping inner surface for holding a catheter shaft. The groove extends at least partly in the same direction as, and essentially parallel to, the resilient hinge, and is arranged at a distance both from the resilient hinge and from the marginal edge of the plate-like arm. Corresponding catheter set and catheter assembly are also disclosed.

Systems and methods for perfusing a treatment solution into the blood stream of particular organs while isolating those organs from the systemic vasculature as a whole. By deploying both collection and supply catheters, some having balloons on their distal ends, to particular locations within the body, various organs can be isolated so that the treatment solution can be delivered directly thereto. By isolating the organs, any side effects that may occur from a systemic introduction of the treatment solution are avoided. The method may be used to isolate not just organs, but specific tumors within certain organs for oncology treatment.

The invention provides a catheter (1) which is movable between an un-expanded and an expanded configuration by use of an advancing mechanism (20). The advancing mechanism facilitates safe and non-contaminated use of the catheter.

In one embodiment, a device measures the length of the urethra. The device includes a hollow tube having markings, wherein the hollow tube includes an internal end and an external end. The internal end includes one or more fins that can be manipulated into an open position and a closed position. The external end includes an opening allowing the insertion of a push-tube sliding axially within the body of the hollow tube, the push-tube being used to manipulate the fins into the open and closed positions. Further, an outer ring moves axially along the exterior of hollow tube and is utilized to measure the length of the urethra.

An intermittent catheter assembly and kit comprising an elongated introducer element formed of a flexible material adapted for insertion into a urethra during a catheterization procedure. The introducer element has at least one slit extending longitudinally along a substantial portion of its length. The catheter assembly also includes an applicator having an opening, and a sheath having a first end that is secured to the applicator about the opening. The sheath also has a second end defining a discharge opening which is inverted relative to the first end of the sheath to define inner and outer sleeve portions. The inner sleeve portion defines a flow path for urine through the discharge opening. The applicator receives the introducer element through the opening and extends the outer sleeve portion over an outer surface of the elongated introducer element to separate it from the urethra.

A urinary catheter assembly includes a catheter member and a sleeve member receiving at least a portion of the catheter member and having a greater flexibility than the catheter member. The assembly also includes a stylet having a proximal end movably positioned within the catheter member, with a distal portion of the stylet being positioned outside of the catheter member. The assembly is movable between a compact configuration and an extended configuration. In the compact configuration, the distal portion of the stylet is positioned outside of the catheter member and at least partially within the sleeve member. In the extended configuration, a larger distal portion of the stylet is positioned outside of the catheter member than in the compact configuration. The assembly may be in the extended configuration for introduction into a urethra or may be advanced through a urethra prior to being moved to the extended configuration.

A system suitable for collecting and transporting urine away from the body of a person or animal may include an assembly having a fluid impermeable casing, a fluid permeable membrane, and a fluid permeable support. A reservoir is defined by the fluid permeable support. The fluid permeable membrane can define a cavity. The casing can define an opening such that the cavity is accessible via the opening. The assembly can also include an outlet in fluidic communication with the reservoir. The assembly can be arranged such that a user's penis can be disposed through the opening with the urethral opening disposed within the cavity and such that a fluid can flow into the body from the urethral opening of the user's penis, collect in the reservoir, and flow out of the outlet.
