The invention relates to a wetting mechanism 20 for wetting a tube 12 of a catheter 10. The wetting mechanism 20 includes a housing 16 to be positioned at or proximal to the tip end 13 of the catheter tube 12, where the housing 16 comprises a holding chamber 22 and a wetting chamber 23. The wetting mechanism 20 comprises a fluid release control component 26 for controlling release of fluid within the holding chamber 22 into the wetting chamber 23. At least a portion of the catheter tube 12 is then able to be introduced and be moved through the wetting chamber 23 to wet the catheter tube 12, in use.

Disclosed herein is a catheter advancement device having an elongate shaft and a capsule attached to or integral with the shaft, and related methods for assisting with advancement of catheters such as cardiovascular guiding catheters while reducing damage to the inner wall of the blood vessel. Some capsules have a distal plug portion and a neck portion having a smaller diameter than the plug. Other capsules have a channel defined along the outer surface of the capsule. Some elongate shafts have an attachment tube disposed at or near the proximal end thereof.

Described herein is a liquid embolic delivery device designed to minimize excess embolic solvent buildup therein. The liquid embolic delivery device generally comprises an outer catheter, an inner catheter that is longitudinally moveable within the outer catheter. The inner catheter is used for an initial embolic solvent flush and to deliver liquid embolic, while the outer catheter is used to remove excess solvent.

An apparatus and methods are provided for a double balloon vascular occlusion catheter. The double balloon vascular occlusion catheter includes a catheter for reaching an injury site within an artery. The catheter includes a central lumen for receiving a wire to guide the catheter to the injury site. A distal aspect of the double balloon vascular occlusion catheter includes proximal and distal balloons for being inflated on opposite sides of the injury site. A space between the balloons provides a blood occlusion segment of the catheter when the balloons are inflated. Inflation tubes and luer-locks at a proximal aspect of the double balloon vascular occlusion catheter enable inflation of the balloons. The double balloon vascular occlusion catheter may include a bidirectional lumen that causes unobstructed blood flow to bypass the blood occlusion segment.

Methods and devices for controlling blood perfusion pressure along with regional mild hypothermia. In at least one embodiment of a device for controlling blood perfusion pressure within a vessel of the present disclosure, the device comprises an elongated body having a lumen, a proximal end configured for placement in a first area having a first blood pressure, and a distal end configured for placement in a second area having a second blood pressure, a partial occluder positioned within the lumen of the elongated body between the proximal end and the distal end, the partial occluder configured so not to fully occlude a blood vessel and to equalize the first blood pressure at the first area with the second blood pressure at the second area, and a regional hypothermia system operably coupled thereto, the regional hypothermia system operable to reduce and/or regulate a temperature of a bodily fluid flowing therethrough.

An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

A uniform internal diameter drainage system is disclosed. The system comprises a drainage catheter with large French drains and an internal diameter that progressively expands to a uniform internal diameter of the system. The catheter comprises a receiving port in fluid-tight communication with an engaging port of a hub, which comprises a first end, second end and flush port. The second end engages the catheter and the internal diameter of the catheter and the second end are substantially uniform. The first end comprises a receiving port that engages an engaging port of a drainage line and internal diameter of the drainage line and the first end of the system of the present invention are substantially uniform. A flush valve is disposed between the first end and second end of the present system to flush fluids from the system as needed.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

A suction catheter system is described with a suction extension interfaced with a guide catheter to form a continuous suction lumen extending through a portion of the guide catheter and through the suction extension. The suction extension can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. The suction extension can comprise a connecting section with a non-circular cross section for interfacing with the inner lumen of an engagement section of the guide catheter. Proximal fittings attached to the guide catheter can facilitate safe removal of the catheter system from the patient by allowing for the removal of some or all of a tubular extension of the suction extension from the guide catheter behind a hemostatic seal. The fittings can include a docking manifold that can dock the connection suction of the suction extension to allow removal of the suction extension from hemostatic isolation and clearing of clots from the suction extension without further fittings such that the cleared suction extension can be efficiently reinserted for additional use.

A device can be coupled to a foley catheter inserted into the bladder of a patient, where the foley catheter includes a urine passage through which urine can be drained from the bladder. The device includes a pressure sensor that is connected to a urine outlet of the urine passage and configured to measure a pressure value of the urine being drained through the urine outlet, a processor connected to the pressure sensor and configured to determine whether the foley catheter can be removed by comparing the pressure value and a predetermined threshold value, and a display unit connected to the processor and displaying whether the foley catheter can be removed according to the control of the processor.
