The present invention provides a novel shunt device and methods of use, and in particular a cerebral shunt device. The cerebral shunt device includes an outer tube member forming a first lumen, the outer tube member having a drainage outlet and at least one opening to the first lumen in a distal region along the length of the outer tube member. The shunt also includes an inner tube member forming a second lumen, the inner tube member having at least one opening to the second lumen along the length of the inner tube member. The inner tube member is positioned within the first lumen and a pump unit fluidly connected to the second lumen to force fluid from the first lumen, which clears obstructions in the shunt.

Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

A distal end portion of an elongate shaft member of a catheter may be inserted into a liquid within a vessel. While the distal end portion of the elongate shaft member is inserted in the liquid in the vessel, a manipulable portion of the catheter may be manipulated within the liquid to remove an undesired fluid therefrom. The liquid may be pressurized to cause the liquid to flow into a lumen of the elongate shaft member from a distal end of the elongate shaft member at least toward a proximal end of the elongate shaft member to facilitate flushing of the undesired fluid from the lumen. The distal end portion of the elongate shaft member of the catheter may be inserted into the liquid within the vessel while at least the elongate shaft member is in a substantially horizontal orientation.

An aspiration system comprises an aspiration catheter, an aspiration source fluidly coupled to the aspiration catheter to create an aspiration flow path between the aspiration catheter and the aspiration source, a pressurized fluid source, and a passive pressure oscillation assembly fluidly coupled between the pressurized fluid source and the aspiration flow path. The passive pressure oscillation assembly is configured for being operated between a normal mode that prevents fluid communication between the pressurized fluid source and the aspiration flow path, and an oscillatory mode that pulses fluid communication between the pressurized fluid source and the aspiration flow path. The passive pressure oscillation assembly is configured for being triggered to switch from the normal mode to the oscillatory mode in response to a clog in the aspiration catheter.

A closed suction system module is provided. In one embodiment, the closed suction system module includes a coupling member configured to couple to a suction port of a multi-port manifold or endotracheal tube adapter (e.g., dual-port or tri-port adapter). In one embodiment, the closed suction system module includes a suction catheter configured to clean the interior surfaces of body-inserted tubes or artificial airways (alone or in addition to suctioning natural airways or portions of the respiratory tract or other body lumens). The suction catheter may include a cleaning portion at a distal portion of the suction catheter (e.g., near the distal end or tip of the suction catheter). In some embodiments, the cleaning portion includes at least one expandable cleaning member (e.g., balloon, sleeve, wiper).

An endovascular occlusion device. The endovascular occlusion device (300) has a balloon (306) and a catheter (304). The catheter (304) has a distal end (308), a proximal end, and a lumen (318) extending therebetween. The balloon (306) is positioned proximate to the distal end (308) of the catheter (304) and has a deflated state and an inflated state. The catheter (304) further includes a plurality of ports (314) proximate to a proximal end of the balloon (306). Each port (314) extends through a wall of the catheter (304) such that surface (316) of the catheter (304) is in fluid communication with the lumen (318) of the catheter (304). A flow restrictor (324) is positioned within, and is in sliding relation with, the lumen (318) of the catheter (304). Movement of the flow restrictor (324) is configured to close one or more ports (314) of the plurality so as to limit blood flow through the lumen (318) of the catheter (304).

A catheter has an elongate shaft with a longitudinal drainage bore for conveying fluid along the shaft. An elongate, tapered tip portion extends from an end of the shaft, the tip portion having a distal end furthest from the shaft, and a drainage aperture is provided in the tip portion, being in fluid communication with the bore. An inflatable balloon element is attached to the tip portion. The balloon element is configured such that when it is fully inflated, at least a portion of the balloon element extends around the distal end of the tip portion and extends along the tip portion to a point on an opposite side of the drainage aperture to the distal end, a surface of the balloon element including a depression providing a passageway in fluid communication with the drainage aperture.

Devices for cleaning a tube or clearing a blockage from a tube, such as an enteral feeding device are provided. The devices include an actuator and a syringe. The actuator is releasably attached to the syringe in a manner that allows the actuator to transition the syringe from a compressed position to an extended position, and vice-a-versa, without requiring the intervention of a user. A method of cleaning a tube or clearing a blockage in a tube is also provided. The tube cleaning device is filled with a liquid and the actuator pushes the liquid from the syringe into the tube when transitioning into a compressed position, and withdraws the liquid back into the syringe when transition into an extended position, causing the liquid to contact a blockage, and clear the blockage and/or clean the tube.

Method for preventing biofilm formation on at least one luminal surface of a catheter system (1). The catheter system (1) comprises a collection vessel (4) and a tube (3) coupled to the collection vessel (4). The catheter system (1) comprises a catheter connector (2, 20, 200) coupled to the tube (3) and connectable to a catheter (6). The method comprises the consecutive steps of connecting the catheter connector (2, 20, 200) to the catheter (6) and supplying a silicon oil to an interior (25, 205) of the catheter connector. A catheter assembly comprising a catheter connector (20) comprising a port (24) providing access to the interior (25) of the connector and a dispensing unit (50) containing a silicon oil. A catheter connector (200) comprising a reservoir (207) containing a silicon oil and a releasing mechanism (208) releasing the silicone oil into the interior (205) of the connector.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.
