Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imageable portions (e.g., portions which are visible under magnetic resonance imaging (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked. Systems and methods for flushing a shunt system are also disclosed herein, as are various systems and methods for opening auxiliary fluid pathways through a shunt system.

Systems and methods for shunting fluid

A device for use within a woman's urethra for obstructing urine outflow when the pressure in the woman's abdomen is at or above a threshold pressure level (IAP1). The device also allows urine outflow when the intra-abdominal pressure is below the threshold pressure level (IAP1). The device includes a flexible tube that is configured to be inserted into a urethra, wherein the tube defines a lumen that has inlet and outlet openings. The tube is configured to receive, conduct and discharge urine. The tube is further configured such that the lumen is at least partially obstructed when the pressure on the urethra surrounding the tube at least meets the threshold pressure (IAP1), and the lumen is more open when the pressure on the urethra surrounding the tube is at a level below a second, lower, threshold pressure (IAP2).

System and methods for shunting fluid

A drug-delivery cannula assembly includes a cannula housing adapted for receiving at least one obturator shaft of an obturator assembly therethrough, one or more cannulae, and a supply line coupled to the cannula housing. The cannula housing is adapted for receiving one or more obturator shafts of an obturator assembly therethrough. The one or more cannulae define a longitudinal axis and a passageway aligned with the longitudinal axis. The one or more cannulae each include a proximal end coupled to the cannula housing. The cannula housing is configured to fluidly-couple the one or more cannulae to a source of a drug delivery supply for supplying drugs via the supply line to the one or more cannulae.

Drug-delivery cannula assembly

A drug-delivery device includes a body configured for attachment to a handle of an ablation device, a shaft portion defining a passageway therein, and a delivery lumen to provide for drug delivery to tissue. The body includes a proximal portion, a distal portion, and a contoured portion disposed therebetween. The contoured portion is configured for engagement with a contoured portion of the handle of the ablation device. The shaft portion includes a proximal end and a distal end. The proximal end of the shaft engages with an opening defined in the distal end of the body. The passageway of the shaft portion is configured to receive the delivery lumen slideably moveably therein. The delivery lumen includes a proximal portion and a distal portion. The drug-delivery device also includes a knob member coupled to the proximal portion of the delivery lumen.
