The present disclosure provides a method and apparatus for draining. The apparatus includes a body, the body having a first compartment adjacent to a second compartment, the first compartment having an inlet port fluidly connected to an outlet port, the inlet port defining a needle seat within the first compartment, a first rod hole for operation with a second rod hole in the second compartment, and a plurality of venting holes, the second compartment having a plurality of spaced notches along. The apparatus further includes a setting rod, the setting rod having a shaft and a sealing head, the shaft sized to be slideably maintained in the first rod hole and the second rod hole, the sealing head slideably attached to an end of the shaft and sized to obstruct fluid flow from the inlet port at the needle seat.

Disclosed herein is ureteral stent. The ureteral stent includes a proximal end, a distal end, and a middle portion. The proximal end includes a retention feature having a coiled shape. The distal end is opposite the proximal end. The middle portion is between the proximal end and the distal end.

An implantable occlusion and tissue ingrowth resistant fluid interface is provided with a housing, an orifice and a catheter port. The housing is formed from at least one biocompatible material and is configured without sharp edges or corners. The housing at least partially defines an internal housing cavity. The orifice member at least partially defines an orifice between the internal housing cavity and an exterior of the housing. The orifice has an elongated transverse cross-section configured with a length that is at least four times its maximum width. The catheter port is located on the housing and is configured to couple with a catheter such that the internal housing cavity is in fluid communication with a lumen of the catheter when the catheter is coupled to the catheter port. Embodiments having a moving cylinder, a rotor, and non-chemical surface modifications, as well as methods of use are also disclosed.

The present invention relates to a transcatheter method for providing fluid communication between two anatomical compartments. The present invention also relates to a transcatheter system comprising an intracorporeal connector for fluid communication between two anatomical compartments through at least one anatomical wall, wherein said connector is adapted to receive a flow regulating device, a connector, a flow regulating device and an insertion device.

A drainage or infusion catheter and methods of use are disclosed. In one embodiment, the catheter includes a tube body having a proximal end and a distal end, and a plurality of ports arranged along the tube body from the distal end to the proximal end. The distal end of the tube body is configured to deform around itself into a substantially spiral shape so as to cover at least one of the plurality of ports located near the proximal end of the tube body. In another embodiment, a flap is configured to erupt from apertures arranged in the tube and extend outwardly around the tube body so as to cover at least one of the plurality of ports located near the proximal end of the tube body.

An apparatus for performing cerebral micro-dialysis to treat neurological disease of a patient's brain includes a catheter for implantation in or near the patient's brain, an implantable pump communicated with the catheter to transport cerebrospinal fluid (CSF) from the patient, which CSF contains diseased cells or biomolecules associated with the neurological disease, and an implantable separation device communicated with the pump wherein the diseased cells or biomolecules are removed, where the separation apparatus includes a dialysis membrane impregnated with an antibody, a reversible electrostatic filter, and/or a magnetic field effect fractionation chamber wherein a magnetically-tagged antibody scavenges and aids in the removal of circulating diseased cells or biomolecules from the CSF.

Drainage systems for excess body fluids and associated methods are disclosed herein. A body fluid drainage system in accordance with an embodiment of the present technology, for example, can include a catheter that has an exterior surface, a proximal portion, and a distal portion opposite the proximal portion. The body fluid drainage system can further include a valve device, a pressure sensor, and a controller operatively coupled to the valve device and the pressure sensor. The valve device can include an actuator positioned over the exterior surface of the catheter. The actuator is movable between an open position that allows body fluid flow through the catheter, a closed position that at least substantially obstructs the body fluid flow through the catheter, and intermediate positions that partially obstruct the body fluid flow through the catheter. The controller can change the position of the actuator in response to a predetermined condition of the pressure sensor.

A self cleaning inlet head for use on a shunt. The head has a tube with openings disposed in predetermined positions in its wall, and a cleaning element installed inside the tube. The cleaning element may comprise a central shaft with a number of bristles protruding therefrom, preferably in locations substantially identical to the positions of the openings in the wall of the tube. Mutual vibratory motion between the cleaning element and the tube causes at least some of the bristles to enter the openings, thereby keeping them clear, and preventing tissue growth into them. The vibratory motion may be generated by the action of an external field on a responsive part of the cleaning element, such as an external magnetic field operating on a magnetic or magnetized part of the cleaning element or the bristles. Alternatively, the external field may be an ultrasound field operating on the bristles.

A device for use in pressure sensing has a housing enclosing a chamber and having at least one port that communicates with the chamber. A pressure sensor receives fluid pressure from the chamber. The chamber has a compliance that exhibits a marked change in volumetric stiffness repeatably at a fixed pressure.

The present technology is generally directed to shunting systems, including shunting systems having a shapeable/conformable elongated housing or shunting element that can be contoured or otherwise selectively shaped to improve a fit with patient anatomy. The shunting systems and elongated housings described herein can have numerous other advantageous features expected to improve the operation of shunting systems, such as beveled leading edges, lateral outlets, suture rings, positioning appendages, and the like.
