A shunt includes a housing having an inlet, an outlet and a flow control mechanism disposed within the housing. A ventricular catheter is connected to the inlet of the housing. The catheter has a longitudinal length, a proximal end, a distal end, and an inner lumen extending therethrough. The inner lumen of the catheter includes at least two lumens at the distal end and has only one lumen at the proximal end. The catheter has one slit and aperture corresponding to each of the at least two lumens located at the distal end of the catheter.

Multi-lumen ventricular drainage catheter

An adjustable height tool for locating a magnetically readable and settable valve which includes a wall having a first perimeter. A platform can be disposed within the first perimeter. A valve cut-out can disposed within the platform and receive at least a portion of the valve. A movable foot can be disposed below the platform by which a displacement element moves the foot at least one of toward or away from the platform, in fixed increments of about 1.5 mm, upon rotation of the displacement element. This movement increases or decreases the distance between the platform and the skin/valve.

Adjustable height hydrocephalus valve location device

A method and toolset capable of remotely moving a rotor of an implanted device in a first arcuate direction and detecting a first limit of travel, moving the rotor in a second, opposite direction and detecting a second limit of travel without altering the current performance setting of the implanted device, comparing the first and second limits of travel with known values for a plurality of selectable performance settings, and indicating the current performance setting of the implanted device.

Method and tools for implanted device

A pressure sensing apparatus has a pressure sensor component that includes a pressure sensing port, a pressure sensor for sensing a pressure of a fluid in the pressure sensing port, and a digital processor communicating with the pressure sensor for performing calculations involving fluid pressures sensed. The pressure sensing apparatus further includes a first chamber in fluid contact with the pressure sensing port, a second chamber fluidically connectable with a patient's cerebrospinal fluid system, and a membrane located between the first and second chambers so as to transmit fluid pressure from the second chamber to the first chamber.

System and method for measuring the pressure of a fluid system within a patient

An anti-siphon drainage device having a housing forming an internal chamber, an inlet and outlet ports part of the internal chamber and fluidly connected by a primary flow path. A valve seat is associated with the primary flow path, a sloped section extends from the valve seat, and a valve element disposed in the sloped section and can seat in the valve seat to restrict a fluid flow into the primary flow path from the inlet port. A secondary flow path can have an opening near the inlet port and an orifice near the outlet port. A regulator has an aperture to selectively open and close the opening of the secondary flow path. When the valve element is seated in the valve seat and restricting the fluid flow into the primary flow path, the fluid flows into the secondary flow path.

Adjustable resistance, gravitationally activated, anti-siphon valve

A tool includes a locator having a center aligned with a rotor axis when disposed over the valve. The locator has a first dimension approximately perpendicular with the rotor axis. A wall of the locator forms a volume to allow an adjustor to be disposed therein. The adjustor fits within the wall and has a magnet having a magnetic axis to unlock the rotor. An adjustable outer wall has a first position dimension permitting the adjustor to rotate about the center of the locator and aligning the magnetic axis with the center. The adjustable outer wall has a second position dimension less than the first dimension and the first position dimension. The adjustor can move lateral, rotational, and orbital in the locator misaligning the magnetic axis with the center. Misaligning the magnetic and rotor axes unlocks the rotors and the magnet maintains the unlocked state even when the axes are misaligned.

Dynamic adjustment tool for programming an implantable valve

An adjustable height tool for locating a magnetically readable and settable valve implanted in a living being. The locator can include a wall having a first perimeter. A platform can be disposed within the first perimeter. A valve cut-out can disposed within the platform and can approximate at least a portion of the shape of the valve. A movable foot can be disposed below the platform by which a displacement element moves the foot at least one of toward or away from the platform. This movement increases or decreases the distance between the platform and the skin/valve. Two or more recesses can be disposed in the foot and the recesses can be aligned with the valve cut-out. The displacement element can maintain the alignment of the recesses and the cut-out while moving the foot.

An implantable valve system and method of using same, including a housing with a resilient membrane defining a reservoir in fluid communication with at least two ports, and at least a first set of opposing sealing features disposed on upper and lower surfaces within the housing. The membrane is capable of being depressed by a human finger to bring the sealing features together to substantially restrict fluid from passing through at least one of one of the ports, and is capable of being depressed additionally by a rolling motion of the finger to drive fluid through the other of the ports.

Valve system and method with multi-directional pumping

Adjustable resistance, gravitationally activated, anti-syphon valve

A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.

Implantable adjustable valve

A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows the lumen portion to rotate independent of the threaded portion.

Multiple lumen sensor attachment

An acoustic monitoring system that is able to verify the success or failure of the positional adjustment of a valve without the need for additional energy during non-invasive reprogramming is provided. The acoustic monitoring system includes a programmer for generating a sequence of commands to adjust the valve mechanism, and for receiving acoustic signals for analysis, a transmitter to implement the command and adjust the valve, and a sensor for detecting an acoustic signal generated from the valve during execution of the commands. A method for using the acoustic monitoring system is also provided.
