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

Methods and devices are provided that allow a physician to consistently and reliably locate an implantable, magnetically settable valve (valve) and to determine and/or change (adjust) a setting of the valve from a current setting to a target setting without interference from the valve and/or patient's skin. In particular, various locator tools are provided that include a housing having a deck extending thereacross that is formed at least in part of a material which is moveable to accommodate a protrusion of a hydrocephalus valve beneath skin.

Methods and devices for locating and adjusting an implantable 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

A two-part tool for reading and adjusting an implantable valve, and methods of use. The tool includes a locator-indicator component that, when placed matingly on the patient's skin over the valve, provides magnetic reading of the valve setting. The tool also includes an adjustor component that couples to the locator-indicator component and is rotatable to change a valve setting.
