An implantable bodily fluid drainage system including a collection vessel and a mechanical volume limiting mechanism for preventing overfill of the collection chamber. The mechanical volume limiting mechanism is not susceptible to malfunction if immersed in the bodily fluid. Moreover, the volume capacity of the fluid collection chamber is adjustable in addition to the overfill prevention functionality.

Bodily fluid drainage system with volume limiting and adjustable volume capacity functionality

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

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.
