Tool for adjusting an implantable adjustable fluid flow control valve

An implantable medical device is disclosed that includes a valve seat and a valve member movable with respect to the valve seat. An adjustment circuit assembly includes a resistive element that is coupled to the valve member and operable to position the valve member relative to the valve seat so as to alter the pressure setting in response to a current applied to the resistive element.

A magnetic article with a corrosion resistant barrier formed from a poly (tetrafluoro-p-xylene) conformal coating or from a parylene conformal coating having a melting point of at least about 430&#xb0; C. and a moisture vapor transmission less than about 0.5 g-mm/m/day at 90% RH and 37&#xb0; C., the conformal coating being covered with a polysulfone thermoplastic overlayer.

A drainage system that includes a ventricular catheter, a drainage catheter, and a positive displacement pump that can function to actively drain CSF from the ventricles of the brain of a patient. The pump can include, for example, a diaphragm pump, a piston pump, a rotor pump, a peristaltic pump, or a screw pump.

Tools for determining and adjusting the setting of an adjustable valve are disclosed. These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

Drug loading of polymeric materials can be adjusted by selection of materials and/or adjusting processing steps in formation of an implantable drug-loaded device.
