Integra NL8500312 Integra Mishler Dual Chamber Flushing Valve

VALVE FLUSH F/B D/C W/CONNECTORThe Integra Mishler Dual Chamber Flushing valve, Flat Bottom Design incorporates two separate interior chambers to provide two-way flow control when shunting cerebrospinal fluid (CSF) from the ventricles of the brain. This silicone elastomer flushing valve is available with or without an integral Anti-Siphon Device. The flat bottom configuration eliminates the need for a formal burr hole, provides greater latitude in positioning the flushing valve and allows the ventricular catheter to be revised without disturbing the flushing valve. Due to the dual chamber feature, the proximal and distal catheters may be flushed separately or simultaneously. The flow of CSF from the ventricular catheter is controlled by a miter valve located on the vertical chamber divider. This valve is designed to open under a medium positive ventricular pressure and close under a negative pressure. The flushing valve dome is marked with an arrow to indicate the CSF flow direction. The flange overlying the skull contains sutural holes to facilitate securing the device to the periosteum.
