1 Fluid flow through a shunt system should compensate for normal CSF production, as well as cerebrovascular induced ICP changes, in order to maintain intraventricular pressure within the target physiological limits, regardless of patient position. Our approach is intended to more closely restore the important balance between intracranial and cerebrovascular pressures and optimize patient care and treatment. Beverly Referential Valve A truly revolutionary valve system. Simple in concept. Sophisticated in design.
Solid shell minimizes the effect of tissue encapsulation on valve function.
The original flat bottom diaphragm CSF valve is now improved- another step forward in the treatment of hydrocephalus. The patented horizontally mounted valve mechanism allows for a more laminar flow path than other flat-bottom diaphragm valves. Newly designed proximal and distal occluders lead to a less torturous flow path than with previous occluder designs. Ridged valve housing protects against accidental needle damage to the valve mechanism. A polypropylene needle guard minimizes the potential of a needle penetrating the floor of the reservoir chamber.
