Abstract

Models, Theoretical Viscosity Animals Cerebrospinal Fluid Shunts - methods Hydrocephalus - physiopathology Hydrocephalus - surgery Rheology Humans Cerebrospinal Fluid - physiology Cerebrospinal Fluid Pressure
Accurate in vitro measurements of the pressure drop-flow (drainage) rate relationship were made for perforated Teflon microtubules using a fish hook arrangement. These measurements indicated that appropriate drainage rates could be obtained in the physiological range for hydrocephalus shunts. Animal experimentation is required for in vivo evaluation of these microtubules with micron-sized holes that may prevent cellular ingrowth and recurrent obstruction, and thus extend implanted shunt life.
