Abstract

This work presents the design of a mechanical vasoconstriction mechanism with application for cerebral autoregulation. The relationship between the applied voltage of a DC motor and the tension within a pressurized vessel wall was utilized for constricting an arteriole segment within an intracranial vascular model. Using current proportional to the string tension, options for closed loop feedback control are considered.
