Abstract
An angioscope has irrigation system with at least two presettable irrigant flow rates. A footswitch under manual control is operatively connected to a roller pump for switching from a high first flow rate to a low second flow rate. Upon an initial filling of a blood vessel under observation with clear irrigant at the high flow rate, the operator switches to the low flow rate. The rate of fluid flow may alternatively be continuously variable under manual control.
