Abstract
A method system and controller for controlling fluid flow in a rotational atherectomy device. A source of fluid is provided through a pump to the rotational atherectomy device, wherein the pump maintains the fluid flow at a minimal rate during a time period when a drive shaft of the device is not rotating. A first control is activated to increase a rate of the fluid flow and second control is activate to initiate a rotation of the drive shaft during another time period when the fluid flow is at the increased rate.

88. A rotational atherectomy system comprising:
-
a rotational atherectomy device;
a fluid source adapted to supply fluid to the device;
a fluid pump system adapted to pump fluid from the fluid source to the device; and
a switching mechanism having at least a first mode and a second mode, the first mode adapted to change a state of the fluid pump from a static state to a dynamic state, and the second mode adapted to activate a rotation of a drive shaft in the device. - View Dependent Claims (89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101)
