    摘要： A method 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 activated to initiate a rotation of the drive shaft during another time period when the fluid flow is at the increased rate.

    摘要： A rotational atherectomy device having an improved optical tachometer which uses a single, monofilament optical fiber to both transmit light from a light source to a light reflector and to return reflected light to a light detector. A fiber optic connector which can be used with such a rotational atherectomy device permits one to releasably optically couple a distal end of an optical fiber to both a light source and a light detector via a beam splitter and a flexible light guide. This fiber optic connector may include a pneumatic clamp which is connected to the same source of compressed gas which drives the prime mover of the rotational atherectomy device.
