Abstract
A rotatable atherectomy device having an exchangeable drive shaft cartridge and a rotatable prime mover coupling. The cartridge has a rotatable drive shaft socket carried by a carriage. The coupling radially expands during rotation such that it interlocks with the socket to drive a tissue removal implement on the end of a drive shaft attached to the cartridge. Upon slow or no rotation of the socket, the coupling disengages from the socket to allow for exchange of the cartridge.
