Fly by wire control for atherectomy

An atherectomy system that is adapted for both anterograde direction ablation and retrograde direction ablation, the atherectomy system comprising:

• an operator assembly including:
• a user interface that an operator engages with in order to indicate requested translation of a drive assembly, the user interface configured to output a request signal indicating requested translation of the drive assembly;
• a first controller operably coupled with the operator assembly and adapted to receive the request signal from the user interface;
• and
• an advancer assembly including:
• a drive assembly adapted to translate relative to the advancer assembly, the drive assembly including:
• a drive shaft operably coupled with the drive assembly such that the drive shaft translates with the drive assembly;
• a drive motor adapted to rotate the drive shaft at atherectomy speeds;
• and
• an atherectomy burr coupled to the drive shaft;
• one or more sensors adapted to ascertain one or more conditions of the drive assembly and to output one or more condition signals;
• a second controller operably coupled with the operator assembly and the drive assembly, the second controller adapted to:
• receive the request signal from the first controller and the one or more condition signals;
• determine a command signal in response to the received request signal and the received one or more condition signals;
• and
• provide the command signal to the drive assembly;
• wherein the drive assembly is adapted to translate relative to the advancer assembly in accordance with the command signal.
