Abstract: A tourniquet apparatus comprises a cuff, a user interface, a controller, a protocol hazard key and a protocol safety interlock. The cuff encircles the patient's limb and applies a level of pressure. The UI presents a protocol symbol from a plurality of protocol symbols wherein each protocol symbol is indicative of a corresponding safety protocol. The controller is responsive to stored pressure levels and stored times specified by the safety protocol, after any adjustments by the user, and operable during the stored protocol time period for maintaining the level of pressure applied by the cuff to the individual patient near the plurality of stored pressure levels at the plurality of stored times. The protocol hazard key is actuatable to end the stored protocol time period while the controller is operable. The protocol safety interlock prevents selection of a second protocol symbol while the controller is operable.

Abstract: An atherectomy system includes a handle and a drive motor that is adapted to rotate a drive cable extending through the handle and operably coupled to an atherectomy burr. A control system is adapted to regulate operation of the drive motor, including providing the drive motor with a high frequency pulse width modulation (PWM) drive signal in order to operate the drive motor. The control system monitors a motor performance parameter such as motor speed or motor torque, and when the motor performance parameter approaches a limit of a performance range, the control system adds a low frequency PWM signal to the high frequency PWM drive signal, thereby causing the drive motor to produce a tactile signal that signals to the user that the motor performance parameter is approaching the limit of the performance range.
