1. A system comprising:
a sheath;
a laser catheter configured to receive laser energy, the laser catheter configured to move relative to the sheath, wherein the laser catheter comprises a distal tip, and wherein the sheath or the laser catheter comprises a sensor configured to sense a position of the distal tip of the laser catheter; and
a controller comprising a non-transient, tangible computer readable medium including logic, whereupon execution of the logic, the controller is configured to:
monitor an output of the sensor to determine a rate of manual advancement or removal of the laser catheter by an operator of the laser catheter;
compare the determined rate of with at least one threshold movement rate;
when the determined rate of movement falls outside the at least one threshold rate of movement, controlling
receive a selection signal configured to place the controller in an assisted mode or an unassisted mode;
(A) when the selection signal places the controller in the assisted mode, the controller is configured to monitor an output of the sensor to determine a manual and unregulated rate of advancement or removal of the laser catheter by an operator of the laser catheter, and in response to a determination that the manual and unregulated rate of advancement or removal falls outside a threshold range, to automatically regulate the rate of advancement or removal of the laser catheter; and
(B) when the selection signal places the controller in the unassisted mode, the controller is configured to monitor an output of the sensor to determine a manual and unregulated rate of advancement or removal of the laser catheter by an operator of the laser catheter, and in response to a determination that the manual rate of advancement or removal falls outside a permissible threshold, to generate an operator alert without automatically regulating the rate of advancement or removal of the laser catheter.
