• identifying, using the processing circuitry, at least one deviation from the established baseline of the one or more operational parameters of the separator instrument wherein the identifying comprises determining that one or more torque measurement values determined from the signal are anomalous relative to a baseline torque comprising the established baseline of the one or more operational parameters;
• determining, using the processing circuitry, that the identified at least one deviation corresponds to at least one engagement condition of the separator instrument, wherein determining the at least one engagement condition of the separator instrument comprises distinguishing the anomalous one or more torque measurements between being caused by an occlusion in a vasculature or being caused by something other than an occlusion;
• and
• causing, using the processing circuitry, an action to be performed based on the determining.
