Abstract: Thrombectomy systems including a stroke length detection assembly. An illustrative drive unit for a thrombectomy system may comprise one or more panels enclosing an internal structure of the drive unit, a vertically oriented reciprocating linear actuator assembly extending between one or more support structures in an upper region of the drive unit and including a reciprocating linear actuator secured to a mounting plate and an actuator shaft, a bracket including a first portion extending generally parallel to a longitudinal axis of the actuator shaft and a second portion extending generally orthogonal to the longitudinal axis of the actuator shaft, the second portion coupled to the actuator shaft, a magnetic strip affixed to a surface of the first portion of the bracket, and a magnetic sensor positioned adjacent to a first end region of the bracket. The magnetic sensor may be configured to determine a relative position of the actuator shaft.
