ATHERECTOMY SYSTEM WITH DIRECTION-SPECIFIC STALL STOP MECHANISM

This abstract first appeared for US patent application 20250134549 titled 'ATHERECTOMY SYSTEM WITH DIRECTION-SPECIFIC STALL STOP MECHANISM

Original Abstract Submitted

an atherectomy system includes a housing and a drive mechanism disposed within the housing, the drive mechanism including a knob that allows translation of the drive mechanism relative to the housing. a sensor is adapted to detect a current position of the knob relative to the housing. a controller is adapted to utilize the signal representative of the current position of the knob to ascertain whether the drive assembly is moving in a direction indicative of anterograde ablation or a direction indicative of retrograde ablation. a stall stop mechanism is adapted to move the drive assembly in a direction opposite a direction of ablation when a stall is determined to be imminent. the controller is further adapted to determine when a stall is imminent, and to actuate the stall stop mechanism in an appropriate direction when a stall is imminent.
