ABSTRACT:
A vessel cleaning system for removing an obstruction from within a patient's vessel, the system comprising a housing, connected to a flexible-tube, a motor-driven flexible agitator-shaft rotatably disposed in the flexible-tube, and a flexible distal-agitator that is connected to the agitator-shaft and shaped so that it is asymmetrically offset to only one side of the longitudinal axis of the agitator-shaft. The agitator-shaft is extended from an open distal end of the flexible-tube to break the obstruction into pieces while rotating with an effective diameter that is larger than its cross-sectional diameter and the distal-agitator is made of a spiral wire, whereas the direction of its winding, relative to the direction of rotation, is such that the distal-agitator unscrews itself from tight engagements with its surroundings and automatically retracts into the flexible-tube.
