A thrombectomy catheter, comprising: a catheter body extending from a catheter proximal portion to a catheter distal portion and including a catheter lumen (110, 112) extending between the catheter proximal portion and the catheter distal portion; a high pressure tube extending through the catheter lumen from the catheter proximal portion toward the catheter distal portion, the high pressure tube configured for communication with a fluid source near the catheter proximal portion; a fluid jet emanator in communication with the high pressure tube, the fluid jet emanator having at least one jet orifice for directing at least one fluid jet from said fluid jet emanator through the catheter lumen; an outflow orifice located along a catheter perimeter of the catheter distal portion; an entrainment inflow orifice positioned along the catheter distal portion; and an accessory device (400, 500) disposed within the catheter lumen, the accessory device comprising: an elongated member having proximal portion and a distal portion; and an expandable cage (404, 504) comprising a plurality of longitudinally extending struts, the expandable cage disposed adjacent to the distal portion of the elongated member such that a length of the distal portion of the elongated member extends distally beyond a distal end of the expandable cage; wherein the accessory device (400, 500) is configured to be operated to help aid in the disruption of the lesion. a catheter body extending from a catheter proximal portion to a catheter distal portion and including a catheter lumen (110, 112) extending between the catheter proximal portion and the catheter distal portion; a high pressure tube extending through the catheter lumen from the catheter proximal portion toward the catheter distal portion, the high pressure tube configured for communication with a fluid source near the catheter proximal portion; a fluid jet emanator in communication with the high pressure tube, the fluid jet emanator having at least one jet orifice for directing at least one fluid jet from said fluid jet emanator through the catheter lumen; an outflow orifice located along a catheter perimeter of the catheter distal portion; an entrainment inflow orifice positioned along the catheter distal portion; and an accessory device (400, 500) disposed within the catheter lumen, the accessory device comprising: an elongated member having proximal portion and a distal portion; and an expandable cage (404, 504) comprising a plurality of longitudinally extending struts, the expandable cage disposed adjacent to the distal portion of the elongated member such that a length of the distal portion of the elongated member extends distally beyond a distal end of the expandable cage; wherein the accessory device (400, 500) is configured to be operated to help aid in the disruption of the lesion. an elongated member having proximal portion and a distal portion; and an expandable cage (404, 504) comprising a plurality of longitudinally extending struts, the expandable cage disposed adjacent to the distal portion of the elongated member such that a length of the distal portion of the elongated member extends distally beyond a distal end of the expandable cage; wherein the accessory device (400, 500) is configured to be operated to help aid in the disruption of the lesion.
