1. A thrombectomy catheter system comprising:
- a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body includes;
an aspiration lumen extending though the catheter body to the catheter distal portion, a catheter body inner wall extending around the aspiration lumen, andan aspiration orifice at the catheter distal portion in communication with the aspiration lumen;
an infusion body including a fluid delivery lumen extending to at least one infusion orifice, the infusion body is within the aspiration lumen and extends through the aspiration orifice; and
a plug removal assembly coupled with the infusion body including;
an expanded member coupled to a distal end of the infusion body and located distally relative to the at least one infusion orifice, anda guide member coupled with the infusion body proximally relative to the expanded member, the guide member includes a guide outer perimeter corresponding to the catheter body inner wall, and the guide member is slidably coupled along the catheter body inner wall.

12. A thrombectomy catheter system comprising:
-
a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body includes an aspiration lumen and an aspiration orifice at the catheter distal portion in communication with the aspiration lumen; an infusion body including at least one infusion orifice, the infusion body is within the catheter body and extends through the aspiration orifice; a plug removal assembly coupled with the infusion body including; an expanded member coupled to a distal end of the infusion body and located distally relative to the at least one infusion orifice, and a guide member coupled with the infusion body proximally relative to the expanded member, and the guide member is slidably coupled along a catheter body inner wall; an infusion pump coupled with the infusion body, the infusion pump configured to provide a flow of infusion fluid through the infusion body to the infusion orifice; and wherein the expanded member is slidable between deployed and plunging positions relative to the aspiration orifice; in the deployed position the expanded member and the at least one infusion orifice are spaced from the aspiration orifice, and in the plunging position the expanded member and the at least one infusion orifice are within the aspiration lumen, and the guide member is configured to slidably guide the expanded member into the aspiration lumen from the deployed position to the plunging position, and the expanded member is configured to plunge thrombus plugs into the aspiration lumen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for using a thrombectomy catheter system comprising:
-
positioning a catheter distal portion of a catheter body adjacent to a thrombus in a vessel, the catheter body including an aspiration orifice at the catheter distal portion and an aspiration lumen in communication with the aspiration orifice; hydrodynamically removing the thrombus from the vessel with an infusion jet from at least one infusion orifice of an infusion body extending through the aspiration orifice, wherein the removed thrombus includes at least one thrombus plug larger than the aspiration orifice; and removing the at least one thrombus plug including; guiding an expanded member of the infusion body into the aspiration lumen with a guide member proximal to the expanded member on the infusion body, the guide member slidably coupled along a catheter body inner wall, plunging the at least one thrombus plug through the aspiration orifice into the aspiration lumen with the expanded member, and macerating the at least one thrombus plug within the aspiration lumen with the infusion jet from the at least one infusion orifice.
