Abstract
A thrombectomy catheter includes a catheter body having first and second lumens formed therein, and a flow directing mechanism upon a distal body end forming a channel for conveying fluid between an outlet and an inlet fluidly connected with the first and second lumens. The channel axially and circumferentially advances about the catheter body, and is positioned between the outlet and inlet such that fluid conveyed by the channel enters a suction stream flowing to the inlet and entraining material of disrupted thrombus.
