Abstract
A single operator exchange fluid jet thrombectomy method employing a single operator exchange fluid jet thrombectomy device having an outer catheter assembly and separable and exchangeable components in the form of an inner catheter assembly allowing functioning as a rheolytic thrombectomy catheter or as a crossflow thrombectomy catheter. The outer catheter assembly is common to any mode of usage and includes a guide catheter having a lumen through which a guidewire and the greater portion of a hypo-tube carrying a jet emanator and a flow director are passed and advanced. In the method, thrombus is dislodged, entrained, and broken into pieces by fluid jets and evacuated through the lumen of the guide catheter.
