Abstract: Thrombectomy catheter systems, accessory devices, and methods for making and using such devices are disclosed. An example thrombectomy system may include a catheter shaft having a proximal portion, a distal portion, and a lumen extending at least partially through the catheter shaft. A high pressure tube may be disposed within the lumen. The high pressure tube may be designed for communication with a fluid source. A fluid jet emanator may be coupled to the high pressure tube. The fluid jet emanator may have at least one jet orifice. The catheter shaft may include a first orifice disposed proximally of a distal end of the catheter shaft and a second orifice disposed proximally of the first orifice. An accessory device may be disposed within the lumen. The accessory device may include a helical distal region.
