The Arrow Trerotola Percutaneous Thrombolytic Device (Product Codes: PT-65709-WC, PT-65709-W, PT-65709-HFWC, and PT-12709-WC) consists of a catheter with an expandable fragmentation basket attached to a through lumen torque cable and an outer catheter sheath. The catheter is used in conjunction with a low-speed, battery operated rotator unit to treat thrombosed hemodialysis grafts and AV fistulas. The macerating mechanism is done by 9 mm basket (made up of four stranded stainless steel wires) that rotates at 3000 rpm when rotator is activated. The current device is 7 Fr in size and comes in two lengths -- 65 cm and 120 cm. This device is used by inserting the catheter into the occluded graft or fistula via introducer sheath and then activating the rotator unit.
