Comparison of a new recirculation thrombectomy catheter with other devices of the same type: in vitro and in vivo evaluations.

Rationale And Objectives: To compare a new 7 Fr. Helix thrombectomy catheter with Amplatz thrombectomy devices (ATD) with respect to clot fragmentation efficiency, hemolytic potential, and risk for vascular trauma.

Materials And Methods: Particle size was evaluated following the maceration of 8-to-10-day-old clots, each weighing 6 +/- 0.
