Which of the following thrombectomy devices fragments and removes emboli but produces hemolysis?

The Helix "Clot Buster" thrombectomy device is designed to fragment and aspirate thrombus material from the vascular system effectively. One distinctive feature of this device is its mechanism, which involves the rapid rotation of a helical cutter. While this method is highly effective in breaking up clots, it can also induce hemolysis, which is the destruction of red blood cells. This hemolysis occurs because the mechanical action of the device can shear red blood cells in the process of clot fragmentation and removal.

The ingenuity of the Helix device lies in its ability to both fragment emboli and use aspiration to remove the debris, which can lead to the release of free hemoglobin into circulation and result in hemolysis. This aspect is critical in understanding its clinical application and potential complications. Therefore, when considering thrombectomy devices, it's essential to recognize that while some may be effective in removing thrombi, they can also produce adverse effects, such as hemolysis, as seen with the Helix "Clot Buster."
