What is the rotational speed of the blade in the Simpson atherectomy catheter?

Explanation:
Rotational speed determines how aggressively the device shaves plaque versus how much it risks damaging the vessel. The blade in the Simpson atherectomy catheter is designed to rotate at about 2,000 rpm. This moderate speed provides effective debulking of plaque while keeping friction, heat, and mechanical stress on the vessel wall at a safer level. It also complements the catheter’s debris management, helping to reduce distal embolization. If the speed were much higher, the risk of vessel injury or embolic complications would rise; if it were much lower, debulking would be less efficient. So, 2,000 rpm is chosen to balance efficacy with safety.
