Motors for Peripheral Artery Disease Treatment


Peripheral Artery Disease Treatment Devices

Maintaining proper blood flow is critical for tissue oxygenation. When blood flow is obstructed, discomfort, loss of limbs and even death can occur. Orbital and rotational atherectomy procedures cut or grind away calcified plaque to restore blood in diseased vessels. There are many different motion approaches to atherectomy. Some devices rotate at very high speeds and grind plaque away, while some devices rotate more slowly and cut plaque. Portescap’s wide miniature motor portfolio contains the right medical motor solution for all atherectomy approaches. While coreless brush DC motors enable high efficiency and torque for battery-operated disposable devices, brushless motors allow for smooth high-speed and high-torque operation.
