Latest Patents

Larry A. Waller holds a patent for a "Multi-material abrading head for atherectomy devices having laterally displaced center of mass." This patent describes an abrading head designed for high-speed rotation atherectomy devices. The head features a center of mass that is laterally displaced from the rotational axis of the drive shaft. As the drive shaft spins, centrifugal force pushes the abrading head outward. This design allows the abrasive portion of the head to cover a larger area at high speeds compared to lower speeds or when at rest. The abrading head consists of two components with different densities. The connection portion, which attaches to the drive shaft, may be made of a low-density metal like stainless steel. In contrast, the eccentric portion is typically made of a high-density metal such as tungsten or tantalum. This configuration provides a greater separation between the center of mass of the abrading head and the rotational axis of the drive shaft, enhancing its performance.
