  • Patent number: 9936970
    Abstract: The present invention is directed in various methods, devices and systems relating to rotational atherectomy. More specifically, an oscillating driver is connected to a drive shaft, or torque transfer tube, with abrasive element mounted thereon. The result provides a rotational working diameter for the rotating abrasive element that is larger than its resting diameter. Generally, the preferred abrasive element is concentric in profile and/or with center of mass collinear with the drive shaft's rotational axis. However, eccentric abrasive elements, both in terms of offsetting center of mass and/or geometric eccentricity may also be employed.
    Type: Grant
