摘要
The invention, in various embodiments, mounted on the drive shaft, are close spaced apart from the proximal and distal cone segment comprises at least one eccentric abrasive cylindrical segment, flexible comprise eccentric polishing head rotary atherectomy system having a sexual elongate rotatable drive shaft, to provide devices and methods. Each individual abrasive segment, the first tissue removal surface, typically, so as to polish is designed to polish the hard tissue calcification, and abrasive coating on the outer surface, the soft tissue that is not calcified It is designed, and a polishing coating on front and rear surfaces. Each polishing division, and a polishing head having a collective indicator has a center of mass spaced radially from the rotational axis of the drive shaft, if it is operated at high speed, up to a diameter larger than the outer diameter of the enlarged polishing head to promote the ability of the device to open the stenotic lesion.
