METHODS AND SYSTEMS FOR DISRUPTING CALCIFIED WALLS OF BIOLOGICAL CONDUITS AND CALCIFIED LESIONS THEREIN |
摘要 |
The present system is directed in various embodiments to rotational atherectomy systems and methods generally. More specifically, a method for methodically softening and otherwise disrupting calcification located within atherosclerotic plaque, lesion or occlusion and/or within the wall of a biological conduit or lumen. The softening and/or disruption of the calcification in the walls of the exemplary artery is accomplished in conjunction with abrading removal of any occlusion located on the interior surface of the exemplary artery and, therefore, located within the artery's lumen. This result is achieved by use of at least one eccentric head that, during high-speed rotation within the exemplary lumen, has been found to produce a combination of a low-frequency orbital motion comprising a force that is exerted against the lumen wall, with concomitant deflection of same, and/or a high-frequency pulsatile frequency, also with concomitant exertion of force against the lumen wall and deflection of same. |
