摘要:
The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with a pre-curved abrasive section disposed within a catheter that deforms the abrasive section to a substantially straight profile and, when the abrasive section is moved distally out of the catheter, the abrasive section resumes its pre-curved profile. Directional ablation is achieved by rotation of the drive shaft along its pre-curved axis as the abrasive section is urged against a portion of the lumen wall.
