Zusammenfassung:	A catheter used for percutaneous endovascular procedures is described. The catheter is configured to be used for engagement and treatment of obstructive lesions in a patient's vasculature. The catheter includes a tube having a leading edge that is configured to score or cut a lesion in a vasculature. The tube may be an expandable outer tube, and placed around an inflatable inner tube, such that inflation of the inner tube expands the outer tube. Expansion of the inner tube may connect or laterally lock the inner tube to the outer tube, allowing both tubes to move in unison through the vasculature. The leading edge can score or cut lesions as it moves in the vasculature.
