摘要： Disclosed herein is an intravascular catheter system for crossing a severe or total arterial occlusion; particularly, a steerable intravascular catheter providing a working element and the optical guidance thereof in crossing an occlusion. Also disclosed is a method of crossing a severe or total arterial occlusion with a steerable catheter working element under optical guidance.

摘要： An intravascular catheter system for the treatment of occluded blood vessels that includes tissue displacement or hinged expansion members that are movable from a closed to an open position. An actuating assembly may be provided for moving the tissue expansion members between an open and closed position to exert a substantially lateral distal end force upon the region surrounding an occluded blood vessel. The tissue expansion members may stretch apart, tear or otherwise disrupt a vascular occlusion sufficiently to create a pathway that may support the passage or placement of a guidewire or an interventional vascular device across the occlusion or obstruction. Methods of crossing or displacing a vascular occlusion are further provided that include the positioning of a vascular catheter having at least one hinged spreading member positioned at the distal region of the catheter that is responsive to directed force along the longitudinal axis of the catheter. A directed force is applied to the actuator in order to deploy the spreading member and displace a vascular occlusion creating a path to permit the passage of a guidewire or device therethrough.

摘要： Disclosed herein is a blunt end assembly including a catheter and a blunt end member. The blunt end member includes jaw sections which have a first closed position for locating the blunt end member at the site of the occlusion within the native lumen of the blood vessel and a second open position wherein the jaw sections are able to press against the interior walls of the lumen adjacent the occlusion. The assembly includes an actuation member for moving the jaw sections from the closed to the open positions repeatedly resulting in a fracturing of the occlusion. A guide wire may be thread through an internal opening in the catheter and the blunt end member and after fracturing, across the occlusion.
