Abstract: The guide catheter extension system for various intravascular procedures, including the reverse CART procedure, the thrombus removal, etc., has an enhanced ”capturing” capability. It is configured with a plastically expandable scaffold member forming an expandable “funnel-like” distal opening, and, once it has been advanced into the subintimal space, provides an enhanced capability of catching the retrograde wire or a thrombus, as required by the procedure. A balloon delivered to the target location in the blood vessel, by being inflated, opens the scaffold member to enhance the delivery of the retrograde wire or the thrombus into the guide catheter extension. When the guide catheter extension is no longer needed, the flared guide extension can be easily compressed and collapsed as it is drawn in the guiding catheter. For benefits of the thrombus removal, the balloon may be formed from a material loaded with a radiopaque material and prefabricated with micro pores.

Abstract: An improved medical device for revascularization of vascular occlusion and method for using same. The improved device includes a first catheter with a central lumen or guide wire capable of creating a channel within the CTO, and having a magnetic connection tip. One or more magnets or magnetic alignment elements are secured within or on the catheter connection tip to provide the desired positioning or straight line alignment of the catheter tip with respect to a second guide wire. The second guide wire includes a magnetic connection tip, with one or more magnets or magnetic alignment elements secured within or on the wire connection tip.
