摘要:
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. The magnets or magnetic alignment elements on each connection tip are arranged such that opposite polarity magnets are used to attract the magnetic tips and their respective wire or catheter into the occlusion or subintimal space and into a close proximity position and alignment within the vessel to enable the use of mechanical elements, wires, energy sources, laser sources, or combinations of thereof, to assist in crossing the occlusion by creating a channel.
