Interventional wire capture device and methods of use

Abstract

Disclosed herein are methods of traversing a chronic total occlusion (CTO) that include advancing a recanalization wire through the vasculature of the subject through a puncture site in an artery of a lower extremity towards a distal cap of the CTO, advancing the recanalization wire through the CTO until a distal tip of the recanalization wire exits the CTO via a proximal cap of the CTO, magnetically capturing the distal tip of the recanalization wire, pulling the recanalization wire through a puncture side in a femoral artery, thus externalizing the recanalization wire. Some capture wires may include a magnetic tip, such as a neodymium tip.
