Abstract

A stylet for re-entry into a vessel includes an elongate body including a proximal portion, a middle curved portion, a pointed distal end, and a longitudinal axis extending through the proximal portion, the middle curved portion, and the pointed distal end. The proximal portion and the middle curved portion have substantially circular cross-sections. The middle curved portion has a pre-shaped curve along the longitudinal axis configured to match a curve of an occlusion-crossing device. The pointed distal end has an s-curve along the longitudinal axis and a flattened portion along the longitudinal axis, the flattened portion having a substantially oblong cross-section.
