Zusammenfassung: | An occlusion bypassing apparatus for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The apparatus includes an outer shaft component having a needle lumen there-through. A proximal end of the outer shaft component is fixed within a handle of the apparatus at a first attachment point. A stabilization tube of the apparatus is disposed within the needle lumen. A proximal end of the stabilization tube is fixed within the handle at a second attachment point that is spaced apart from the first attachment point and an elongated body and a distal end of the stabilization tube are not attached to the outer shaft component. A needle component of the apparatus is configured to be slidably disposed within the stabilization tube and removable therefrom, and the stabilization tube minimizes resistive forces exerted onto the needle component by the outer shaft component. |
