    Abstract: An occlusion bypassing apparatus is disclosed for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The apparatus includes an outer shaft component, an inner shaft component disposed within the outer shaft component, and a needle component slidably disposed within the inner shaft component. The inner shaft component includes a body portion and a needle housing, which is distal to the body portion. The needle housing is less flexible than the body portion. In order to smooth the transition between the body portion and the needle housing, the needle housing includes a transition portion that has a variable flexibility along its length that decreases in a distal direction. A curved distal end of the needle component is distally advanced relative to the inner shaft component to pierce through the intima of the vessel and thereafter enter the true lumen.

    Abstract: A catheter for subintimally bypassing an occlusion in a vessel includes a catheter shaft including a guidewire lumen disposed therethrough and having a shaft longitudinal axis, at least two balloons coupled to an exterior of the catheter shaft such that longitudinal axes of the balloons are in a common plane with the shaft longitudinal axis when uninflated and with no external forces on the catheter. The balloons are configured such that when the catheter is disposed in the subintima of a vessel and the balloons are inflated, a tip of the catheter shaft is oriented towards a true lumen of the vessel distal of the occlusion.

    Abstract: An apparatus having a distal end that may be selectively bent in situ. The apparatus has a curved configuration and a substantially straightened configuration. First and second tubular components of the apparatus each include a distal portion that is at an acute angle with respect to a longitudinal axis of the apparatus. The second tubular component is rotatably disposed within the first tubular component. In the curved configuration, the distal portions of the first and second tubular components are positioned to extend at substantially the same acute angle with respect to the longitudinal axis of the apparatus. In the substantially straightened configuration, the distal portions of the first and second tubular components are positioned such that the curvatures thereof counterbalance each other. The first and second tubular components may be used in an occlusion bypassing apparatus for re-entering the true lumen of a vessel after subintimally bypassing an occlusion.
