    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.

    Abstract: Catheter assemblies include a stabilization mechanism disposed at a distal end of the catheter assembly for stabilizing the catheter assembly within a subintimal space. The stabilization mechanism includes a self-expanding support structure that is slidably positionable within an inflatable balloon. The catheter assemblies include an outer shaft which has the balloon at a distal end thereof and an inner shaft which has the support structure mounted on a distal end thereof. The inner shaft is slidably disposed within a lumen of the outer shaft and has a first configuration in which the support structure is held in a compressed state within the outer shaft and a second configuration in which the support structure is permitted to return to an expanded state within the inflatable balloon. In the expanded state, the stabilization mechanism has a flattened laterally-extending profile.

    Abstract: Occlusion bypassing apparatuses are disclosed for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The occlusion bypassing apparatuses include a shaft component and a needle component slidably disposed within the shaft component and having an angled configuration when deployed. In embodiments hereof, the needle component has an angled distal tip segment that may be utilized to selectively bend a flexible distal portion of the shaft component in order to extend the flexible distal portion towards the true lumen of the vessel. The needle component is distally advanced relative to the shaft component to pierce through the intima of the vessel and thereafter enter the true lumen.

    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.
