    Abstract: True lumen reentry devices and methods useable for redirecting a guidewire from a subintimal tract within a wall of a blood vessel into the true lumen of the blood vessel. A reentry catheter device comprises a main catheter shaft having at least one guidewire outlet aperture with at least one side tube located on a distal portion of the main catheter shaft. The side tube(s) is/are tracked over initially inserted guidewire(s) to advance a distal portion of the reentry catheter device into the subintimal tract with a guidewire.

    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: 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: 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.
