    Abstract: A catheter having a distal balloon and a deformable guidewire shaft of the catheter. The deformable guidewire shaft is adjacent to and external to the balloon. Inflation of the balloon bends the deformable guidewire shaft in order to orient or deflect a distal tip of the deformable guidewire shaft in a desired direction to guide and direct a guidewire extending through the deformable guidewire shaft towards a specific endovascular region. For example, it may be desired to orient the distal tip of the guidewire shaft towards a target vessel of a bifurcation or the balloon catheter may be used to bypass a Chronic Total Occlusion (CTO).

    Abstract: A catheter for use with a subintimal reentry guidewire includes a proximal portion having a proximal guidewire lumen and a proximal inflation lumen, a distal portion having a distal guidewire lumen and a distal inflation lumen, and an intermediate portion disposed between the proximal portion and the distal portion and having an intermediate inflation lumen in fluid communication with the proximal and distal inflation lumens. The intermediate portion is devoid of a guidewire lumen. A blocking mechanism disposed in the distal portion of the catheter is transformable from a non-blocking configuration in which a guidewire is free to translate through the distal guidewire lumen and a blocking configuration in which a guidewire disposed in the distal guidewire lumen is prevented from translating through the distal guidewire lumen.

    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.
