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).
