Abstract
A steerable distal support system for accessing stenosis, partial occlusions, or complete occlusions within a body lumen. The steerable distal support system generally includes an elongate member that comprises a proximal portion, a more flexible intermediate portion and a deflectable distal tip. The deflectable distal tip is at a distal end of the elongate body to facilitate directionality and positioning of the steerable distal support system to the target site. Optionally, an expandable centering assembly may be disposed on the steerable support assembly to center and anchor the steerable support assembly within the body lumen.
