Steerable distal support system
First Claim
1. A steerable distal support system comprising:
- a hollow unibody elongate body comprising an integral proximal portion, intermediate portion, and a deflectable distal tip, wherein the proximal portion is stiffer than the intermediate portion;
a proximal housing coupled to the proximal portion of the elongate body; and
a pull wire that extends through an axial lumen of the elongate body from the proximal housing to the deflectable distal tip, wherein proximal actuation of the pull wire deflects the deflectable distal tip.

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.
