Abstract
A delivery device can be provided with a low outer profile and high flexibility for navigating tortuous anatomy. An inner lumen defined by a shaft of the delivery device provides adequate space for delivery devices to target anatomy. Additionally, the delivery device maintains the patency of its lumen even when positioned within tortuous anatomy. The turns of filar(s) forming a coil of the shaft adjust their axial spacing relative to each other to avoiding buckling that would otherwise result in a narrowing of the inner lumen.
