Systems for providing access across a site of obstruction and methods for manufacturing and using such systems are provided. Such systems may include a cannula having a lumen, an everting member coupled to the cannula, and a push assembly having a pathway. The push assembly may be slidably disposed within the lumen of the cannula and connected to a proximal end of the everting member to move the everting member from an inverted position inside the cannula to an everted position outside the cannula. The systems may also include a hard tube having a passageway, the hard tube slidably disposed on or within the pathway of the push assembly. The hard tube being designed to create and opening within and traverse and obstruction within a structure.
