Title: SYSTEMS AND METHODS FOR TRAVERSING A SITE OF OBSTRUCTION
Abstract:
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 tube having a passageway, the tube slidably disposed within the pathway of the push assembly and extending through a proximal end of the push assembly into the pathway of the push assembly to selectively move from a first position inside the push assembly to a second position outside the push assembly.
