Catheter with vessel lining and methods for using same

摘要

A system for providing access across a site of obstruction is provided. The system may include a sleeve, having a distal portion that can move from an inverted position to an everted position. A balloon situated within the sleeve can be extended so as to evert sleeve. A pathway can extend across a juncture between the distal portion and the remaining portion of the sleeve so as to provide access across the site of obstruction. A method for providing access across the site of obstruction is also provided.

主权项

1. A system for providing access across a site of obstruction, the system comprising:
a sleeve having an inflation lumen; an anchoring member coupled to the sleeve, the anchoring member being in fluid communication with the inflation lumen and being expandable from a deflated position to an inflated position to anchor the sleeve near a site of obstruction when the inflation lumen is pressurized to an anchoring pressure sufficient to anchor the sleeve in proximity to a site of obstruction; and an everting member movable from an inverted position inside the sleeve to an everted position outside the sleeve due to a pressure increase in the inflation lumen greater than the anchoring pressure, wherein the sleeve comprises a distal portion configured to be moved by the everting member from an inverted position inside the sleeve to an everted position outside the sleeve.
