a device , system and methods for a minimally invasive bypass procedure , includes a graft having a supporting segment , an extending segment and a bypass segment . the supporting segment includes a flexible portion and a supporting member , and the extending segment includes a flexible portion and a supporting member . the extending segment has an initial configuration wherein it is unextended and a final configuration wherein it is extended proximally into the vessel . the bypass segment is positioned outside of the vessel to be treated , and the supporting segment is positioned within the vessel and distal to the incision . once the supporting segment and the supporting member are anchored in place , the extending segment is extended proximally past the incision site . thus , the supporting segment and the extending segment are substantially aligned , and allow for blood flow through the vessel while also providing blood flow around an obstruction via the bypass segment .
