1. An endovascular system for deployment at branched arteries comprising: a main tubular graft deployable within a main artery comprising:
a proximal open end, an opposed open distal end and a circumferential sealing member disposed at a location near the proximal end, defining a proximal graft collar portion disposed between the proximal end of the graft and the circumferential sealing member; and
an anchoring member securably attached to the proximal graft collar portion, wherein at least a portion of the anchoring member is disposed beyond the proximal end of the main graft; and
a vent device deployable within a branch artery branched from the main artery comprising a main body having an open end and an opposed proximal end, the proximal end comprising a terminal open-cage, lattice structure having an atraumatic end radially extending across said proximal end and forming an apex;
wherein, in a deployed configuration of the system, the graft collar portion is configured to cover or occlude at least a portion of the branch artery, and
wherein, in the deployed configuration of the system, the apex of the atraumatic end of the open-cage, lattice structure pushes the graft collar away from a wall of the main artery to provide fluid communication for blood flow from the main artery through the vent device and into the branch artery, and
wherein the vent device is a discrete structure and separate from the main tubular graft.
