Claim:
1. A method of deploying an implantable device in proximity to the neck of an aneurysm of a human patient, the method comprising: navigating the implantable device to a location in proximity to the neck of the aneurysm in a low profile delivery arrangement; initiating deployment of the implantable device at the location in proximity to the neck of the aneurysm by advancing a distal portion of the implantable device incorporating lateral portions of a framework support structure and allowing the lateral portions to assume a larger diameter, deployed arrangement; positioning of the lateral portions of the framework support structure in close proximity to the neck of the aneurysm; continuing to deploy the implantable device by fully deploying the framework support structure in proximity to the neck of the aneurysm, wherein, in the fully deployed arrangement, the framework support structure positioned across the neck of the aneurysm has an inverted U-shape configured to arch over lumina of adjacent branch vessels, and wherein the inverted U-shaped framework support structure is configured to span unobtrusively over the lumina and without impeding flow in the vascular flow path; and completing deployment of the implantable device by deploying at least two proximal anchoring legs that, in the deployed arrangement, extend directly from the U-shaped framework support structure and into a neighboring vessel such that they are arranged substantially opposite one another and contact the walls of the neighboring vessel along opposed surface areas.
