1. A device for treatment of an aneurysm within a patient's vasculature, comprising:
a self-expanding resilient permeable shell having a proximal end, a distal end, a distal hub, and a longitudinal axis, the shell comprising a plurality of elongate resilient filaments having a braided structure, wherein the plurality of filaments are secured by the distal hub, wherein a distal region of at least some of the plurality of filaments that extend in a generally radial direction beyond the distal hub of the permeability shell is unraveled and straight and form an extension having a generally circular shape configured to atraumatically track around a diameter of the aneurysm when expanded, wherein a distal end of each of the at least some of the plurality of filaments that extend beyond the distal hub define a perimeter of the generally circular shape, and wherein, when expanded, a substantial length of a distal end region of each of the at least some of the plurality of filaments has longitudinal axis generally perpendicular to the longitudinal axis of the permeable shell;
wherein the permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with a globular, axially shortened configuration relative to the radially constrained state, the permeable shell having a plurality of openings formed between the braided filaments.
