1. A device for treatment of a vascular defect, comprising:
a self-expanding permeable shell having a proximal end, a distal end, and a longitudinal axis; the shell comprising a mesh, wherein the permeable shell has a radially constrained elongated shape configured for delivery within a microcatheter and has an expanded shape with an axially shortened configuration relative to the radially constrained state;
the expanded shape of the permeable shell forming a first plurality of circumferentially-arrayed lobes and a second plurality of circumferentially-arrayed lobes, and,
a circumferentially-extending channel located between the first plurality of circumferentially-arrayed lobes and the second plurality of circumferentially-arrayed lobes;
wherein the circumferentially-extending channel, the first plurality of circumferentially-arrayed lobes, and the second plurality of circumferentially-arrayed lobes are each formed from a plurality of elongated resilient filaments of the mesh;
wherein the mesh has a memorized shape which self-expands to form the circumferentially-extending channel, the first plurality of circumferentially-arrayed lobes, and the second plurality of circumferentially-arrayed lobes;
wherein the first plurality of circumferentially-arrayed lobes extend between the proximal end of the shell and the circumferentially-extending channel; and,
wherein the second plurality of circumferentially-arrayed lobes extend between the distal end of the shell and the circumferentially-extending channel.
