Abstract
A blood flow disruption device for embolizing blood flowing into a vascular defect between a proximal vascular segment and a distal vascular segment, wherein the device includes a porous inner flow disruption element configured to extend through the defect between the proximal vascular segment and the distal vascular segment, whereby a first portion of the blood flowing into the inner flow disruption element from the proximal vascular segment is directed to flow into the defect and a second portion of the blood flowing into the inner flow disruption element is directed to flow into the distal vascular segment. A porous outer flow disruption element coaxially surrounds the inner flow disruption element and is radially expansible from a collapsed state to an expanded state. The outer flow disruption element, in its expanded state, promotes sufficient hemostasis of the first portion of the blood within the defect to embolize the defect.
