Abstract
A flow directional infusion device includes a filter valve located at the distal end of a catheter. The filter valve constrains delivery of an embolic agent through the catheter to the locus of the aneurysm. In order to provide such delivery, the valve includes a longitudinal opening, radial opening or is otherwise partially permeable in a direction of the aneurysm so that the embolic agent or a delivery element for such agent is limited toward the aneurysm. In addition, the filter valve permits and directs blood flow within the blood vessel about the aneurysm during the treatment without obstructing the vessel and without allowing retrograde flow of the embolic agent in the vessel upstream of the aneurysm.
