Abstract

An implantable reservoir device (400) including an enclosed membrane (408) on an expandable frame (402) that defines a reservoir (410) and includes a porous region (418). The reservoir device (400) may be deployed and expanded within a blood vessel, and may be filled in situ or prefilled with a drug that passes through the porous region (418). Alternatively, a pair of expandable endovascular blockers (500) may be used to isolate a section of a blood vessel which may be filled with a drug that may be absorbed by the surrounding tissue.
