Abstract: A method and apparatus for reducing blood flow to an aneurysm proximate to a bifurcation having a source blood vessel a first branch vessel and a second branch vessel, the method comprising: providing a first mesh-like tube of bio-compatible material, the first mesh-like tube exhibiting a porosity index pre-selected to skew blood flow about the bifurcation away from the aneurysm; inserting the first mesh-like tube into the source blood vessel and the first branch vessel; and securing the first mesh-like tube to at least one of the source blood vessel and the first branch vessel, whereby blood flowing from the source blood vessel flows without undue impedance to the first branch vessel and the second branch vessel while being skewed away from the aneurysm.

Abstract: An implantable device for positioning in the vicinity of the bifurcation of the common carotid artery (CCA) into the internal carotid artery (ICA) and the external carotid artery (ECA), comprises a deflecting element suitable to deflect the flow of embolic material flowing in the CCS toward the ICA, into the ECA, without filtering.

Abstract: An implantable filtering device for implanting within an artery supplying blood to the brain, the device being made of bio-compatible material and comprising a filtering unit for entrapping plaque debris, and an anchoring member engageable with the walls of the carotid artery for anchoring said filtering unit at a fixed location with the artery. The filtering unit has a tapering shape extending between a wide inlet portion and a narrower outlet portion extending downstream, and a tap element fitted at the outlet portion for entrapping plaque debris.
