Abstract: A flow diversion device for treating branch point aneurysms that includes a wire stent frame comprising a plurality of wire elements, the wire stent comprising a proximal limb and two distal limbs, wherein the proximal limb and the two distal limbs converge at a crotch of the wire stent frame. The plurality of wire elements may be braided together. The flow diversion device may have a substantially Y-shape or T-shape. The flow diversion device may be manufactured by using two tubular flow diversion devices to make a Y-shaped flow diversion device.
