Abstract
Methods and apparatus for treating vascular abnormalities in highly tortuous vessels are provided comprising a stent having at least one end region that engages a first portion of a circumference of a vessel in a region adjacent to an abnormality to anchor the stent, and a mid-region that engages a second portion of the circumference of the vessel wall to span the abnormality, the second portion having a smaller circumferential extent than the first portion. The mid-region includes a plurality of members that span the abnormality and form a lattice that occludes the abnormality. A delivery system also is provided to deliver the stent within a parent artery and orient the mid-region of the stent to span the abnormality.
