Abstract

The invention relates to a medical device and a method of using it. The device is a stent which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The stent is configured to have a central portion defined by “open” cells and at least two end portions, defined by “closed” cells, spaced apart and directly connected to the distal and proximal ends of the central portion of the stent. The stent may also optionally have a covering or a lattice with openings.
