Abstract: In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

Abstract: A vascular implant may comprise at least a first layer having one or more drawn fill tube wires (DFT wires) and at least a second layer having one or more non-DFT wires. The first layer may be braided from only a single DFT wire, and the second layer may be braided from a plurality of non-DFT wire. A vascular implant may also include a connecting wire composed of a shape memory alloy and that is shape set prior to connection to one or more implant layers composed of DFT wires.
