Abstract
Methods and devices for removing a thrombus are described. The device includes an expandable cylindrical structure made of wires and a self-expanding permeable shell located at the distal end of the cylindrical structure. Methods and devices for treating a cerebral aneurysm are described. The device may include a distal self-expanding resilient permeable shell, a proximal self-expanding resilient permeable shell, and an elongate support member positioned between the distal and proximal permeable shells. The elongate support member may be rigid or may be a coil, such as an extension spring. The distal and proximal permeable shells may be made from a plurality of braided filaments, the shells having different pore sizes. The device may also be a braided implant with a force biasing component, such as a coil or generally circular extension, attached to its distal end.
