Claim Text:
1. A method of treating an aneurysm at a junction of a bifurcation having an afferent vessel and efferent vessels, the aneurysm having a neck and a fundus, the method comprising: advancing a catheter proximate to the junction of the bifurcation, the catheter at least partially containing a device in a compressed state, the device comprising a proximal end, a distal end, and a middle region between the proximal end and the distal end, the middle region consisting of a plurality of filaments extending from the proximal end to the distal end, the plurality of filaments being coupled at and only at both the proximal end and the distal end; deploying the device from at least partially inside the catheter to outside the catheter with a distal portion of the device at the junction of the bifurcation abutting the neck and a proximal portion expanded against walls of the afferent vessel, the distal portion having a distal cross-sectional dimension greater than a proximal cross-sectional dimension of the proximal portion, wherein, during deployment, the device self-expands to conform in an expanded state to the junction of the bifurcation, and wherein, after deployment and while the proximal end of the device is connected to the catheter, the device acts as a scaffolding to inhibit herniation of objects out of the neck of the aneurysm and permits perfusion of fluid to the efferent vessels, wherein the distal portion of the device comprises a distal section, the plurality of filaments spiraling towards the distal end in the distal section; and withdrawing the catheter.
