Claim:
1. An aneurysm therapy system, comprising, in combination: a catheter having a proximal end, a distal end, and a lumen extending between the proximal and distal ends, wherein the distal end of the catheter is configured to be positioned at or near an aneurysm; and an occlusive device, disposed within the lumen and configured to reside in the aneurysm to restrict fluid flow within the aneurysm, the occlusive device comprising: wherein the occlusive device is disposed within the catheter lumen such that the proximal section is proximal of the distal section along a longitudinal dimension of the occlusive device so that, during delivery of the occlusive device to the aneurysm, the distal section emerges from the distal end of the catheter before the proximal section, and wherein the proximal section is configured to expand to the expanded cross-sectional profile during advancement out of the distal end of the catheter, and the distal section is configured to distribute, along at least a portion of the coil length, a force of the advancement along an aneurysm interior wall.
