Abstract

An aneurysm therapy system is provided that can include a catheter and an occlusive device. The catheter can have a lumen extending between proximal and distal ends thereof. The occlusive device can be disposed within the catheter lumen and configured to reside in the aneurysm to restrict fluid flow within the aneurysm. The device can have a distal section that includes a coil having an outer diameter, a coil length, and a coil flexibility. The device can also include a self-expanding braided proximal section. The braided proximal section can be configured to expand during advancement out of the distal end of the catheter, and the distal section can be configured to distribute, along at least a portion of the coil length, a force of the advancement along an aneurysm interior wall.
