1. An occlusion device comprising:
- an inner embolic element comprising a proximal section and a distal section, wherein the distal section has a first stiffness and the proximal section has a second stiffness that differs from the first stiffness; and
an expandable mesh capable of being transformed between a collapsed position and an expanded position,wherein the expandable mesh is disposed over a portion of the proximal section of the inner embolic element, andwherein the occlusion device is permanently deployed into an aneurysm.

Abstract
An occlusion device for treating an aneurysm can have an inner embolic device with a proximal section and a distal section. The distal section has a first stiffness and the proximal section has a second stiffness. Further, the device has an expandable mesh capable of a collapsed position and an expanded position. The mesh can be disposed over, and attached to, a portion of the proximal section of the inner embolic device. The first stiffness is greater than the second stiffness and the inner embolic device has a preselected shape which assists in transforming the expandable mesh from the collapsed position to the expanded position.
