1. An aneurysm embolization device, comprising:
a compressed configuration for intravascular delivery within an elongate shaft to a cerebral aneurysm and an expanded configuration for implantation in the aneurysm, wherein the device is configured to self-expand from the compressed configuration to the expanded configuration;
a body portion having a first end and a second end, the body portion being self-expandable to a first expanded configuration, wherein the body portion is configured to be positioned in the first expanded configuration such that at least some portions of the body portion engage a wall of the aneurysm;
an atraumatic tip portion extending from the first end of the body portion and being self-expandable to a second expanded configuration, different in shape or size from the first expanded configuration, wherein the tip portion is configured to be positioned at a dome portion of a wall of the aneurysm in the second expanded configuration to engage the dome portion; and
a base portion extending from the second end of the body portion and being self-expandable to a third expanded configuration, different in shape or size from the first expanded configuration, and wherein the base portion comprises a neck-engaging surface, wherein the base portion is configured to be positioned at a neck of an intracranial aneurysm in the third expanded configuration such that base portion extends across the neck and the neck-engaging surface engages against a neck portion of the aneurysm wall surrounding the neck.
