REMOVABLE OCCLUSION SYSTEM FOR ANEURYSM NECK

摘要

A system for treating an aneurysm (26) in a vessel (28) includes a delivery device (10) having a delivery portion suitable for delivery of embolic material (44). The delivery device (10) is placed in a neck (40) of the aneurysm (36) and an expandable member (16) is placed proximate the neck (40). The expandable member (16) is expanded to overlie substantially the entire neck (40). Embolic material (44) is delivered to the aneurysm (36) with the delivery device. The expandable member (16) is held over the neck (40) to inhibit movement of the embolic material (44) out of the aneurysm (36). Blood is allowed to flow out of the aneurysm (36), past the neck (40) of the aneurysm (36), and through the vessel (28) while the expandable member (16) is held over the neck (40) of the aneurysm (36).
