Title: OCCLUSION SYSTEM FOR ANEURYSM REPAIR
Abstract:
An internal neck occlusion system treats an aneurysm (22) in a parent vessel (20). The parent vessel (20) defines a lumen (30). The aneurysm (22) includes a neck (26) and an inner wall defining a cavity (28) communicating with the lumen (30). The occlusion device (32) is configured for deployment within the cavity (28). The device (32) includes a collapsible member which is permeable to blood flow. The device (32) is arranged such that, when deployed within the cavity (28), the member bridges the neck (26) of the aneurysm (22) and is in contact with the inner wall. In treating the aneurysm (22), the device (32) is collapsed and endovascularly placed proximate the aneurysm (22). The device (32) is then expanded within the cavity so as to bridge the neck (26) of the aneurysm (22). An embolic agent (50) can be injected into the cavity (28) after the neck occlusion device is deployed.
