Removable occlusion system for aneurysm neck
First Claim
1. A medical device comprising:
- a first elongate tubular body;
a second elongate tubular body slidably disposed in a lumen of the first elongate tubular body; and
a shield formed of a plurality of non-woven elongate struts and the plurality of elongate struts having a first end coupled to the first elongate tubular body and a second end coupled to the second elongate tubular body and expandable from an elongate profile to a radially expanded profile upon slidable movement of the second elongate tubular body relative to the first elongate tubular body.

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