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.

Claims

1. A medical device comprising:

a first elongate body;

a second elongate body slidable disposed relative to the first elongate body;

a tubular body having a first end coupled to the first elongate body and a second end coupled to the second elongate body and expandable from an elongate profile to a radially expanded profile upon slidable movement of the first and second elongate bodies and the tubular body including a plurality of elongate slits or notches therealong forming a plurality of elongate struts wherein at least a portion of the plurality of struts includes a plurality of perforations; and

wherein the first and second elongate bodies are tubular and the second elongate body is slidably disposed in a lumen of the first elongate body.

2. The medical device of claim 1 wherein the slits or notches are angled so that the plurality of elongate struts are angled relative to the first and second elongate bodies.

3. The medical device of claim 1 wherein an entirety of the plurality of elongate struts includes a plurality of perforations.

4. The medical device of claim 1 wherein the first and second elongate bodies are rotatable relative to one another.
