Methods and devices for endovascular embolization
First Claim
Patent Images
1. A method of occluding a vessel, comprising the steps of:
- advancing an occlusion device over a guidewire, the occlusion device comprising a collapsible tube having a guidewire lumen;
deploying an anchoring lobe of the occlusion device in a vessel, without total vessel occlusion;
thereafter deploying an occlusion lobe of the device in the vessel to occlude blood flow;
wherein the anchoring lobe is separated from the occlusion lobe by a hub, the anchoring lobe being downstream of the occlusion lobe; and
retracting the guidewire to allow the collapsible tube to collapse in the occlusion lobe in response to blood pressure, the collapsed tube extending from the hub and into the occlusion lobe.

Abstract
The present disclosure describes an occlusion device and methods of delivering the occlusion device. The occlusion device can include an expandable structure configured to move between an unexpanded configuration and an expanded configuration. The expandable structure can be configured to have an expansion ratio of at least about 5:1. Further, the occlusion device can be configured to prevent substantially all fluid from flowing past the occlusion device when the occlusion device is in the expanded configuration in the vessel.
