Methods and devices for endovascular embolization
First Claim
Patent Images
1. An endovascular occlusion device for occlusion of blood flow in a vessel, comprising:
- a support structure, self-expandable from a reduced cross section for transluminal navigation to an enlarged configuration for occluding a vessel;
the support structure defining a first axially outwardly facing concavity when in the enlarged configuration, the first axially outwardly facing concavity having an upstream opening and a downstream end;
a guidewire opening in the downstream end; and
a collapsible tube extending from the guidewire opening in an upstream direction into the first axially outwardly facing concavity.

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.
