1. An occlusion device for occluding a body vessel, the occlusion device comprising:
- a first hub extending from a proximal end to a distal end along a longitudinal axis;
a second hub extending from a proximal part to a distal part, the second hub being disposed distally from the first hub along the longitudinal axis;
a first plurality of circumferentially spaced arcuate members extending between the first hub and the second hub, each circumferentially spaced arcuate member having a first end adjoining the distal end of the first hub and a second end adjoining the proximal part of the second hub, the members extending radially away from the longitudinal axis in an open configuration and extending substantially along the longitudinal axis in a closed configuration; and
a biocompatible material being disposed within a volume defined by the arcuate members between the distal end of the first hub and the proximal part of the second hub and forming an occlusive barrier that extends radially around the longitudinal axis, the longitudinal axis having a midpoint halfway between the distal end of the first hub and the proximal part of the second hub, the occlusive barrier extending through the volume defined by the arcuate members substantially at the midpoint of the longitudinal axis and lying in a plane that is substantially perpendicular to the longitudinal axis when deployed within the body vessel in the open configuration;
wherein the first and second ends of the circumferentially spaced arcuate members are substantially free of the biocompatible material.

Abstract
An occlusion device for occluding a body vessel including a first hub having a tubular wall defining a lumen having a longitudinal axis and a second hub disposed distally along the longitudinal axis. A plurality of arcuate members extend between the first hub and the second hub. The arcuate members extend radially away from the longitudinal axis in an open configuration and extend substantially along the longitudinal axis in a closed configuration. A biocompatible material is disposed within a volume defined by the arcuate members to form an occlusive barrier when deployed within the body vessel.
