Abstract:
1. A vascular occlusion device for occluding a body cavity comprising: an elongate member including a proximal end and a distal end, embolization material being injected into the body cavity in a first direction through the distal end of the elongate member; and a deflecting device movable between a collapsed state and an expanded state, the deflecting device including a plurality of struts attached to the distal end of the elongated member and being expandable to contact an interior wall of the body cavity in the expanded state, the plurality of struts defining openings between adjacent ones of the struts; a tubular portion attached to the plurality of struts to cover the openings and configured to prevent the embolization material from flowing through the deflecting device when the deflecting device is in the expanded state and configured to be deflected by the embolization material such that the deflecting device is further movable from the expanded state to a deflected state by the embolization material when the embolization material flows in a second direction opposite to the first direction, wherein the elongate member includes an inner tubular member defining the occlusion lumen and an outer tubular member surrounding the inner tubular member, the inner tubular member extending distally from a distal end of the outer tubular member, each of the struts including a distal end pivotally attached to a distal end of the inner tubular member and a proximal end disposed proximally from the distal end of the inner tubular member and outside the outer tubular member, and wherein when the deflecting device is in the expanded state each of the proximal ends of the struts is moved away from the outer surface of the outer tubular member.
