Patent Images
1. An occlusion device comprising:
- a left side having a first set of arms;
a right side having a second set of arms, wherein the right side is spaced from and connected to the left side; and
a self centering mechanism which is laterally expandable to fill a defect, the mechanism comprising at least three rings located between the left and right sides wherein;
a first ring is connected to the left side;
a second ring is connected to the first ring; and
a third ring is connected to the second ring and to the right side.

Abstract
The present invention provides an occluder with a plurality of flexible rings that comprise a self centering mechanism to keep the occluder properly centered in a defect. The self centering mechanism is located between the left and right sides of the occluder. Because the occluder remains properly centered, the chance that portions of the aperture will be exposed is reduced and the effectiveness of the occluder is increased.
