Occlusion device with centering arm
First Claim
1. An occlusion device having a proximal end and a distal end, the occlusion device comprising:
- a right center post located at the proximal end of the occlusion device, the right center post having distal and proximal ends;
a left center post located distally from the right center post, the left center post having distal and proximal ends;
a plurality of right arms attached to the right center post which collapse when the right center post is pulled proximally;
a plurality of left arms attached to the proximal end of the left center post; and
a plurality of centering arms emanating from the distal end of the left center post, each centering arm having an outer end portion which connects to an outer end portion of a right arm and wherein the plurality of centering arms define a flexible intermediate zone to center the occlusion device in an aperture.

Abstract
The present invention is an occlusion device having a centering arm network that self-centers across a defect and can be retrieved and redeployed in situ. A self centering system allows the center of the occlusion device to remain properly positioned within the defect, which increases the effectiveness of the occlusion device. The self centering system is comprised of a plurality of centering arms which define a flexible intermediate zone. In addition, the occlusion device of the present invention has a plurality of right arms connected to the plurality of centering arms which make it possible to retrieve and redeploy the occlusion device in situ.

18. An occlusion device having a proximal end and a distal end, the occlusion device comprising:
-
right and left floating center posts, the right center post being located at the proximal end of the occlusion device and the left center post being located distally from the right center post; a plurality of right arms attached to the right floating center post which collapse when the right center post is pulled in a proximal direction; a plurality of left arms attached to a proximal end of the left floating center post; a plurality of centering arms emanating from a distal end of the left floating center post, each centering arm having an outer end which connects to an outer end of a right arm wherein the plurality of centering arms extend through and center the occlusion device in an aperture; and a first sheet attached to the plurality of right arms which collapses when the right floating center post is pulled in a proximal direction. - View Dependent Claims (19, 20)
