Abstract
The present invention is an occlusion device having a support hoop. The support hoop increases the ability of the occlusion device to form a seal around the defect and adds additional structural strength to the device by allowing distribution of pressure along a 360° continuum.
Claims30
An occlusion device for occluding a septal defect, the occlusion device comprising:
- a center post;
- a first occluding body connected to an end of the center post, wherein the first occluding body comprises:
- a continuous wire hoop at its outer edge;
- a set of arms connected between the center post and the hoop;
- and
- a first sheet attached to the continuous wire hoop and the set of arms, wherein the sheet comprises a reinforced edge forming a double layer of material which covers the hoop;
- a second occluding body connected to an opposite end of the center post, wherein the second occluding body comprises;
- a continuous wire hoop at its outer edge;
- a set of arms connected between the center post and the hoop;
- and
- a second sheet attached to the continuous wire hoop and the set of arms, wherein the sheet comprises a reinforced edge forming a double layer of material which covers the hoop.
