Abstract

An occlusion device comprises a first disk shaped portion made of shape memory material, and a second disk shaped portion made of shape memory material, the second disk shaped portion being connected to the first disk shaped portion, wherein at least one of the disk shaped portions has an edge portion that is arranged to have a bulbous profile.

Claims

1. An occlusion device comprising:

a first disk shaped portion made of shape memory material;

a second disk shaped portion made of shape memory material, the second disk shaped portion being connected to the first disk shaped portion;

wherein

at least one of the disk shaped portions has an edge portion that is arranged to have a bulbous profile.

2. An occlusion device as recited in claim 1, wherein the device is adapted to close a septal defect.

3. An occlusion device as recited in claim 1, wherein the bulbous profile approximately forms an arc having a central angle greater than 180°

.

4. An occlusion device as recited in claim 1, wherein:

the device is adapted to close a septal defect;

the disk shaped portion with the bulbous profile has a first side that is configured to be in direct contact with a patient'"'"'s septum, and a second side that is configured not to be in direct contact with the septum; and

the bulbous profile bulges in the direction of the second disk side.

5. An occlusion device as recited in claim 4, wherein the first side is substantially free from pressure points.

6. An occlusion device as recited in claim 1, comprising a first fastener configured to fasten the end of the first disk shaped potion and a second fastener configured to fasten the end of the second disk shaped portion, wherein at least one of the fasteners is placed within the interior of the device.

7. An occlusion device as recited in claim 1, further comprising a first fastener configured to fasten the end of the first disk potion and a second fastener configured to fasten the end of the second disk portion, wherein both the first and the second fasteners are placed within the interior of the device.

8. An occlusion device as recited in claim 1, further comprising a nonmetal patch attached to at least a portion of the occlusion device.

9. An occlusion device as recited in claim 1, wherein the first disk shaped portion and the second disk shaped portion are connected by a tension member.

10. An occlusion device as recited in claim 9, wherein the tension member includes a spring.
