Abstract

A septal occluder, such as one made from a polymer tube, can have portions on either side of a patent foramen ovale (PFO) or other septal defect. The portions on either side can be held in place with a catching mechanism that can take one of many forms. The tube can be made of bioresorbable materials.

Claims

1. A device for occluding a septal defect that has a distal side and a proximal side, the device comprising:

a distal end having a distal opening and a distal portion for contacting the distal side, the distal portion including a plurality of petals;

a proximal end having a proximal opening and a proximal portion for contacting the proximal side, the proximal portion including a plurality of petals;

a center portion for extending through the septal defect, and;

a coil extending through the proximal opening of the device and through the distal opening of the device such that portions of the coil extend distal of the distal end and proximal of the proximal end in a pre-deployed configuration and a deployed configuration.

2. The device of claim 1, wherein the device is adapted to close a patent foramen ovale (PFO).

3. The device of claim 1, wherein the coil being configured to maintain the proximal portion and the distal portion in the deployed configuration.

4. The device of claim 3, wherein the coil being configured to maintain the proximal portion and the distal portion in the deployed configuration in response to release from a delivery system.

5. The device of claim 4, wherein the portions of the coil extend distal of the distal end and proximal of the proximal end catch the distal end and the proximal end in response to release from the delivery system.

6. The device of claim 1, wherein the proximal portion and the distal portion each include a first area in the pre-deployed configuration and a second area in the deployed configuration, and the second area is less than the first area.
