Abstract

The invention provides a septal occluder for closing a patent foramen ovale (PFO). The septal occluder includes a flexible central portion connecting two occlusion shells for the percutaneous transluminal treatment of an intracardiac defect. The septal occluder includes two occlusion shells connected by an elongate member capable of pivoting or articulating. The elongate member pivots or articulates at the juncture of the occlusion shell and the elongate member, according to one embodiment, or in the center of the elongate member, according to another embodiment. The elongate member can have one or more pivot points.

Claims

1. A septal occluder, comprising:

a first portion comprising a plurality of arms; and

a second portion comprising a plurality of arms;

wherein each of said arms comprises a free end and a pivot end, at least one of the arms comprises a pivot at said pivot end, and said arm comprising a pivot moves independently of the other arms.

2. The septal occluder of claim 1 wherein the pivot comprises a first loop connected to a second loop.

3. The septal occluder of claim 1 wherein the pivot comprises a ball and loop joint.

4. The septal occluder of claim 1 wherein the pivot comprises a ball and socket joint.

5. The septal occluder of claim 1 wherein the pivot comprises a pin and collar joint.

6. The septal occluder of claim 1 further comprising at least one centering coil spring.

7. A septal occluder, comprising:

a first body portion comprising a plurality of arms;

a second body portion comprising a plurality of arms;

a central body portion joining said first body portion and said second body portion and comprising at least one pivot, wherein said central body portion pivotably joins said first and said second body portions; and

wherein each of said arms comprises a free end and a pivot end, at least one of the arms comprises a pivot at said pivot end, and said arm comprising a pivot moves independently of the other arms.

8. The septal occluder of claim 7 wherein the central body portion pivot comprises at least a first loop connected to a second loop to form a pivotable joint.

9. The septal occluder of claim 8 wherein the first loop and the second loop further comprise a spring.

10. The septal occluder of claim 7 wherein the central body portion pivot comprises a ball and socket joint.

11. A septal occluder, comprising:

a first body portion comprising a plurality of arms;

a second body portion comprising a plurality of arms; and

a central body portion joining said first body portion and said second body portion wherein at least a portion of said central body portion comprises a coiled spring and said central body portion pivotably joins said first and said second body portions.

12. The septal occluder of claim 11 further comprising a hollow cylinder surrounding at least a portion of the central body portion.

13. A septal occluder, comprising:

a first body portion comprising a plurality of arms;

a second body portion comprising a plurality of arms; and

a central body portion joining said first body portion and said second body portion and comprising a ball and loop joint, wherein said central body portion pivotably joins said first and said second body portions.

14. A septal occluder, comprising:

a first body portion comprising a plurality of arms;

a second body portion comprising a plurality of arms; and

a central body portion joining said first body portion and said second body portion and comprising a knob and cylinder joint, wherein said cylinder comprises a lumen and a ridge and the knob contacts the ridge in the lumen of the cylinder, and said central body portion pivotably joins said first and said second body portions.

15. A septal occluder comprising:

a first body portion comprising a fixed end and a pivot end, said pivot end comprising a first socket;

a second body portion comprising a fixed end and a pivot end, said pivot end comprising a second socket; and

a central body portion comprising a first ball at a first end and a second ball at a second end, wherein said first socket is pivotably joined with said first ball to form a first pivot, and said second socket is pivotably joined with said second ball to form a second pivot; and

wherein said first pivot and said second pivot are oriented in different planes.

16. A septal occluder, comprising:

a first body portion;

a second body portion; and

a central body portion comprising a first elongate and a second elongate member, said first elongate member flexibly joining said first body portion and said second body portion, and said second elongate member extending circumferentially around at least a portion of the first elongate member.

17. The septal occluder of claim 16 wherein said second elongate member further comprises a stiffening member.

18. The septal occluder of claim 17 wherein said second elongate member further comprises a spring.
