If the flap does not seal, it is called a patent foramen ovale.

The closure apparatus and methods may be used to close a patent foramen ovale (PFO).

When the opening does not close, it is called a patent foramen ovale.

The traumatized area created along the inner surfaces of the patent foramen ovale heals over time, and turns into a scar obliterating the foramen ovale.

When the foramen ovale doesn't close, it's called a Patent Foramen Ovale.

The devices are deployed at the foramen ovale to secure the septum secundum and septum primum together, thus sealing the foramen ovale.

When the foramen ovale doesn't close, it's called a patent foramen ovale.

When the foramen ovale doesn’t close, it’s called a Patent Foramen Ovale.

When the foramen ovale doesn’t close, it’s called a patent foramen ovale.

If it dose not close it is called a patent foramen ovale.

The devices and techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube.

A closure device for a patent foramen ovale (PFO) has proximal and distal occlusion members for applying compressive forces to tissue on opposite sides of septal defects to help close the defects.

Additional aspects of the invention relate to shape, formation, positioning, and detachment of the closure device about the internal tissue opening.

The catheter sheath (11) is then removed from the foramen ovale, and the balloon is inflated.

The device (200, 300) is deployed at the foramen ovale (402) to secure the septum primum (444) and septum secundum (442) together, thus sealing the foramen ovale.
