Removable intracardiac RF device
First Claim
1. A medical device for occluding the tunnel of a patent foramen ovale (PFO) in a patient comprising:
- an occluding member, a sheath comprising a lumen;
an elongated member, one of said elongated member and said sheath axially moveable relative to the other; and
an energy delivering element comprising a plug comprising animal tissue and joined to said elongated member, wherein said plug comprises a core member sized and shaped to substantially fill the tunnel of the PFO, and wherein further the occluding member comprises a proximal occluder including a plurality of outwardly extending proximal arms supporting a proximal occlusion shell and a distal occluder including a plurality of outwardly extending distal arms supporting a distal occlusion shell and a centering mechanism secured between said proximal occluder and said distal occluder to center said proximal and said distal occluders about a defect, said centering mechanism comprising at least two centering members, each of said centering members secured between a separate one of said proximal arms and a corresponding one of said distal arms, at least one of said centering members comprising an elastomeric material.

Abstract
The present invention provides systems and methods for occluding or closing a patent foramen ovale of a patient (PFO). The invention includes a catheter carrying an energy delivery element. The catheter introduces the energy delivery element into the patent foramen ovale of a patient'"'"'s heart. Once appropriately positioned, the energy delivery element applies energy, such as radiofrequency energy, to the tissues surrounding the patent foramen ovale. The application of energy causes the tissues to join together, occluding the patent foramen ovale. The energy delivery element may be removable or permanently implanted in the patent foramen ovale.
