Balloon catheter for abrading a patent foramen ovale and method of using the balloon catheter
First Claim
1. A balloon catheter device for abrading a patent foramen ovale comprising:
- A a sheath catheter with proximal and distal ends;
B a foramen ovale balloon catheter deployably retained within the sheath catheter, the foramen ovale catheter having proximal and distal ends;
C an inflatable balloon attached near the distal end of the foramen ovale balloon catheter;
D a plurality of abrasive members attached over the inflatable balloon.

Abstract
The present invention provides a device and method for closing a patent foramen ovale. The present invention comprises a catheter sheath with proximal and distal ends. A balloon catheter with a plurality of abrasive members is deployably retained within the catheter sheath. Once the catheter sheath is placed by a treating health care professional across a patent foramen ovale, the balloon catheter is advanced such that the balloon and the abrasive members are deployed outside of the distal end of the catheter sheath. The catheter sheath is then removed from the foramen ovale and the balloon is inflated. The treating healthcare professional then abrades the inner surfaces of the patent foramen ovale to thereby cause an area of thrombogenesis. The balloon catheter is then deflated and the abrasive members are then repositioned into the distal end of the catheter sheath and then removed from the patient. The thrombogenic area created along the inner surfaces of the patent foramen ovale then creates of thrombus which over time turns into a scar and the foramen ovale is obliterated.
