EP Technologies, Ryan Maki Mann & Hohenfeldt, November 19, 1996: US05575810 (340 worldwide citation)

A method of ablating tissue in the heart to treat atrial fibrillation introduces into a selected atrium an energy emitting element. The method exposes the element to a region of the atrial wall and applies ablating energy to the element to thermally destroy tissue. The method forms a convoluted lesi ...
