Patent ID: 8535307

Claim:
A system for treating heart tissue to treat a cardiac arrhythmia, the system comprising: an energy transmission member for applying energy to the heart tissue in a pattern to treat the cardiac arrhythmia; a tissue securing member coupled with the energy transmission member for enhancing contact of the energy transmission member with the heart tissue; and a guiding member coupled with at least one of the energy transmission member and the tissue securing member for guiding the energy transmission member and the tissue securing member to a location for treating the heart tissue, wherein the tissue securing member is conformable to a surface topography of the heart tissue, wherein the energy transmission member comprises a unipolar radiofrequency energy transmission member, the unipolar radiofrequency energy transmission member comprising two linear portions continuous with a curved portion of the unipolar radiofrequency energy transmission member therebetween, and wherein the tissue securing member comprises a vacuum applying means.
