US Patent 7966076 Lead and apparatus for stimulation of the cardiac plexus

A medical electrical lead adapted to stimulate a patient's cardiac plexus includes a flexible distal portion having a surface adapted to conform to an outer surface of an aortic region generally associated with the cardiac plexus. The distal portion can have one or more elongate members. Alternatively, the distal portion can have a generally planar portion. The distal portion is flexible such that it can be furled or otherwise compacted such that it can be delivered to a target stimulation site using a guide catheter or other delivery tool, such as a cannula.
