Abstract

Methods and devices include making an incision at a single site of a patient. The single site located at an anterior of a chest or abdomen. The method also includes inserting a tunneling tool through the incision at the single site and preparing a first tunnel to a subcutaneous posterior location. A path of the first tunnel at least one of i) extends over a plurality of Intercostal gaps of the chest or ii) extends along and within one of the intercostal gaps. The method also includes positioning a first lead having an electrode within the first tunnel and preparing a second tunnel to a subcutaneous parasternal location along the chest. The method also includes positioning a second lead having an electrode within the second tunnel and positioning a pulse generator within a subcutaneous pocket and operatively coupling the first and second leads to the pulse generator.
