1. A delivery system for delivering an implantable medical lead to an implantation site on a pericardium of a patient heart, the implantable medical lead including a helical tip electrode disposed on a distal end of the medical lead, the delivery system comprising:
a delivery catheter having a proximal catheter end and a distal catheter end opposite the proximal catheter end, the delivery catheter defining an inner lumen, the delivery catheter configured to be advanced to the implantation site on the pericardium;
a lead receiving sheath within and extending along the inner lumen, the lead receiving sheath having a proximal sheath end and a distal sheath end opposite the proximal sheath end, the distal sheath end configured to be located at the implantation site on the pericardium; and
a fixation tine extending from one of the distal catheter end and the distal sheath end, the fixation tine located relative to the distal sheath end and shaped to engage the pericardium to dispose the distal sheath end adjacent to the implantation site.
