1. A catheter system for positioning an intrapericardial electrical catheter against a site upon the surface of a mammalian heart, the mammalian heart having an inner surface and an outer surface defining a wall, the catheter system comprising:

  • a first tube, the first tube having a proximal end and a distal end, and defining a first lumen within the longitudinal axis of the first tube, an attaching means having a proximal end and a distal end, wherein the proximal end of the attaching means is affixed to the first tube at or near the distal end of the first tube and the distal end of the attaching means is adapted for attaching the first tube to the wall of the mammalian heart, a second tube, the second tube having a distal end adapted to puncture the wall of the mammalian organ and having a proximal end, wherein the second tube is adapted for placement within the first lumen, and an intrapericardial electrical catheter having a distal end and a proximal end, defining a second lumen within the longitudinal axis of the intrapericardial electrical catheter, wherein the intrapericardial electrical catheter is adapted for insertion through the first lumen, and wherein the distal end of the intrapericardial electrical catheter is shaped and adapted for placement against a site upon the surface of the mammalian heart.
