1. A pacing lead for temporary atraumatic placement via transvascular access on an endocardial surface of a heart chamber of an animal body part to deliver an electrical signal comprising:
a. a lead manifold located outside the animal body; and
b. a pacing lead body connected to the lead manifold, the pacing lead body having a proximal end and a distal end, wherein the pacing lead body comprises a curled shaft having a distal end and a proximal end and a flexible shaped curved memory, wherein the curled shaft is located in the distal end of the pacing lead body for placement of the lead body against the surface of the body part, the curled shaft further including a plurality of cathode sites, which cathode sites are connected via electrical continuity such that at least one of the plurality of the cathode sites is adapted to be temporarily connected to the wall surface, wherein each of the plurality of cathode sites is connected to a specific cathode conduction wire for the cathode site and selected from a plurality of cathode conduction sires, wherein each of the plurality of cathode conduction wires extends along the pacing lead body to connect to an individual connector which is specific for the selected conduction wire on the lead manifold, wherein each of the plurality of cathode connectors is dimensioned and configured to be connected via a cathode connecting wire to a negative pole of a pulse generator, and wherein the pulse generator provides voltage and current to at least one of the plurality of cathode sites.
