1. A guide catheter for introducing a cardiac lead having a distal fixation mechanism through a pathway from an incision to an implantation site, comprising:

  • an elongated catheter body extending between a first proximal end and a first distal end, the catheter body including an outer wall and a distal leader and having a proximal portion extending from the first proximal end to a second distal end, the distal leader extending distally from the second distal end, and the outer wall extending along the proximal portion and the distal leader and forming an outer lumen extending through the proximal portion and the distal leader; and

    an inner member positioned within the outer lumen and having a third distal end, the inner wall spaced from the outer wall to form a first inner lumen for receiving a guide tool inserted therein to aid in steering the catheter body through the pathway and a second lumen for receiving the cardiac lead while the guide tool is positioned within the first inner lumen, the third distal end forming a first opening at a distal end of the first inner lumen and a second opening at a distal end of the second inner lumen, the first opening and the second opening positioned proximal the distal leader.
