摘要:
A method and apparatus for introducing a cardiac lead to an implantation site that includes a catheter body having an outer wall and a distal leader and having a proximal portion extending from the first proximal end to a second distal end. An inner member is positioned within an outer lumen of the catheter body and is spaced from the outer wall to form a first inner lumen for receiving a guide tool inserted therein and a second lumen for receiving the cardiac lead while the guide tool is positioned within the first inner lumen. A distal end of the inner member forms 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.
