Abstract

An introducer sheath comprising a curved shape that follows the right sided vasculature when introduced through the right side subclavian vein and which stops far short of the coronary ostium in the right atrium. No attempt is made to access the coronary sinus through the sheath. The sheath establishes a fulcrum point on the upper lateral wall of the superior vena cava and comprises the ability to be removed from the implanted pacemaker lead without flipping the distal end of the sheath to cause a pull back of the pacemaker lead. The more proximal portions of the sheath extend through the superior vena cava and provide a force which biases the sheath against the lateral wall of the lower portion of the superior vena cava to establish a fulcrum or pivot point which positions the distal end of sheath at the desired location.
