Abstract
An introducer catheter used to deliver an endocardial cardiac electrode has a stylet lumen which collapses upon removal of the stylet to allow for more clearance for the lead and connector to pass when the catheter is removed after lead placement. The collapsible stylet lumen permits the introducer catheter size to be reduced to 8 or 9 French and provide for passage of a 4 French lead.
