Abstract
An introducer tool for a screw-in endocardial lead includes a plunger housing which is connected to the connector of the endocardial lead. The plunger housing is shiftable in a locking tube between retracted and advanced positions. A stylet is insertable through the plunger housing and through the lumen of the lead for shifting the helix assembly of the lead from a retracted to an advanced position. Clamping elements on the plunger housing engage the stylet to clamp the latter against movement when the plunger housing is in the advanced position. The lead may then be rotated relative to the introducer tool about the stylet to fix the helix assembly into the endocardium.
