<p>A guiding introducer (10) containing openings (16) is used with an ablation catheter (18) of cardiac tissue. The introducer comprises a first proximal section (12), generally elongated and hollow, and a second distal section (14), lumened with a plurality of openings (16). The openings (16) have a sufficient size to permit ablation of cardiac tissue through them by an electrode (20) of the ablation catheter (18).</p> |
