Claim 1
Independent Claim
157 words
A process for ablating and mapping accessory pathways around the mitral valve of the left ventricle of the heart comprising (a) introducing into the left ventricle a guiding introducer system, comprising a precurved inner and a precurved outer guiding introducer, wherein each guiding introducer contains a lumen running lengthwise therethrough, a proximal and a distal end; (b) introducing the inner guiding introducer into the lumen of the outer guiding introducer; (c) introducing into the lumen of the inner guiding introducer an ablating and mapping catheter containing a proximal and a distal end, wherein said catheter has one or more electrodes located near the distal end of the catheter, (d) guiding the catheter to a selected location about the mitral valve of the heart on the ventricular side by use of the guiding introducer system, and (e) mapping and ablating the selected location about the mitral valve of the heart by use of the electrodes of the catheter.
