Abstract
A guiding introducer system for use in the left atrium comprised of an inner guiding introducer and an outer guiding introducer wherein the inner guiding introducer is comprised of a first and second section and the outer guiding introducer is comprised of a first and second sections. The guiding introducer system is for use in sensing, pacing, and ablating procedures within the left atrium of the human heart.
Claims8
A method for the mapping and/or ablation of anomalous conduction pathways within the left side of the heart comprising
- (a) introducing into the left side of the heart a guiding introducer system comprised of a precurved inner guiding introducer and a precurved outer guiding introducer, wherein each of the inner and outer guiding introducers contains a lumen passing therethrough, a proximal end and a distal end;
- (b) introducing the inner guiding introducer into the lumen of the outer guiding introducer and extending the distal end of said inner guiding introducer through the lumen of the outer guiding introducer;
- (c) introducing into the lumen of the inner guiding introducer a catheter for mapping and ablation of anomalous conduction pathways, wherein said catheter contains a distal tip and one or more electrodes;
- and
- (d) extending said distal tip of the catheter through the lumen of the inner guiding introducer and beyond the distal end of the inner and outer guiding introducers to allow the electrodes of the catheter to map and ablate one or more anomalous conduction pathways within the left side of the heart.
The method for the treatment of Wolfe-Parkinson-White syndrome within the left side of the heart comprising
- (a) introducing into the left side of the heart a guiding introducer system comprised of an inner and an outer guiding introducer, wherein each of the inner and outer guiding introducers contains a lumen passing therethrough, a proximal and a distal end;
- (b) introducing the inner guiding introducer into the lumen of the outer guiding introducer and extending the distal end of said inner guiding introducer through the lumen of the outer guiding introducer until the distal end of the inner guiding introducer is extended from the distal end of the outer guiding introducer;
- (c) introducing into the lumen of the inner guiding introducer a catheter, wherein said catheter contains a distal tip and one or more electrodes;
- and
- (d) extending said distal tip of the catheter through the lumen of the inner guiding introducer and beyond the distal end of the inner and outer guiding introducer to permit the electrodes of the catheter to ablate anomalous conduction pathways within the left side of the heart as a treatment for Wolfe-Parkinson-White syndrome.
