Abstract
Abstract A guiding introducer system for use in the right 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, second and third section. The guiding introducer system is for use in sensing, pacing, and ablating procedures within the right atrium of the human heart.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A method for the mapping and ablation of anomalous conduction pathways within the right side of the heart comprising (a) introducing into the right side of the heart a precurved, guiding introducer system comprised of a precurved, inner guiding introducer and a precurved, outer guiding introducer, wherein each of the precurved, inner and outer guiding introducers contains a lumen passing therethrough, a proximal end and a distal end, and wherein the precurved, inner guiding introducer is contained within the lumen of the precurved, outer guiding introducer as they are simultaneously inserted into the body; (b) introducing into the lumen of the precurved, 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 (c) extending said distal tip of the catheter through the lumen of the precurved, inner guiding introducer and beyond the distal end of the precurved, inner and outer guiding introducers to allow the electrodes of the catheter to map and ablate one or more anomalous conduction pathways within the right side of the heart.
Claim 2
Independent Claim
182 words
A method for the mapping and ablation of anomalous conduction pathways within the right side of the heart comprising (a) introducing into the right side of the heart a precurved, guiding introducer system comprised of a precurved, inner guiding introducer and a precurved, outer guiding introducer, wherein each of the precurved, inner and outer guiding introducers contains a lumen passing therethrough, a proximal end and a distal end, and wherein the precurved, inner guiding introducer is contained within the lumen of the precurved, outer guiding introducer as they are simultaneously inserted into the body; (b) introducing into the lumen of the precurved, 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 (c) extending said distal tip of the catheter through the lumen of the precurved, inner guiding introducer and beyond the distal end of the precurved, inner and outer guiding introducers to allow the electrodes of the catheter to map and ablate one or more anomalous conduction pathways within the right side of the heart.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein the ablation procedure utilizes an energy source chosen from radio frequency, thermal, laser or direct current (high energy, low energy or fulgutronization procedures).
Claim 4
Dependent Claim
16 words
The method of claim 2 wherein the energy source used for ablation is radio frequency energy.
Claim 5
Dependent Claim
91 words
The method of claim 1 wherein the precurved, inner guiding introducer is comprised of a first and second sections each with proximal and distal ends, wherein the first section is a generally elongated straight section, wherein merged with the distal end of said first section is the second section which is a curved section curved with a radius of about 0.5 in. to about 1.5 in. to form an arc of approximately 150 to 270 degrees, ending in the distal end of the second section of the precurved, inner guiding introducer.
Claim 6
Dependent Claim
154 words
The method of claim 1 wherein the precurved, outer guiding introducer is comprised of first, second and third sections, each with proximal and distal ends, wherein the first section is a generally elongated straight section, wherein merged with the distal end of said first section is the second section which is comprised of a curved portion and a straight portion, wherein the curved portion has a radius of about 0.4 in. to about 0.6 in. to form an arc of approximately 40 to about 60 degrees, wherein the straight section is from about 0.4 to about 0.7 in. in length, wherein merged with the distal end of the second section is the third section, which is comprised of a curved portion with a radius of about 0.75 to about 1.25 in. to form an arc of approximately 30 to about 60 degrees and wherein the third section is generally coplanar with the second section.
Claim 7
Independent Claim
167 words
A method for the treatment of Wolff-Parkinson-White syndrome within the right side of the heart comprising (a) introducing into the right side of the heart a precurved, guiding introducer system comprised of a precurved, inner guiding introducer and a precurved, outer guiding introducer wherein each of the precurved, inner and outer guiding introducers contains a lumen passing therethrough, a proximal and a distal end, and wherein the precurved, inner guiding introducer is contained within the lumen of the precurved, outer guiding introducer as they are simultaneously inserted into the body; (b) introducing into the lumen of the precurved, inner guiding introducer a catheter, wherein said catheter has one or more electrodes; and (c) extending said distal tip of the catheter through the lumen of the precurved, inner guiding introducer and beyond the distal end of the precurved, inner and outer guiding introducers to permit the electrodes of the catheter to ablate anomalous conduction pathways within the right side of the heart as a treatment for Wolff-Parkinson-White syndrome.
Claim 8
Independent Claim
167 words
A method for the treatment of Wolff-Parkinson-White syndrome within the right side of the heart comprising (a) introducing into the right side of the heart a precurved, guiding introducer system comprised of a precurved, inner guiding introducer and a precurved, outer guiding introducer wherein each of the precurved, inner and outer guiding introducers contains a lumen passing therethrough, a proximal and a distal end, and wherein the precurved, inner guiding introducer is contained within the lumen of the precurved, outer guiding introducer as they are simultaneously inserted into the body; (b) introducing into the lumen of the precurved, inner guiding introducer a catheter, wherein said catheter has one or more electrodes; and (c) extending said distal tip of the catheter through the lumen of the precurved, inner guiding introducer and beyond the distal end of the precurved, inner and outer guiding introducers to permit the electrodes of the catheter to ablate anomalous conduction pathways within the right side of the heart as a treatment for Wolff-Parkinson-White syndrome.
Claim 9
Dependent Claim
