Abstract
Abstract A guiding introducer system (fig.5) for use in the left atrium comprised of an inner guiding introducer (fig.3) and an outer guiding introducer wherein the inner guiding introducer is comprised of a first and second section and the outer guiding introducer (fig.4) 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
34 words
A guiding introducer system to be used in the left atrium of a human heart comprised of an inner guiding introducer and an outer guiding introducer wherein said guiding introducers are used in combination.
Claim 2
Dependent Claim
57 words
The guiding introducer system of Claim 1 wherein a transseptal dilator containing distal and proximal ends is used with the inner and outer guiding introducers, wherein said dilator curves at its distal end in a simple curve with a radius of about 3.0 to about 4.0 cm. with an arc of about 20 to about 40 degrees.
Claim 3
Dependent Claim
91 words
The guiding introducer system of Claims 1 or 2, wherein a 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 with a radius of about 0.5 to about 2.0 cm. to form an arc of approximately 150 to 270 degrees ending in the distal end of the second section of the inner guiding introducer.
Claim 4
Dependent Claim
133 words
The guiding introducer system of Claims 1 or 2, wherein the outer 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 comprised of a compound curved portion, curving upward in a curve with a radius of about 0.3 to about 0.7 cm. to form an arc of about 40 to about 60 degrees and at the same time curving to the right in a curve with a radius of about 0.8 cm. to about 1.2 cm. to form an arc of about 30 to 60 degrees, ending in the distal end of the second section of the outer guiding introducer.
Claim 5
Dependent Claim
32 words
The guiding introducer system of Claims 3 or 4, wherein a plurality of vents is provided near the distal end of the second section of the inner and/or the outer guiding introducer.
Claim 6
Dependent Claim
22 words
The guiding introducer system of Claims 3 or 4, wherein tip markers are contained within the inner and/or the outer guiding introducer.
Claim 7
Dependent Claim
30 words
The guiding introducer system of any one of Claims 1 to 6, for use with ablation catheters in the left side of the heart for the treatment of Wolfe-Parkinson-White Syndrome.
Claim 8
Independent Claim
189 words
A method for the mapping 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 an inner guiding introduce and an 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 of anomalous conduction pathways, wherein said catheter contains a distal tip and one or more electrodes; (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 one or more anomalous conduction pathways within the left side of the heart ; and (e) collecting the mapping data on a data carrier detached from the body.
Claim 9
Dependent Claim
93 words
The method of Claim 8 wherein the 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, wherein the second section is a curved section, curved with a radius of about 0.5 to about 2.0 cm. to form an arc of approximately 150 degrees to about 270 degrees ending in the distal end of the second section of the inner guiding introducer.
Claim 10
Dependent Claim
124 words
The method of Claim 8 wherein the outer 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 comprised of a compound curved section, curving upward with a radius of about 0.3 to about 0.7 cm. to form an arc of about 40 to about 60 degrees and at the same time curving to the right with a radius of about 0.8 cm. to about 1.2 cm. to form an arc of approximately 30 degrees to 60 degrees, ending in the distal end of the second end of the outer guiding introducer.
