Abstract
Abstract A process for the mapping and/or ablation of accessory pathways around the mitral valve using a retrograde approach by use of ablation and/or mapping catheters guided by precurved guiding introducers. Also disclosed are shapes for the guiding introducers to be used for the ablation and/or mapping of the accessory pathways around the mitral valve using a retrograde approach.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
39 words
A guiding introducer for use with an ablation catheter for the ablation and/or mapping of accessory pathways around the mitral valve of the left ventricle of the heart from the ventricle side comprising shaped first, second and third sections.
Claim 2
Dependent Claim
42 words
The guiding introducer of Claim 1 wherein the first section is a generally elongated hollow straight catheter section of sufficient length for introduction into the patient and for manipulation from the point of insertion through to a desired location within the heart.
Claim 3
Dependent Claim
85 words
The guiding introducer of Claims 1 or 2 wherein the second section is a curved section comprised of a smooth flat curve with a radius of about 1.0 in. to about 2.0 in., wherein the arc of the curve is from about 160 to about 200 degrees, and wherein preferably the radius of the curved section of the second section is from about 1.3 in. to about 1.7 in., wherein the arc of the curve is from about 170 to about 190 degrees of arc.
Claim 4
Dependent Claim
99 words
The guiding introducer of any one of Claims 1 to 3 wherein the third section is comprised of a straight portion and a curved portion, and wherein preferably the straight portion is from about 2.0 to about 3.5 in. in length and the curved portion comprises a curve with a radius of about 0.5 to about 1.5 in. with an arc of about 70 to about 110 degrees, wherein the curve is within about 45 degrees of being in a plane formed by the first and second sections, and wherein the curved portion curves generally toward the first section.
Claim 5
Dependent Claim
73 words
The guiding introducer of any one of Claims 1 to 4 wherein the straight portion is from about 2.0 to about 3.5 in. in length and the curved portion comprises a curve with a radius of about 0.5 to about 1.5 in., with an arc of about 70 to about 110 degrees, wherein the curve is within about 45 to about 60 degrees of a plane formed by the first and second sections.
Claim 6
Dependent Claim
73 words
The guiding introducer of any one of Claims 1 to 5 wherein the straight portion is from about 2.0 to about 3.5 in. in length and the curved portion comprises a curve with a radius of about 0.5 to about 1.5 in. with an arc of about 70 to about 110 degrees, wherein the curve is within about 60 to about 115 degrees of a plane formed by the first and second sections.
Claim 7
Dependent Claim
73 words
The guiding introducer of any one of Claims 1 to 6 wherein the straight portion is from about 2.0 to about 3.5 in. in length and the curved portion comprises a curve with a radius of about 0.5 to about 1.5 in. with an arc of about 70 to about 110 degrees, wherein the curve is within about 115 to about 155 degrees of a plane formed by the first and second sections.
Claim 8
Dependent Claim
73 words
The guiding introducer of any one of Claims 1 to 7 wherein the straight portion is from about 2.0 to about 3.5 in. in length and the curved portion comprises a curve with a radius of about 0.5 to about 1.5 in. with an arc of about 70 to about 110 degrees, wherein the curve is within about 155 to about 180 degrees of a plane formed by the first and second sections.
Claim 9
Dependent Claim
44 words
The guiding introducer of any one of Claims 1 to 8 wherein the ablating utilizes one of the following sources of energy: direct current, high energy direct current, low energy direct current or fulgutronization procedures, and microwave, ultrasound, laser procedures and radio frequency procedures.
Claim 10
Dependent Claim
33 words
The use of the guiding introducer of any one of Claims 1 to 9 for the ablation and/or mapping of accessory pathways around the mitral valve of the left ventricle of the heart.
