Abstract

Abstract A catheter for insertion in the ostium of the coronary sinus in the right atrium comprised of a main reinforced portion, an intermediate zone portion and a soft tip portion wherein a portion of the catheter is curved in a double curve, wherein the first curve is a first longitudinal curve, wherein the second curve is a second longitudinal curve, wherein the second longitudinal curve is curved in approximately the same direction as the first longitudinal curve and wherein the first and second longitudinal curves are generally coplanar.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 106 words
A catheter for insertion into the coronary sinus through the ostium of the coronary sinus via a superior approach, the catheter comprising: an elongated member comprising a generally straight proximal section, a curved distal section, and a tip portion at a distal end of the curved distal section; the curved distal section being sized and shaped to place the tip portion adjacent the ostium of the coronary sinus when the distal section is inserted into the right atrium through the superior vena cava; and the tip portion being in the shape of a hook sized and shaped for facilitating entry of the catheter into the ostium.
Claim 2
Dependent Claim 106 words
A catheter for insertion into the coronary sinus through the ostium of the coronary sinus via a superior approach, the catheter comprising: an elongated member comprising a generally straight proximal section, a curved distal section, and a tip portion at a distal end of the curved distal section; the curved distal section being sized and shaped to place the tip portion adjacent the ostium of the coronary sinus when the distal section is inserted into the right atrium through the superior vena cava; and the tip portion being in the shape of a hook sized and shaped for facilitating entry of the catheter into the ostium.
Claim 3
Dependent Claim 24 words
The catheter of claim 1, wherein the tip portion comprises a hook curve having a radius of curvature of less than about 2.0 cm.
Claim 4
Dependent Claim 20 words
The catheter of claim 2, wherein the hook curve has a radius of curvature of greater than about 0.5 cm.
Claim 5
Dependent Claim 18 words
The catheter of claim 2, wherein the hook curve extends through an arc greater than about 45 degrees.
Claim 6
Dependent Claim 18 words
The catheter of claim 4, wherein the hook curve extends through an arc less than about 90 degrees.
Claim 7
Dependent Claim 25 words
The catheter of claim 1, wherein the curved distal section comprises a first curve having a radius of curvature of less than about 11 cm.
Claim 8
Dependent Claim 25 words
The catheter of claim 1 or 6, wherein the curved distal section comprises a first curve extending through an arc greater than about 30 degrees.
Claim 9
Dependent Claim 18 words
The catheter of claim 7, wherein the first curve extends through an arc less than about 50 degrees.
Claim 10
Dependent Claim 34 words
The catheter of claim 1, wherein the curved distal section comprises a first curve and the tip portion comprises a hook curve, and the first and hook curves are curved in the same direction.
Claim 11
Dependent Claim 14 words
The catheter of claim 9, wherein the first and hook curves are substantially coplanar.
Claim 12
Dependent Claim 26 words
The catheter of claim 9 or 10, wherein the hook curve has a radius of curvature less than a radius of curvature of the first curve.
Claim 13
Dependent Claim 92 words
The catheter of claim 1, wherein the tip portion comprises a hook curve having a radius of curvature of less than about 2.0 cm.; wherein the hook curve extends through an arc greater than about 45 degrees; wherein the curved distal section comprises a first curve having a radius of curvature of less than about 11 cm; wherein the first curve extends through an arc greater than about 30 degrees; wherein the first and hook curves are curved in the same direction; and wherein the first and hook curves are substantially coplanar.
Claim 14
Dependent Claim 14 words
The catheter of claim 1 or 12, wherein the catheter has a fixed shape.
Claim 15
Dependent Claim 19 words
The catheter of claim 1 or 12, wherein the tip portion is more pliable than the curved distal section.
Claim 16
Dependent Claim 20 words
The catheter of claim 1, or 12, wherein the curved distal section is more pliable than the straight proximal section.
Claim 17
Dependent Claim 15 words
The catheter of claim 15 wherein the straight proximal section is reinforced with reinforcing material.
Claim 18
Dependent Claim 18 words
The catheter of claim 1 or 12, wherein at least one electrode is placed near the tip portion.
Claim 19
Dependent Claim 22 words
The catheter of claim 1 or 12, wherein the catheter comprises a lumen and at least one vent near the tip portion.
