Coronary sinus catheter
First Claim
1. A catheter for use in a coronary sinus comprising an elongated member containing a generally straight proximal section and a curved distal section, wherein the distal section continues in a first and second curve, wherein the first curve is a first longitudinal curve with a radius extending through an arc of about 30 to about 50 degrees, wherein the second curve is a second longitudinal curve extending through an arc with a radius of about 50 to about 70 degrees, wherein the second longitudinal curve is curved in substantially the same direction as the first longitudinal curve, and wherein the first and second longitudinal curves are substantially coplanar.
