Coronary sinus catheter
First Claim
1. A catheter for use in the coronary sinus comprising an elongated member comprising a generally straight, proximal section, and a curved distal section, wherein the distal section comprises a first and second curve, wherein the first curve is curved through an overall arc of about 30 to about 50 degrees, wherein the second curve is curved through an overall arc of about 50 to about 70 degrees, and wherein the second curve is curved out of a plane formed by the first curve in an overall angle from about 30 to about 90 degrees.
