| 66. A precurved coronary sinus guiding introducer with a distal end for use in a dilated cardiomyopathic heart comprising:
a flexible elongated member with a proximal and distal end, wherein the elongated member comprises
a proximal portion biased to be generally straight and which assumes a general direction, and
a precurved distal portion biased to curve through an arc defined by a chord of predetermined length and wherein the precurved
distal portion has a predetermined height above the chord, the chord of the precurved distal portion has a length measured
on a perpendicular to a longitudinal axis of the proximal portion between the beginning of the precurved distal portion where
it meets the longitudinal axis of the proximal portion and a longitudinal axis of the opposing end of the precurved distal
portion drawn parallel to the longitudinal axis of the proximal portion, and wherein the chord has the predetermined length
of approximately 3.5 to 7 inches, the predetermined height above the chord is approximately 1.5 inches to 4.0 inches such
that the distal end of the introducer is oriented to extend in a direction approximating the general direction of the proximal
portion and readily accesses the coronary sinus ostium in the dilated cardiomyopathic heart.
