The invention is defined as a precurved coronary sinus guiding introducer for use in a cardiomyopathic heart comprising a flexible elongated member with a proximal and distal end. The elongated member comprises a generally straight, proximal portion and a precurved distal portion. In one embodiment the proximal portion and distal portion are formed to lie is a common plane. In another embodiment the portions are angulated with respect to each other in different planes. The precurved distal portion comprises at least one curved subportion and at least one curved or straight subportion. The precurved distal subportion curves through a generally circular arc away and is defined by a chord of predetermined length. The precurved distal subportion has a predetermined height above the chord. The curved or straight subportion is the distal section of the precurved distal portion.
