Abstract
A coronary sinus catheter having a flexible elongate member with proximal and distal extremities. The flexible elongate member has at least two lumens extending longitudinally thereof. A balloon is mounted on the distal extremity of the flexible elongate member and has its interior in communication with one of the lumens. The balloon has at least one truncated conical surface with outwardly facing spaced apart parallel concentric lands formed thereon for frictionally engaging the coronary sinus to provide a high retentive force for the catheter.
