Method and apparatus for coronary sinus cannulation

摘要

A system and method of positioning an implantable medical device lead within a patient that includes introducing a distal tip of a first elongated member along a first location within the patient through a first introducing path, and introducing a distal tip of a second elongated member within the first location through a second introducing path. The distal tip of the first elongated member is engaged with the distal tip of the second elongated member at the first location, and, upon engagement, the distal tip of the first elongated member is advanced to a second location via the second elongated member as the second elongation member is advanced to the second location.
