Abstract
A delivery catheter system for delivering a substance delivery member into a patient's left ventricle which includes a first delivery catheter with a shaped distal extremity configured to be aligned with or parallel to a longitudinal axis or long dimension of the patient's left ventricle and a second delivery catheter slidably and rotatably disposed within an inner lumen of the first delivery catheter which has a shaped distal shaft section and an inner lumen configured to slidably receive a substance delivery member such as an elongated cannula slidably disposed within a polymer sheath. The shaped distal section of the first delivery catheter is shaped or is shapeable within the patient's heart chamber. The second delivery catheter is advanced out of the inner lumen of the first delivery catheter until the distal end extends out of the port in the distal end of the first delivery catheter and provides a passageway for substance delivery member to engage the endocardial surface at a perpendicular or near perpendicular orientation.
