Abstract:
1. A method of collecting a medium from a coronary sinus using a catheter system, the method comprising the steps of: a) providing a catheter system including: b) positioning a distal end of the collection catheter within the patient's coronary sinus; c) detecting, with the injection sensor, a parameter of an injection of the medium into the injection catheter; d) establishing a start time of the injection; e) determining the volume of medium in the injection from the parameter of the injection; f) initiating operation of the aspiration unit at a predetermined time after the start time of the injection, wherein the step of initiating operation occurs only when the volume of medium determined in the injection is greater than a predetermined amount; and g) ceasing the operation of the aspiration unit after the initiating operation of the aspiration unit, wherein the step of ceasing the operation occurs a predetermined time after the injection sensor senses that the parameter of the injection is less than a predetermined amount.
