The invention describes an arbitration management method and system for use in identifying RFID transponders or tags which each transmit a response signal to a reader within a respective waiting period the maximum duration of which can be adjusted. A first solenoid valve is in electrical communication with the activate switch and a second solenoid valve is in electrical communication with the deactivate switch. The lead includes at least one sensor located within the coronary vein configured to generate a signal indicative of at least one dimensional parameter of the coronary vein. A rear of the base portion is concaved forward to form a first receiving cavity, and further concaved forward to form an extending cavity. The dryings can be carried out at ambient temperature.
