Abstract
A remote sensing catheter system including an injection catheter and a collection catheter. In one method of use, an external sensor of the system determines the timing of operation of the collection catheter. In another method of use, a sensor determines the volume of medium in the injection.

25. A system for removing a medium from a patient'"'"'s coronary sinus, the system comprising:
-
a) a collection catheter and a collection sensor; b) an aspiration unit in fluid communication with the collection catheter; c) an injection catheter and an injection sensor; and d) an interface unit, the interface unit being electrically connected to each of the injection sensor, the collection sensor, and the aspiration unit, the interface unit controlling the operation of the collection catheter; e) wherein the collection sensor is external to the patient'"'"'s body during use of the system. - View Dependent Claims (26)

27. A system that removes a coronary artery injection of medium from a coronary sinus, the system comprising:
-
a) a collection catheter having a distal end positionable within a coronary sinus; b) an injection sensor that cooperates with an injection catheter; and c) an interface unit, the interface unit being electrically connected to the injection sensor, wherein the interface unit; i) establishes a start time of the coronary artery injection of medium when the injection sensor detects the injection of medium; ii) determines a volume of medium in the injection; and iii) initiates operation of the collection catheter a predetermined time after the start time of the injection, the initiation of operation occurring only when the volume of medium in the injection is greater than a predetermined amount. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A system that removes a medium from a coronary sinus, the system comprising:
-
a) a collection catheter having a distal end positionable within a coronary sinus, the collection catheter including a sensor, the sensor being located outside a patient'"'"'s body during use of the system; and b) an interface unit, the interface unit being electrically connected to the sensor, wherein the interface unit; i) initiates operation of the collection catheter to remove the medium from the coronary sinus;
orii) ceases operation of the collection catheter when the sensor detects an absence of the medium in the collection catheter. - View Dependent Claims (45, 46)
