Abstract
A system and method for precisely controlling the delivery of two fluids to a specific organ or region of a patient when one of the fluids breaks down the other fluid. The fluids are separately metered and are maintained in separate delivery lines until a point very near the target organ, preferably within twelve inches of the delivery site. In an exemplary embodiment, blood and a cardioplegic agent are supplied to the heart via the coronary arteries or coronary veins while adenosine, which provides a powerful protective influence on the myocardial cells during ischemia, is provided in a separate delivery line to prevent the breakdown of adenosine, which has a half-life of 13 seconds in the blood.
Claims58
A clinical fluid pumping system comprising:
- a first pump that is configurable to pump a first metered amount of a first fluid through a first delivery line to a catheter;
- a second pump that is configurable to pump a second metered amount of a second fluid through a second delivery line, separate from said first delivery line, to said catheter;
- a processor, connected to control said first and said second pumps such that said second metered amount has a definable relationship to said first metered amount;
- wherein the lumen of said first delivery line and the lumen of said second delivery line remain separate up to a connection point of said first and second delivery lines to said catheter.
A clinical fluid pumping system, comprising:
- a first delivery line for receiving a first fluid;
- a second delivery line for receiving a second fluid;
- and
- pumping means connected to advancing the first and second fluids through their respective said delivery lines in a known relationship to each other;
- wherein said first delivery line and said second delivery line prevent the co-mingling of the first fluid and the second fluid up to a connection point of said first and second delivery lines to a catheter.
A method of providing a therapeutic agent to a targeted portion of the vascular system of a patient, said method comprising the steps of:
- providing a fluid pumping system;
- receiving a supply of a first fluid into said fluid pumping system;
- pumping the first fluid at a measured rate to a first delivery line attached to a catheter;
- and
- metering a given amount of a second fluid to a second delivery line for delivery to said catheter, wherein the second fluid is delivered at a rate that is tied to the delivery rate of the first fluid;
- wherein the first fluid in said first delivery line and the second fluid in said second delivery line are not co-mingled at least until delivery into said catheter.
