Abstract

The invention provides a single-use, disposable circulation set for a heat transfer catheter. The circulation set includes a single-use, disposable fluid reservoir adapted to supply a heat transfer fluid to the catheter, a single-use, disposable pump adapted to pump heat transfer fluid through the catheter from the fluid reservoir, a single-use, disposable filter assembly adapted to remove impurities from the heat transfer fluid, a single-use, disposable heat exchanger member adapted for use with a heat exchanger for transferring heat between the heat exchanger and the fluid, a single-use, disposable temperature and pressure sensor block member for use with a multi-use, non-disposable temperature and pressure sensor electronics member, a single-use, disposable supply line communicating the fluid reservoir, pump, filter assembly, heat exchanger, and temperature and pressure sensor block member, and adapted to be connected to the catheter for supplying heat transfer fluid to the catheter, and a single-use, disposable return line communicating the temperature and pressure sensor block member and fluid reservoir, and adapted to be connected to the catheter for returning heat transfer fluid to the fluid reservoir.

Claims

1. A single-use, disposable circulation set for a heat transfer catheter, comprising:

a single-use, disposable IV bag adapted to supply a heat transfer fluid to the catheter;

a single-use, disposable pump adapted to pump heat transfer fluid through said catheter from said IV bag;

a single-use, disposable filter assembly adapted to remove impurities from said heat transfer fluid;

a single-use, disposable heat exchanger member adapted for use with a heat exchanger for transferring heat between said heat exchanger and said fluid, wherein said heat exchanger member is an IV bag adapted to be removably disposed between a pair of heat exchanger molds;

a single-use, disposable supply line communicating said IV bag, pump, filter assembly, and heat exchanger, and adapted to be connected to said catheter for supplying heat transfer fluid to said catheter; and

a single-use, disposable return line adapted to be connected to said catheter for returning heat transfer fluid to said IV bag.

2. The circulation set of claim 1, wherein said circulation set includes an air-removal mechanism.

3. The circulation set of claim 2, wherein said IV bag includes the air-removal mechanism.

4. The circulation set of claim 2, wherein said outlet of said return line is located closer to said air-removal mechanism than the inlet of said supply line.

5. The circulation set of claim 4, wherein said outlet of said return line is located adjacent to said air-removal mechanism.

6. The circulation set of claim 1, wherein said return line terminates at an outlet inside said IV bag and said supply line terminates at an inlet inside said IV bag.

7. The circulation set of claim 1, wherein said heat exchanger member is adapted to be used with a dry heat exchanger so that an outer surface of said heat exchanger member does not contact a heat transfer liquid.

8. The circulation set of claim 1, wherein said IV bag is adapted to be shaped into a serpentine heat transfer fluid path.

9. A single-use, disposable circulation set for a catheter, comprising:

a single-use, disposable fluid reservoir adapted to supply a heat transfer fluid to the catheter;

a single-use, disposable heat exchanger member adapted for use with a heat exchanger for transferring heat between said heat exchanger and said fluid, wherein said heat exchanger is an IV bag adapted to be removably disposed between a pair of heat exchanger molds;

a single-use, disposable supply line communicating said fluid reservoir and said heat exchanger, and adapted to be connected to said catheter for supplying heat transfer fluid to said catheter; and

a single-use, disposable return line adapted to be connected to said catheter for returning heat transfer fluid to said fluid reservoir.

10. A method of using a circulation set for a heat transfer catheter, comprising:

providing a single-use, disposable circulation set for the catheter, comprising;

a single-use, disposable IV bag adapted to supply a heat transfer fluid to the catheter;

a single-use, disposable pump adapted to pump heat transfer fluid through said catheter from said IV bag;

a single-use, disposable filter assembly adapted to remove impurities from said heat transfer fluid;

a single-use, disposable heat exchanger member adapted for use with a multi-use, non-disposable heat exchanger for transferring heat between said heat exchanger and said fluid, wherein said heat exchanger member is an IV bag adapted to be removably disposed between a pair of heat exchanger molds;

a single-use, disposable supply line communicating said IV bag, pump, filter assembly, and heat exchanger, and adapted to be connected to said catheter for supplying heat transfer fluid to said catheter; and

a single-use, disposable return line adapted to be connected to said catheter for returning heat transfer fluid to said IV bag;

connecting said return line and supply line to said catheter;

coupling said single-use, disposable heat exchanger member with said multi-use, non-disposable heat exchanger;

circulating heat transfer fluid and controlling the flow rate and temperature of the same through said catheter with said pump, and said heat exchanger;

disposing said circulation set after a single use.

11. The method of claim 10, wherein said circulation set includes an air-removal mechanism.

12. The method of claim 10, wherein said IV bag includes an air-removal mechanism.

13. The method of claim 12, wherein said return line terminates at an outlet inside said IV bag and said supply line terminates at an inlet inside said IV bag.

14. The method of claim 13, wherein said outlet of said return line is located closer to said air-removal mechanism than the inlet of said supply line.

15. The method of claim 14, wherein said outlet of said return line is located adjacent to said air-removal mechanism.

16. The method of claim 10, wherein said heat exchanger member is adapted to be used with a dry heat exchanger so that an outer surface of said heat exchanger member does not contact a heat transfer liquid.

17. The method of claim 10, wherein said IV bag is adapted to be shaped into a serpentine heat transfer fluid path.
