Abstract:
A single-use, disposable circulation set for a heat transfer catheter, comprising: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 said catheter from said fluid reservoir; 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; 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 said fluid reservoir, pump, filter assembly, heat exchanger, and temperature and pressure sensor block member, and adapted to be connected to said catheter for supplying heat transfer fluid to said catheter; and a single-use, disposable return line communicating said temperature and pressure sensor block member and fluid reservoir, and adapted to be connected to said catheter for returning heat transfer fluid to said fluid reservoir, wherein said single-use, disposable temperature and pressure sensor block member includes a supply lumen in communication with said supply line and a return lumen in communication with said return line.
