ABSTRACT:
A multi-lumen catheter capable of measuring cardiac output continuously, mixed venous oxygen saturation as well as other hemodynamic parameters. The catheter is also capable of undertaking therapeutic operations such as drug infusion and cardiac pacing. The catheter includes optical fibers for coupling to an external oximeter, an injectate port and thermistor for bolus thermodilution measurements, a heating element for inputting a heat signal and for coupling to an external processor for continuously measuring cardiac output, and a distal lumen for measuring pressure, withdrawing blood, guidewire passage or drug infusion. In a preferred embodiment, the catheter includes a novel lumen configuration permitting an additional infusion lumen for either fast drug infusion or cardiac pacing.
