  • Thermodilution catheter
    Patent number: 10350385
    Abstract: A system includes an outer catheter and an inner catheter. The outer catheter has a proximal end and a distal end. The distal end has a discharge nozzle, a tapered interior wall, and an end orifice. The proximal end is configured to receive a fluid. The discharge nozzle is coupled to the proximal end by a first lumen. The discharge nozzle is configured to direct the fluid in a plurality of discrete streams aligned in a radial fashion about an axis of the first lumen. The interior catheter is configured for placement within the first lumen. A first end of the interior catheter includes an occluder and includes a first temperature sensor. The first temperature sensor is configured to pass through the end orifice. The occluder is configured to engage with the tapered interior wall in a fluid-tight seal. The first temperature sensor includes a sense surface and includes a signal node. The signal node is configured to provide a first signal corresponding to a timewise change in temperature at the sense surface.
