Regional Flow Catheter

The golden standard for the measurement of flow in blood vessels is the indicator dilution method.  A first requirement for the proper flow measurement is complete mixing of the indicator in the blood stream. The indicator dilution method  can only be used to measure cardiac output, as the right ventricle is used as a mixing chamber. We developed a method that does not require a complete mixing of the indicator. The method is based on the change of the conductance of blood due to the indicator. The invented regional flow catheter  measures flow based on change in the conductance of blood due to the indicator injection. Thus flow may be measured at any point in the circulatory system. This device is patented.  (Reference to the patent)
