Latest Patents

Messana's latest patents include a system for determining blood flow rate in a vessel using diverted flow measurements. This innovative system and method are designed to assess the performance of a vessel, such as a hemodialysis access point, which facilitates blood communication between two locations in a patient. The system incorporates a conduit, such as an external dialysis circuit or an intravascular catheter, that is in fluid communication with the vessel. It features a diversion point for redirecting blood from the vessel into the conduit. The system also includes mechanisms for determining the flow rate of the diverted blood through the conduit. A first sensor, which is in communication with the vessel, generates signals that reflect the blood flow rate downstream from the diversion point. This downstream flow rate is influenced by the conduit flow rate, allowing for performance assessment of the vessel based on the generated signals. A processor can be integrated to determine the upstream flow rate in the vessel from the signals and conduit flow rate. In preferred embodiments, the first sensor is an ultrasonic sensor, providing a time-averaged mean Doppler velocity of blood flow. Additional sensors may also be utilized to measure both upstream flow rates and conduit flow rates.
