|20120316447||SYSTEM AND METHOD FOR DIVERTING FLOW TO FACILITATE MEASUREMENT OF SYSTEM PARAMETERS - A method facilitating the measurement of hemodynamic parameters by injection of an indicator in an indicator dilution technique using an extracorporeal circuit connected to a patient, includes reducing a pressure spike associated with the introduction of the indicator into the extracorporeal circuit. The method diverts blood flow during an indicator introduction and then returns the diverted blood back into the extracorporeal circuit after the introduction is completed.||12-13-2012|
|20120165689||CATHETER WITH COMMON GUIDE WIRE AND INDICATOR LUMEN - A catheter for retrograde orientation in a blood flow is used to determine the blood flow rate by thermodilution measurements. The determination of the blood flow rate accommodates injectate induced thermal influences on a dilution thermal sensor, wherein the thermal influences can occur prior to introduction of the injectate into the blood flow.||06-28-2012|
|20090143673||TRANSIT TIME ULTRASONIC FLOW MEASUREMENT - A transcutaneous energy transfer system with subcutaneous non coupled coils is used to transmit power and signals to an implanted biological support device or sensor, such as a flow sensor for measuring relatively low flow rates, such as hydrocephalic shunt flow. The flow sensor is configured to convert a shear wave generated by a transducer to a longitudinal wave at the interface of a signal pathway and the flow, wherein the longitudinal wave travels parallel to the flow and exits a flow channel to convert to a shear wave which intersects a second transducer. The transcutaneous energy transfer employs a pair of inductive coupling coils, wherein the coils are disposed in zero coupling orientation which can include a perpendicular orientation of corresponding coil axes.||06-04-2009|
