Abstract:
1. A method of calibrating an implantable medical pump, comprising: attaching, to a blood pump, a calibration cannula that approximates an inflow cannula for the blood pump, the calibration cannula having a smooth surface corresponding to a region where the inflow cannula has a textured surface, the blood pump comprising a pump housing defining a passage therethrough and a rotor within the passage, the pump housing at least partially containing one or more elements configured to actuate the rotor to drive fluid through the passage; pumping a calibration fluid through the blood pump while the blood pump is attached to the calibration cannula; recording calibration variables based on a flow, a pressure, a speed, or a combination thereof of the calibration fluid pumped by the blood pump; and detaching the blood pump from the calibration cannula after pumping the calibration fluid through the blood pump.
