MODULAR IMPLANTABLE MEDICAL PUMP

摘要

An implantable medical pump system can include a blood pump comprising a pump housing defining a passage therethrough and a rotor within the passage. The blood pump further includes one or more elements at least partially contained within the housing adapted to actuate the rotor to drive fluid though the passage. The pump housing includes at least one coupling feature. The system further includes an inflow cannula defining a lumen therethrough. The inflow cannula is adapted to be mechanically coupled to the at least one coupling feature.

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.
