ABSTRACT:
The present invention provides apparatus, systems, and methods for accurately calibrating a pressure sensor which is incorporated into a lead, e.g., a pacemaker lead, prior to implant into a patient. A calibration vessel is provided which has a housing which forms a reservoir for containing the portion of the lead having the pressure sensor. The vessel also has a connector for receiving a reference pressure into the reservoir, and a sealable opening for receiving the distal end of the lead that carries the pressure sensor. The calibration vessel can be used in a system comprising an electronic display module and an external pressure reference, for establishing an accurate sensor baseline for zero pressure; and can also be used in a system comprising an electronic display module, a reference pressure input source, and a manometer for establishing an accurate scale factor for the lead pressure sensor.
