MAGNETIC FIELD-COMPATIBLE CONNECTOR USING MAGNETIC NOISE CANCELATION LOOPS

A medical device assembly (10) comprises a medical device (12) comprising a shaft (22) having proximal (24) and distal (26) end portions. The device further comprises a sensor (28) at the distal end portion of the shaft that comprises first (321) and second (322) leads extending therefrom to the proximal end portion (24) of the shaft. The device further comprises an electromechanical connector (30) having a plurality of pins (40) at a first end thereof. First (401) and second (402) of the pins are electrically connected to the first and second sensor leads, respectively, thereby forming a first partial magnetic loop between the first and second pins. The connector further comprises first and second jumpers (68) electrically connecting the first pin and third (403) pins, and second and fourth (404) pins, respectively, thereby forming a second partial magnetic loop. The partial magnetic loops are configured to combine with partial magnetic loops of a second connector (56), to which the first connector is mated, to form a pair of magnetic noise cancellation loops.
