Abstract

A system for determining a position of a medical device (24) within a body (26) is provided that reduces positional error by establishing a reference origin (38) closer to the device and/or simplifies the system by integrating components and functions. In one embodiment, a pair of drive electrodes (28) are affixed to opposed surfaces of the body (26) and create a pathway for transmission of current through a position sensor (36) related to the medical device (24). A pair of reference electrodes (46) proximate the drive electrodes (28) are coupled to a common reference node (50) outputting a reference signal establishing the reference origin (38). An electronic control unit (30) determines the position of the medical device (24) responsive to the position signal generated by the position sensor (36) and the reference signal. In another embodiment, a patch (62) affixed to an external surface of the body has a base layer (66) and multiple devices (68,70,72,74) supported on the base layer (66), electrically isolated from one another, and configured to perform different functions.
