1. A medical device for use inside a body of a mammalian subject, the device comprising:
- a casing adapted for insertion into the body of the mammalian subject, the casing having an outer surface and comprising an insulating material surrounding a conductive area made of an electrically-conductive material, the conductive area fastened and sealed to the insulation material; and
a transmitter, which is adapted to generate an electrical signal and is encapsulated in the casing and coupled to the conductive area so that the electrically-conductive area of the outer surface serves as an antenna for transmitting the signal to a receiver outside the body, the signal being a position signal indicative of six-dimensional position and orientation including X, Y, Z directions and pitch, yaw and roll orientations.

Abstract
A medical device, for use inside a body of a mammalian subject, includes a casing adapted for insertion into the body of the mammalian subject, the casing having an outer surface and including an insulating material and an electrically-conductive material, which are arranged so that an area of the outer surface of the casing is electrically conductive. A transmitter is adapted to generate an electrical signal and is encapsulated in the casing and coupled to the conductive material so that the electrically-conductive area of the outer surface serves as an antenna for transmitting the signal to a receiver outside the body.

14. A method for transmitting a signal from inside a body of a mammalian subject, the method comprising:
-
encapsulating an electronic device comprising a transmitter in a casing having an outer surface and comprising an insulating material surrounding a conductive area made of an electrically-conductive material, the conductive area fastened and sealed to the insulating material; coupling the transmitter to the conductive material so that the electrically-conductive area of the outer surface serves as an antenna for the transmitter; inserting the casing containing the device into the body of the mammalian subject; and transmitting the signal from the transmitter within the body via the antenna to a receiver outside the body, the signal being a position signal indicative of six-dimensional position and orientation including X, Y, Z directions and pitch, yaw and roll orientations. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
