Patent ID: 8689801

Claim:
An orthopaedic device comprising: an inductive electromagnetic sensor comprising: a non-cylindrical mounting platform comprising a printed circuit board comprising a polyamide polymer, the printed circuit board having a generally planar surface and an aspect ratio of greater than about 1.5:1, the mounting platform having a height and a width, the height being smaller than the width, wherein the height ranges from about 0.2 mm to about 1 mm, and the width is less than about 3 mm; and at least two sensor coils mounted to the generally planar surface of the printed circuit board, each of the at least two sensor coils defining a central axis, the at least two sensor coils configured to provide data indicating a position in six degrees of freedom in response to receiving electromagnetic fields; the at least two sensor coils being mounted to the generally planar surface of the printed circuit board in a generally co-planar fashion along the generally planar surface, the central axes of the sensor coils being oriented at an obtuse angle with respect to each other, the sensor coils not overlying each other, wherein each of the at least two sensor coils extends through the generally planar surface of the printed circuit board, each of the at least two sensor coils having a portion embedded in the printed circuit board and a portion that extends out of the printed circuit board.
