Abstract
A cannula for insertion of a medical instrument includes a tube portion and an attachment portion coupled to the tube portion. One or more magnets are arranged at the attachment portion and configured to encode identifying information of the cannula. The attachment portion comprises a plurality of encoding positions that each indicate part of the identifying information; and for each encoding position of the plurality of encoding positions, absence of one of the one or more magnets at the respective encoding position indicates a first value, presence of one of the one of the magnets with a first orientation at the respective encoding position indicates a second value, and presence of one of the one of the magnets with a second orientation at the respective encoding position indicates a third value.
