1. A processing system including a processing unit for a catheter comprising:
a housing containing the processing unit;
a connector portion of the housing configured to be insertable into an opening of a proximal end portion of the catheter, the connector being configured to be connected to the catheter in a releasable fashion and configured to exchange measurement and calibration data (M, C) with a component of the catheter and at least one of a database, a computer network, and a computer device, wherein the processing unit comprises an integrated circuit for processing said data, wherein the connector portion comprises electrically conductive contacts each configured to contact an associated contact of the catheter, wherein the proximal end portion of the catheter comprises a proximal opening of an outer shaft of the catheter and wherein the connector portion and the proximal opening form a two-part Luer system,
wherein the connector portion comprises first and second projections configured to guide, engage and form a snap-in connection with first and second recesses of the proximal end portion of the opening of the outer shaft of the catheter, and
wherein openings of the first and second recesses have different dimensions.
