Catheter including one or more sensors

A method comprising:

• sensing, with at least one sensor configured to be coupled to an elongated body defining a lumen the elongated body comprising a proximal portion and a distal portion, one or more parameters of a fluid within the lumen of the elongate body;
• storing, with a memory configured to be coupled to the elongated body, sensor calibration information;
• and
• calibrating the at least one sensor based on sensor calibration information stored by the memory.

A catheter system, comprising:

• an elongated body defining a lumen, the elongated body comprising a proximal portion and a distal portion;
• an anchoring member positioned on the proximal portion of the elongated body;
• a flow sensor configured to sense a flow rate of the fluid in the lumen;
• an oxygen sensor configured to sense the amount of oxygen within the fluid in the lumen;
• and
• memory configured to be coupled to the elongated body, the memory configured to store sensor calibration information, wherein the system is configured to calibrate the flow sensor and/or the oxygen sensor based on the sensor calibration information stored by the memory.
