1. A sensing and infusion device comprising:
a first sensor strip having at least one working electrode; and
a catheter including:
an inner infusion lumen;
a first elongate sensor channel formed on an outer surface of the catheter external to the inner infusion lumen, the first sensor channel being open to an exterior of the catheter and configured to receive and hold the first sensor strip; and
an opening formed in a wall of the catheter separating the inner infusion lumen from the first sensor channel that provides access into the inner infusion lumen, the opening allowing for a distal portion of the first sensor strip to pass into the inner infusion lumen such that a distal end of the first sensor strip is disposed within the inner infusion lumen and the at least one working electrode remains within the first elongate sensor channel.
