A medical device such as a cannula, catheter, needle or biosensing probe includes an elongated body for penetrating, inserting and/or positioning in or through the skin of a patient. The elongated body has an outer surface that when positioned in the patient with a coefficient of friction sufficient to inhibit movement between the elongated body on the skin at the insertion site to inhibit irritation at the infusion site. A lubricious coating is provided on the elongated body to assist in penetration and/or insertion of the elongated body into the patient. The lubricious coating can be removed by a shearing action by the insertion of the elongated body into the patient and/or by absorption of the lubricious coating to expose the outer surface of the elongated member.
