A transdermal introducer assembly is provided for quick and easy transcutaneous placement of a medical tube on a patient with reduced patient discomfort. The introducer assembly comprises a medical tube segment defining a hollow lumen extending between a distal end for placement into the subcutaneous tissue and a proximal end disposed outside the patient. The tube segment is assembled in side-by-side relation with a hollow introducer needle, and includes an elongated introducer thread at the distal end thereof folded back for slide-fit reception into the open distal end of the introducer needle. In use, the introducer needle is deployed to pierce the patient's skin at a selected placement site and to carry the tube segment to the desired transcutaneous position, after which the introducer needle can be withdrawn and slidably separated from the introducer thread to leave the tube segment and thread in place on the patient. A window is formed in the tube segment near the distal end thereof and, in a preferred form, exposes a transcutaneous sensor carried within the tube segment to patient body fluids.
