(57) Summary An insertion set (10) is provided for percutaneously placing a sensor (12), such as a glucose sensor, at a selected site within a patient's body. The insertion set (10) has an insertion needle (14) extending through a mounting base (34) that can be attached to the patient's skin. The flexible thin film sensor (12) projects from the mounting base (34) and is percutaneous, with a proximal segment (20) supported by the mounting base (34) and electrically connectable to a suitable monitor (24). A distal segment (16) with a sensor electrode (18) arranged. The distal segment (16) of the sensor (12) and the distal segment (66) of the insertion needle (14) are located within a flexible cannula (15) extending from the mounting base (34). Thus, when the mounting base (34) is attached to the patient's skin, the insertion needle (14) pierces the skin and the cannula (15) with the sensor (12) mounted therein is placed percutaneously. It |
