An insertion set is provided for transcutaneous placement of a sensor such as a glucose sensor at a selected site within the body of a patient. The insertion set comprises a slotted insertion needle extending through a mounting base adapted for mounting onto the patient\s skin. A flexible thin film sensor includes a proximal segment carried by the mounting base and defining conductive contacts adapted for electrical connection to a suitable monitor, and a distal segment protruding from the mounting base with sensor electrodes for transcutaneous placement. The distal segment of the sensor extends within a protective cannula, a portion of which is slidably disposed within the insertion needle. Placement of the mounting base onto the patient\s skin causes the insertion needle to pierce the skin for transcutaneous placement of the cannula with the sensor therein. The insertion needle can then be withdrawn to leave the cannula and sensor at the selected insertion position, with the sensor electrodes being exposed to patient blood or other extracellular fluid via a window formed in the cannula.

A transcutaneous sensor insertion set, comprising: a mounting base adapted for mounting onto a patient\s skin; a flexible sensor having a proximal segment carried by said mounting base, and a distal segment protruding from said mounting base and having at least one sensor electrode thereon; a cannula protruding from said mounting base and having said sensor distal segment therein, said cannula defining at least one window disposed generally in alignment with said at least one sensor electrode on said sensor distal segment; and a hollow insertion needle carried by said mounting base to protrude therefrom and having at least a portion of said cannula nested therein, said insertion needle defining a longitudinally extending slot along one side thereof to permit sliding withdrawal of said needle from said mounting base and said nested portion of said cannula.
