An improved 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 mounting base defining an upwardly open channel for receiving and supporting a flexible thin film sensor, in combination with a cap assembled with said mounting base to capture and retain a proximal end of the sensor within said channel. The sensor further includes a distal segment with sensor electrodes thereon which protrudes from the mounting base for transcutaneous placement, wherein the sensor distal segment is slidably carried by a slotted insertion needle fitted through the assembled base and cap. Placement of the insertion set against the patient's skin causes the insertion needle to pierce the skin to carry the sensor electrodes to the desired subcutaneous site, after which the insertion needle can be slidably withdrawn from the insertion set. The mounting base further includes a fitting and related snap latch members for mated slide-fit releasable coupling of conductive contact pads on a proximal end of the sensor to a cable connector for transmitting sensor signals to a suitable monitoring device.

[ What is claimed is:] [1.] A transcutaneous sensor insertion set, comprising:a mounting base adapted for mounting onto a patient's skin, said mounting base having an upwardly open channel formed therein;a flexible sensor having a proximal segment seated within said channel and a distal segment protruding from said mounting base with at least one sensor electrode thereon;a retainer cap mounted on said mounting base to close said channel for retaining said sensor proximal segment within said channel; andan insertion needle extending through said retainer cap and mounting base, said insertion needle defining means engageable with at least a portion of said sensor distal segment for transcutaneously placing said sensor distal segment and for subcutaneously placing said at least one electrode when said mounting base is placed against a patient's skin, said insertion needle being withdrawable from said sensor and said mounting base and retainer cap.
