Transcutaneous sensor insertion set
First Claim
1. 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, said proximal and distal segments being misaligned with respect to each other; and
a hollow insertion needle carried by said mounting base to protrude therefrom and having said distal segment of said sensor received 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 distal segment of said sensor.

Abstract
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 proximal and distal segments of the sensor are linearly offset or misaligned, with the distal segment fitted within the insertion needle for transcutaneous sensor placement with the needle as the mounting base is pressed onto the patient'"'"'s skin. The insertion needle can then be withdrawn to leave the sensor distal segment at the selected insertion position with the sensor electrodes in contact with patient blood or other extracellular fluid.

13. A transcutaneous sensor insertion set, comprising:
-
a mounting base adapted for placement onto a patient'"'"'s skin; a flexible sensor having a proximal segment carried by said mounting base, a distal segment protruding downwardly from said mounting base and having a tip end with at least one sensor electrode thereon, and a transition segment interconnecting said proximal and distal segments in axially misaligned relation; and a hollow insertion needle having a longitudinally elongated slot formed along one side thereof, said needle being slidably receivable through an open port formed in said mounting base in generally coaxial alignment with said sensor distal segment for slide-fit reception of said sensor distal segment within said needle, with said sensor transition segment extending through said needle slot; said insertion needle being positioned to pierce a patient'"'"'s skin to carry said sensor distal segment to an insertion position within the patient upon placement of said mounting base onto the patient'"'"'s skin, said insertion needle being slidably withdrawable from the patient'"'"'s skin and said mounting base to leave said sensor distal segment at the insertion position. - View Dependent Claims (14, 15, 16, 17, 18, 19)
