Insertion set for a transcutaneous sensor
First Claim
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; and
an 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.

Abstract
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skin to carry the sensor electrodes to the desired subcutaneous site, after which the insertion needle can be slidably withdrawn from the insertion set.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.

22. 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, and further including a cable fitting generally at a rear end of said channel and adapted for releasable coupling with a cable connector, said channel extending from said cable fitting to a front end of said mounting base;
a flexible sensor having a head formed generally at a proximal end thereof, a proximal segment extending from said head and a distal segment having at least one sensor electrode thereon, said head including at least one contact pad conductively coupled to said electrode;
a protective cannula having said sensor distal segment and at a portion of said sensor proximal segment received therein;
said sensor proximal segment and a portion of said cannula being seated within said channel formed in said mounting base, with said sensor distal segment and the remainder of said cannula protruding from said mounting base;
a retainer cap mounted on said mounting base to close said channel and to engage the cannula portion therein to capture and retain said cannula portion and said sensor proximal segment within said channel; and
an insertion needle extending through the assembled retainer cap and mounting base, said cannula including means for engagement with said needle upon insertion of said needle through the assemble retainer cap and mounting base, said insertion needle being slidably withdrawable from said cannula and from said retainer cap and mounting base. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
