System, method and apparatus for sensor insertion
First Claim
1. A sensor insertion tool for inserting a sensor through intact skin without a cannula or trocar, comprising:
- a channel guide assembly, comprisinga channel guide, anda channel guide cover, wherein the channel guide and the channel guide cover together form a channel guide assembly channel;
a motive force assembly to store and release energy, comprisinga motive force member,a hammer channel separate from and non-contiguous with the channel guide assembly channel, and having a curved portion,a hammer extending through the channel guide cover into the channel guide assembly channel, anda hammer pin coupled to and extending transverse from the hammer, the hammer pin configured to extend from the hammer into the hammer channel and move along the curved portion of the hammer channel to guide the hammer to strike a sensor subassembly positioned within the channel guide assembly channel;
a cocking assembly coupled to the motive force assembly to load energy into the motive force assembly; and
a trigger assembly having a trigger member coupled to the motive force assembly to release stored energy in response to actuation of the trigger member.

Abstract
Embodiments provide a sensor insertion tool (SIT) that provides a motive force for insertion of an analyte sensor into/through skin. A SIT may be releasably locked to one or more components of a sensor insertion system, such that components of the sensor insertion system remain securely coupled during sensor insertion. A SIT may include a release member that unlocks or uncouples the SIT and the other components after sensor insertion. In various embodiments, a SIT may be a component of a sensor insertion system configured for assembly by an end user, a health care professional, and/or a caretaker prior to sensor insertion, and may act in cooperation with other sensor insertion system components. Additional components and methods of assembly and use are also provided herein.
