Abstract

An automated insertion assembly includes a first dermal perforation assembly configured to releasably engage a first subdermal device. A first actuation assembly is configured to drive the first dermal perforation assembly into a user'"'"'s skin to a first depth and drive the first subdermal device into the user'"'"'s skin to a second depth. The second depth is greater than the first depth.

8. The automated insertion assembly of claim 1 further comprising:

a second dermal perforation assembly configured to releasably engage a second subdermal device; and

a second actuation assembly configured to drive the second dermal perforation assembly into the user'"'"'s skin to a third depth and drive the second subdermal device into the user'"'"'s skin to a fourth depth.

9. The automated insertion assembly of claim 8 wherein the fourth depth is greater than the third depth.

10. The automated insertion assembly of claim 8 wherein the fourth depth is less than/equal to the third depth.

11. The automated insertion assembly of claim 8 wherein the second subdermal device is chosen from the group consisting of a canular assembly and a probe.
