1. An integrated inserter, comprising:
- a body comprising a needle hub and needle;
a spring disposed in said body and configured to urge said needle hub and needle into a down position upon release, wherein said spring is configured to insert said needle into the skin at a controlled rate of speed; and
a release mechanism, configured to releasably secure at least one of said spring and said needle hub in an up position and to release at least one of said spring and said needle hub from said up position when pulled free from said body.

Abstract
An infusion set has an integrated ballistic inserter that can insert a needle at a controlled high rate of speed to a depth to deliver content to the upper 3 mm of skin surface, and a skin securing, adhesive layer to secure the skin surface at the insertion site such that the inserter that can insert a needle without a risk of tenting of the skin surface. A driving spring of the ballistic inserter is captured within the ballistic inserter, and can be released by user operation, to insert a needle at such a controlled rate of speed.
