1. An infusion set configured to be secured to a skin surface for targeting a desired depth to deliver content to an upper skin surface, comprising:
- a slidable top cover enclosing;
a main hub configured to be secured to said skin surface, said main hub including an insertion track; and
a needle hub fixed to a needle, a base of said needle being configured to pivot while traveling during insertion on said insertion track as urged by a motion from a user;
whereinsaid needle is configured to assume a first angle relative to said skin surface in a free state;
when said main hub is secured to said skin surface, said needle deflects at an angle relative to said skin surface that is different from said first angle of said needle;
said motion is applied to said needle to insert said needle into said skin surface; and
said needle returns toward said first angle relative to said skin surface during said motion.

Abstract
An infusion set configured to be secured to a skin surface for targeting a desired depth to deliver content to an upper skin surface, comprising a hub and a needle configured to travel during insertion as urged by a motion, wherein said needle is configured to assume a first angle relative to said skin surface in a free state, and wherein said needle is configured to return toward said first angle relative to said skin surface upon release of said motion, wherein said motion is at an angle relative to said skin surface that is different from said first angle of said needle.

9. A method for targeting a desired depth to deliver content to an upper skin surface, comprising the steps of:
-
enclosing a main hub and a needle hub in a slidable top cover; disposing a needle fixed to said needle hub at a first angle relative to said skin surface in a free state; securing said main hub on a skin surface, said main hub including an insertion track, wherein said needle deflects to an angle relative to said skin surface that is different from said first angle; and applying a motion to said needle to insert said needle into said skin surface, said needle returning toward the first angle relative to said skin surface;
whereina base of said needle pivots while traveling on said insertion track during said motion. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
