Abstract

A system and method is provided for an injectable substance delivery device comprising a limiter, shoulder or post, that controls how deep the needle is inserted into the tissue. The limiter is sized in proportions that control the maximum insertion depth of the needle into the tissue without excessively restricting the complete insertion of the needle. The system and method further comprises an normalization or stabilizer ring that prevents distortion of the tissue in the vicinity of the infusion, so that the needle length is the major determining factor as to how deep the infusion is delivered.
