1. A surgical indicator to indicate the proper formation of a surgical element comprising:
- a member having a modulating property, wherein the member modulates from a first condition when no stress is applied to another second condition when a stress is applied; and
wherein the modulating property is configured to provide an indication when compressed to a predetermined compression stress level, wherein the predetermined compression stress level indicates an optimal tissue compression of the tissue type, the indication being a tissue state that is optimal for the formation of the surgical element for the predetermined tissue type.

Abstract
An apparatus for supporting tissue during compression prior to the insertion of a surgical element into the tissue has a substrate. The substrate is made from a predetermined material. The predetermined material has a thickness and a predetermined stress strain profile. The predetermined stress strain profile is complementary to a stress strain profile of the tissue and permits the substrate to support the tissue when the surgical element is delivered into the tissue. The substrate provides hemostasis control of the tissue when the surgical element is delivered into the tissue.

22. A method of determining an optimal amount of compression of tissue to provide an indication to the surgeon of the optimal compression and a time to fire a surgical element into tissue, the method comprising:
-
applying a pressure sensitive film to tissue, the pressure sensitive film configured to provide an indication when compressed to a predetermined compression stress level, wherein the film is tuned such that the predetermined compression stress level indicates the optimal tissue compression of the tissue type;
compressing the pressure sensitive film and the tissue; and
firing the instrument when the pressure sensitive film provides a visual indication.
