<qa>  What is the liquid that is applied to a bleeding area?PuraStat 3-D Matrix Ltd, Tokyo is a liquid which is applied to a bleeding area which acts rapidly to form a gel coat which induces haemostasis. This transparent adherent barrier permits further endoscopic therapy to be performed. It can be applied in the general area of bleeding and does not require precise application to the exact point of bleeding. It is applied through a small catheter placed through the biopsy channel of the endoscope which can be used in very small spaces.
