"The Chitogel Endoscopic Sinus Surgery Kit contains components and equipment for the preparation of a nasal gel to be applied to the sinus cavities via a supplied and specifically designed malleable cannula.~The Gel preparation will take approximately 30 minutes, so preparation must start sufficiently in advance of when the Gel is expected to be used in surgery.~Once the Gel has been prepared it should be applied to the sinus cavities on both sides within six hours using the malleable cannula supplied with the Kit.~The Gel must be prepared on a sterile surface following these instructions. There are two main components to the Gel.~1. Dextran Aldehyde (B), which is a dry powder, and is reconstituted into a liquid form through mixing the powder with a liquid Sodium Phosphate Buffer (A). Both of these components are supplied sterile.~2. The second component Chitosan Succinamide (C), is a liquid and is also supplied sterile."
