NEOVEIL™ SHEET

NEOVEIL is an absorbable reinforcement felt made of PGA (polyglycolic acid). It is used to reinforce soft tissue and to prevent air or fluid leakage.

Features

NEOVEIL can be used in areas of the body that do not take a long time to heal. Once it is in the body, it degrades via hydrolysis and is fully absorbed approximately 15 weeks after surgery.
Gunze produces a variety of sizes and thicknesses to make NEOVEIL SHEET easily appliable to different areas of the body.

NEOVEIL SHEET can be applied using sutures, staples, fibrin glue, or any suitable alternative, according to the preferences of the surgeon.
