TissueDerm is a form of artificial skin that combines polycaprolactone (PCL) mesh and collagen sheets manufactured using a 3D printer, and is used for reinforcement and reconstruction of tissue defects or damaged soft tissues (breast reconstruction, etc.).The role of the collagen sheet is to naturally fusion with the patient's tissue, promoting tissue regeneration and fixing the silicone implant. And the role of biodegradable PCL is to solve tissue adhesion problems that may occur due to long-term implant use and to support silicone implants.
