NOVELTY - Graphene type heart support comprises 25-36 pts. wt. graphene, 45-62 pts. wt. polylactic acid, 35-48 pts. wt. polybutylene adipate and 18-50 pts. wt. polyglyceryl sebacate. USE - The graphene heart support is used in cardiac interventional operation. It is used for dredging artery blood vessel. It can be used for clinical treatment. ADVANTAGE - The method is simple, economical and environmentally-friendly; low needed printing temperature; low heat energy consumption; high prepared heart support and human affinity; it can reduce rejection reaction of human body to the heart support, it has important meaning in the cardiac interventional operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the graphene type heart support.
