COMPOSITE STINT APPARATUS AND FABRICATION METHOD

摘要

The present disclosure is generally related to a stent with one more layer of graphene added to a stint that will be inserted into the body of a patient. Such a stint may be inserted into a vein or artery of a patient in order to increase blood flow, to maintain blood flow, or to prevent a vein or artery from collapsing. The graphene added to the stint provides improved biocompatibility of the stint and reduces risks associated with conventional stints. Stints consistent with the present disclosure may also include growth factors that help bind the stint to specific receptors or target cells. Stints of the present disclosure may include a monolayer, a bilayer, or multi-layers of graphene adhered to the surface of the stent. The stint may then coated with a growth factor.
