Title
(EN) COMPOSITE STINT APPARATUS AND FABRICATION METHOD
(FR) APPAREIL À CANULE COMPOSITE ET PROCÉDÉ DE FABRICATION
Abstract
(EN) 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.
(FR) La présente divulgation concerne, de manière générale, une endoprothèse comportant une couche supplémentaire de graphène ajoutée à une canule qui sera insérée dans le corps d'un patient. Une telle canule peut être insérée dans une veine ou une artère d'un patient afin d'augmenter le débit sanguin, de maintenir le débit sanguin ou de prévenir l'affaissement d'une veine ou d'une artère. Le graphène ajouté à la canule confère une biocompatibilité améliorée de la canule et réduit les risques associés aux canules classiques. Les canules conformes à la présente divulgation peuvent également comprendre des facteurs de croissance qui aident à lier la canule à des récepteurs spécifiques ou à des cellules cibles. Les canules de la présente invention peuvent comprendre une monocouche, une bicouche ou des couches multiples de graphène adhérant à la surface de l'endoprothèse. La canule peut ensuite être revêtue d'un facteur de croissance.
