An implantable stent is coated with a material that attracts heparin and with which heparin forms a bond. The stent is exposed to a heparin containing solution just prior to implantation or is first implanted and then exposed to heparinized blood. As heparin becomes detached from the stent, the implantation site is exposed to heparin to restore an effective level and thereby prevent thrombosis.
Un extenseur implantable est enrobé d'un matériau qui attire l'héparine et auquel se lie l'héparine. L'extenseur est exposé à une solution contenant de l'héparine juste avant l'implantation ou est d'abord implanté et ensuite exposé à du sang héparinisé. € mesure que l'héparine se dégage de l'extenseur, le site de l'implantation est exposé à de l'héparine pour rétablir un taux efficace et ainsi prévenir la thrombose.
