An antibiotic-eluting article for implantation into a mammalian subject, produced by an additive manufacturing process wherein a polymeric material is concurrently deposited with a selected antibiotic. The additive manufacturing process may be a selective laser sintering process or a selective laser melting process or a selective heat sintering process or an electron beam melting process. The antibiotic-eluting article may be temporary or permanent orthopedic skeletal component, an orthopedic articulating joint replacement component, and/or an external hard-shell casing for an implantable device. One or more bone-growth-promoting compositions may be concurrently deposited with the polymeric material. The implantable device may be a cardiac pacemaker, a spinal cord stimulator, a neurostimulation system, an intrathecal drug pump for delivery of medicants into the spinal fluid, and infusion pump for delivery of chemotherapeutics and/or anti-spasmodics, an insulin pump, an osmotic pump, and a heparin pump.
一种用于植入哺乳动物体内的抗生素洗脱物品,通过添加制造工艺生产,其中聚合物材料与所选抗生素同时沉积。快速成型制造工艺可以是选择性激光烧结工艺或选择性激光熔化工艺或选择性热烧结工艺或电子束熔化工艺。抗生素洗脱制品可以是临时或永久性骨科骨骼组件、骨科关节置换组件和/或植入式装置的外部硬壳外壳。一种或多种促进骨生长的组合物可与聚合物材料同时沉积。植入式装置可以是心脏起搏器、脊髓刺激器、神经刺激系统、向脊髓液输送药物的鞘内药物泵、输送化疗药物和/或抗痉挛药物的输液泵、胰岛素泵、渗透泵和肝素泵。
