Abstract
In one aspect, an implant for replacing subject tissue includes a nonbiologic portion and a biologic portion grown on the nonbiologic portion. The biologic portion may be grown on the nonbiologic portion before being implanted in the subject. The nonbiologic portion may comprise a porous metal substrate (e.g., scaffolding). The nonbiologic portion may be formed by 3D printing (i.e., additive manufacturing). The nonbiologic portion may be patient-specific. A robot may be used to shape the implant before implantation and/or to shape bone being replaced/resurfaced.
Claims12
An implant for being implanted in a subject, the implant comprising:
- a three-dimensional (3D) printed shell configured to be implanted in an organ having a first tissue with a first tissue porosity and a second tissue with a second tissue porosity, the shell comprising a nonbiologic material that is formed by 3D printing the shell having a first porous region having a first porosity corresponding with the first tissue porosity and a second porous region having a second porosity corresponding with the second tissue property, wherein the first porous region overlies the second porous region;
- a first type of tissue ingrown by incubation into pores of the first porous region of the shell, wherein the first type of tissue comprises cartilage tissue;
- a second type of tissue different from the first type of tissue ingrown by incubation into pores of the second porous region of the shell, wherein the second type of tissue comprises bone.
