Abstract
Embodiments of the invention described herein thus provide implants and methods for manufacturing an implant having an outer layer that is porous. The porous outer layer can help encourage tissue ingrowth into the implant. The porous outer layer may be positioned around a core structure this is solid or that has a hollow interior. The core structure may be spherical or any other appropriate shape for a medical implant.
Claims15
A two-part facial implant, comprising:
- a first part comprising a flexible silicone core material comprising an outer surface that functions as a barrier to tissue ingrowth;
- a second part comprising a porous outermost layer surrounding and fully encapsulating the core material with an outer cortex of polytetrafluoroethylene (PTFE) particles that is at least two particles thick fully encapsulating the first part, wherein the porous outermost layer allows tissue ingrowth, wherein the porous outermost layer is about 0.25 mm-1.5 mm thick.
An implant, comprising:
- a hollow body manufactured from two halves that are thermally processed together, the hollow body halves comprising an interior coating of a flexible silicone that prevents tissue ingrowth, and a porous outer surface that encourages tissue ingrowth, the porous outer surface comprising an outermost layer surrounding and fully encapsulating the flexible silicone interior coating with an outer cortex of polytetrafluoroethylene (PTFE) particles that is at least two particles thick fully encapsulating the flexible silicone interior coating, wherein the layer is about 0.25 mm-1.5 mm thick.
