Method of forming tissue ingrowth surface on surgical implants. |
摘要 |
<p>A method of producing a site for tissue ingrowth on a surgical implant (20) by embedding a space occupier (10) possessing a desired pattern (14) in the surface (24) of the implant (20) at the desired location (22) for ingrowth and then solubilizing the embedded space occupier (10) to leave the pattern (14) on the implant surface (24). Preferably, the implant (20) is fabricated from a composite comprising a semi-crystalline thermoplastic resin such as polyetheretherketone or polyphenylene sulfide, and the space occupier (10) is an acid-soluble metal plate machined to produce the desired pattern (14) and removed by aqueous acid solution.</p> |
