Abstract
Various embodiments disclosed relate to an implant including a crosslinked iodine-infused polyethylene. In various embodiments, the implant can be made by exposing the polyethylene to a source of iodine such that the polyethylene is infused with iodine. In various embodiments, a method of preventing microbe formation on or around an implant includes implanting a crosslinked iodine-infused implant comprising polyethylene, wherein iodine is released gradually from the implant after the implantation.
Claims7
An implant comprising:
- a consolidated, anti-microbial material, formed of ultra high molecular weight polyethylene (UHMWPE) infused with iodine, an average concentration of the iodine in the anti-microbial material being within a range of 5 to 3000 micrograms per cubic centimeter (μg/cm3), wherein the UHMWPE comprises crosslinking formed by an irradiation treatment;
- wherein the infused iodine of the consolidated, anti-microbial material is water-soluble, such that when the material is placed in an aqueous environment, the material releases at least some of the infused iodine into the aqueous environment;
- and
- wherein the infused iodine is held in amorphous regions of the anti-microbial material.
