20150139913 | MEDICAL USE OF PARTICLES OF TITANIUM AND/OR TITANIUM OXIDE - The present invention describes particles of titanium, titanium alloy, at least one type of titanium oxide or a combination thereof, wherein at least a substantial amount of the particles are of micrometer-millimeter size and are non-spherical, for use as an X-ray contrast agent. The irregular shapes and/or internal pores and cavities of said particles lead to a prolonged retention time in the gastrointestinal tract leading to a longer time period available for X-ray examination. Further, the particles are not only chemically inert, they also exhibit an anti-inflammatory and anti-bacterial effect on the surrounding tissue. | 05-21-2015 |
