  • Patent number: 9574060
    Abstract: A method for immobilizing dyes and antimicrobial agents on a polymeric cover or housing for a medical device is disclosed and described. The surface may be that of a catheter, a connector, a drug vial spike, a bag spike, a prosthetic device, an endoscope, a surface of an infusion pump, a key pad, a touch screen or a handle. The surfaces may also be one or more of those associated with a infusion of a medicament or dialysis treatment, such as peritoneal dialysis or hemodialysis, where it is important that the working surface for the dialysis fluid be sterile. These surfaces include connectors for peritoneal dialysis sets or for hemodialysis sets, bag spikes, dialysis catheters, and so forth. A method for determining whether a surface has been sterilized, and a dye useful in so indicating, is also disclosed.

  • Patent number: 7135156
    Abstract: Methods of producing zirconium oxide compositions and using same are provided. The zirconium oxide compositions in crystalline form can be prepared by a synthetic process wherein the hydrolysis of zirconyl chloride and particle formation can be achieved simultaneously. Alternatively, the particle formation can occur first and then followed by hydrolysis with a base solution. The processes utilize a zirconyl salt solution that includes a zirconyl salt in isopropanol and water.
