Bohdan Wolodymyr Chopko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190357954
    Abstract: Described herein are devices, systems and methods for treating disease and/or infection by the release of silver from an implant over an extended period of time. In particular, the devices described herein may be used to treat infections such as osteomyelitis by the controlled release of silver ions from multiple sites of an extended-use implant. This implant typically includes a plurality of arms that both anchor and help distribute the released ions within the tissue. Power may be applied to release the silver ions into the tissue.

  • Publication number: 20190247538
    Abstract: Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.

The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.

  • Patent number: 9889284
    Abstract: Silver and/or zinc ion releasing implants, systems and method of operating, inserting and activating/inactivating them are described. In some variations the implant is configured as a bone implant that includes a bone-screw or intramedullary rod like body configured to receive a treatment cartridge having a plurality of ion-releasing members configured as an anode that can controllably engage with a catheter to turn galvanic release of ions on/off as desired. These devices may be configured to release silver ions (and/or zinc ions) above a predetermined level for a predetermined period of time and may maintain a concentration of ions over a relatively large volume of tissue. The ion-releasing members may be configured to reduce or prevent implant movement.
