  • Patent number: 11771801
    Abstract: The present invention comprises a polymer and/or polymer composite based sleeve to be fitted between an extended body, such the neck, trunnion, and/or stem of a hip implant, and a receiving body, such as a femoral head in a hip implant, that reduces wear, decreases toxic material from wear debris, enhances the mechanical connection of the extension and receiving body, reduces or eliminates impingement with receiving body, delocalize stress concentrations, and may also serve as a modifying junction between an extension and receiving body of unmatched size. The polymeric based sleeve presently disclosed comprises an inert and/or biologically favorable material which may be used in its virgin form or contain biocompatible additives. In order to best match patient and implant requirements, modifications may be made in the length, thickness, composition, as well as the presence of a taper, or lack thereof, in order to be compatible with existing devices.

  • Publication number: 20220326199
    Abstract: A method of unambiguous identification and authentication of products for the purpose of better recognition of product forgeries and controlling product piracy, including applying to/into the product an identification substance admixture which contains paramagnetic phases or identifying a product which contains an identification substance admixture containing paramagnetic phases and has an ESR fingerprint spectrum that permits unambiguous identification of the product. Such an ESR fingerprint spectrum is easily measurable, but can be copied or forged only with difficulty. The method relates to an individualizable “femto tag” for femto ledgers and forms an important interface for what are known as “Internet of Things” (IOT).

  • Publication number: 20210046218
    Abstract: The present invention comprises a polymeric based femoral and/or tibial component implant to be used in total knee replacement/arthroplasty procedures serving to provide increased wear resistance, enhanced physiological response at the bone/implant interface, and decreased stress-shielding. The implant can be made via additive manufacturing. The articulating surface of the implant may be implemented in without any additive or in a form containing an additive for improved tribological response. Further, the device disclosed herein contains an interfacial surface which is in contact with the native bone (i.e., bone/implant interface) which may exist in its pure form, containing a bioactive additive. The implant has a porous morphology on the bone/implant interface for improved biological response and improved fixation. The depth of the additives and the topographical morphology therein are controlled via techniques disclosed herein.
