Patent number: 11771801Abstract: 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.Type: GrantFiled: June 14, 2018Date of Patent: October 3, 2023Assignee: Evonik Operations GmbHInventors: Balaji Prabhu, Andrew Wood, Mahrokh Dadsetan, Andreas Karau, Harsh Patel, Marc Knebel, Suneel Bandi

Patent number: 10995188Abstract: The present invention relates to a thermoplastic composition that provides improved thermal aging stability. The thermoplastic composition includes a polyamide resin, glass fibers, tin(II) oxalate, and a functional additive. It has been found that a combination of a polyamide resin with tin(II) oxalate and a functional additive produces a superior product demonstrating greater thermal stability than the polyamide resin alone.Type: GrantFiled: October 26, 2017Date of Patent: May 4, 2021Assignee: Evonik Operations GmbHInventors: Suneel Bandi, Andreas Pawlik

Publication number: 20210046218Abstract: 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.Type: ApplicationFiled: February 1, 2019Publication date: February 18, 2021Applicant: Evonik Operations GmbHInventors: Balaji Prabhu, Andrew Wood, Mahrokh Dadsetan, Andreas Karau, Suneel Bandi, Kenneth Ross, Marc Knebel
