Publication number: 20220296374Abstract: An implant assembly for a long bone is adapted to support an exo-prosthesis. The assembly includes a stem, a subdermal component and a percutaneous post. The stem has a proximal end that is adapted to be received in a surgically prepared medullary canal of the long bone, and a distal end having a surface that is adapted to promote bone ingrowth. The subdermal component includes a proximal portion that is adapted for attachment to the distal end of the stem, and a fixation surface that is adapted to promote soft tissue fixation. The percutaneous post has a proximal end that is adapted to be attached to the subdermal component.Type: ApplicationFiled: April 11, 2022Publication date: September 22, 2022Inventors: Kent N. Bachus, Sujee Jeyapalina, James Peter Beck, Roy Bloebaum, Jayant P. Agarwal, Joseph A. Longo, Erik Kubiak, Brian Mueller Holt

Patent number: 9668889Abstract: An implant system for securing a prosthesis to a selected bone of a subject including a stem and an abutment. The stem includes a porous region that promotes osseointegration of the selected bone following implantation of the stem. The abutment is secured to the stem and is configured for secure attachment to the prosthesis. The stem and the abutment include ultra-low friction and/or highly polished surfaces at select locations that inhibit bio-adhesion.Type: GrantFiled: June 6, 2012Date of Patent: June 6, 2017Assignee: University of Utah Research FoundationInventors: Brian Mueller Holt, Kent N.

Patent number: 9308103Abstract: The invention includes an osseointegrated mount and electrical connector, suitable for providing neural control and sensory feedback for an advanced prosthetic limb. The device provides a channel in which a lead wire from the peripheral nerve interface can travel from the electrical connector down the side of the device or within the device to limit potential sites of infection to a single transcutaneous breach. The channel allows for a silicone barrier to be installed between the internal and external components.Type: GrantFiled: August 20, 2014Date of Patent: April 12, 2016Inventors: David T. Kluger, David J. Warren, Gregory A. Clark, Kent N. Bachus

Publication number: 20130253664Abstract: An antimicrobial containment cap is provided for use in a bone anchored prosthesis mounting system of the type having an externally protruding fixator pin carried by implanted bone anchored mounting post, wherein the fixator pin accommodates removable attachment to an exoskeletal prosthesis such as a prosthetic limb or the like for an amputee. The containment cap, when mounted onto the fixator pin, is interposed between the prosthesis and soft tissue covering the end or stump of an amputated residual limb or the like. The containment cap carries and supports a selected antimicrobial or antibacterial agent in substantial contact with the soft stump tissue in a position closely overlying and substantially circumscribing the tissue interface with the externally protruding fixator pin to safeguard against infection. The containment cap is adapted for quick and easy periodic removal for cleaning and/or replenishment of the antimicrobial agent.Type: ApplicationFiled: May 20, 2013Publication date: September 26, 2013Applicant: UNIVERSITY OF UTAH RESEARCH FOUNDATIONInventors: Roy D. Bloebaum, Kent N. Bachus, Raymond E. Olsen

Publication number: 20120316657Abstract: A releasable attachment system is provided for use with a bone anchored post and related external prosthesis such as a prosthetic limb or the like, wherein the attachment system includes a safety release mechanism designed to release or break away when encountering an excess mechanical load. The bone anchored mounting post is implanted for direct affixation to patient bone, and carries or is connected to a fixator structure protruding through soft skin tissue and the like at the end or stump of an amputated limb for mechanical connection to the external prosthesis. The safety release mechanism accommodates substantially normal patient movement throughout a corresponding range of substantially normal mechanical loads, but releases in the presence of an excess load to prevent undesirable fracture failures.Type: ApplicationFiled: August 20, 2012Publication date: December 13, 2012Applicant: UNIVERSITY OF UTAH RESEARCH FOUNDATIONInventors: Kent N.
