Publication number: 20240091022Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.Type: ApplicationFiled: November 27, 2023Publication date: March 21, 2024Inventors: Collin Newman, Christian Karl Schultz, Steven Willis, Amir Ali Sharifi-Mehr, Oliver Buchert, Christopher P. Bell, Andrew Edward Ehlers, Anna Reza, Marc Gilles Long, Joseph Henry Robinson

Patent number: 11856027Abstract: A secure communication system enabling secure transport of information is disclosed. The system comprises a secure network with one or more packet processing units connected by links through an internal communication system. The secure network transports packets of information between credentialed and authenticated agents. Each packet is associated with a visa issued by a visa service. The visa specifies the procedures governing the processing of the packet by the packet processing units as it is transported along a compliant flow, between agents thorough the network, according to a set of policies specified in a network configuration. Packet processing units include docks and forwarders. Adaptors serving the agents communicate with the network through tie-ins to docks. The system also includes and admin service, accessible to one more admins, that facilitates configuration and management of the network.Type: GrantFiled: November 6, 2020Date of Patent: December 26, 2023Assignee: APPLIED INVENTION, LLCInventors: W. Daniel Hillis, David C. Douglas, Mathias Kolehmainen, Steven Willis, Frank Kastenholz, Michael Dubno

Publication number: 20230404773Abstract: Disclosed herein are embodiments of a spinal implant having structures that incorporate a solid material and a porous material. The solid material provides the implant with an outer shell for structural integrity while the porous material, distributed within an interior of the implant as a lattice structure for example, promotes visibility of the implant in radiological imaging, promotes bony ingrowth and cell attachment and improves wicking.Type: ApplicationFiled: October 1, 2021Publication date: December 21, 2023Inventors: Jason Noel Gantick, Ailon Haileyesus, Joseph Michael Meyer, Eleftherios Louvis, Leonid Pavlovsky, Joseph Henry Robinson, Steven Willis

Publication number: 20230380983Abstract: A spinal interbody implant includes an outer shell, a fill material disposed within the outer shell and a plurality of tubes extending from a first outer surface of the implant to a second outer surface of the implant through the fill material. The fill material is more porous than the outer shell and the plurality of tubes.Type: ApplicationFiled: October 13, 2021Publication date: November 30, 2023Inventors: Sean Corcoran, Keith Fava, Kenneth Dieselman, Jennifer Anne Moore, Amir Ali Sharifi-Mehr, Christopher P. Bell, Steven Willis, Russell Simms, Justyna Zielinska, Christian Karl Schultz, Clint Boyd, Eleftherios Louvis, Leonid Pavlovsky, Joseph Henry Robinson

Publication number: 20230285162Abstract: Disclosed herein is a spinal implant with a solid frame and a porous inner layer. The implant may have a cavity defined by the porous inner layer. The solid frame may have one or more ribs extending from a medial wall to a lateral wall. The thickness of the porous layer may vary relative the thickness of the solid frame at various locations. An inserter to place a spinal implant and a method to perform same are also disclosed.Type: ApplicationFiled: February 24, 2023Publication date: September 14, 2023Inventors: Bryan D. Milz, Thomas A. Alheidt, Jessica Centrangol, Christian Karl Schultz, Jason H. Steinke, Steven Willis, Robert Cipoletti, Charles L. Bush, JR., Brad Juchno

Publication number: 20230277731Abstract: Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.Type: ApplicationFiled: February 24, 2023Publication date: September 7, 2023Inventors: Bradley William Paddock, Amir Ali Sharifi-Mehr, Adam Laurance Wollowick, Oliver Buchert, Matthew B. Havener, Robert Cipoletti, Steven Willis, Marc Gilles Long

Publication number: 20230171228Abstract: Methods, devices, and system related to secure communication systems are disclosed. In one example aspect, a secure communication system enabling secure transport of information includes a secure network comprising one or more nodes communicatively coupled by an internal communication system and a set of policies. The secure network internally transports the information in the form of internal packets. Each of the internal packets is associated with a visa that references the policies. A node among said one or more nodes transmits an internal packet of said information only if allowed by said policies as referenced by said visa.Type: ApplicationFiled: January 27, 2023Publication date: June 1, 2023Inventors: W. Daniel Hillis, David C. Douglas, Mathias Kolehmainen, Steven Willis, Frank Kastenholz, Michael Dubno
