Patent number: 11684467Abstract: The present invention provides an anchor system for musculoskeletal applications, e.g., for anchoring tendons or ligaments to bone or anchoring two or more bone sections. The anchor system comprises a substantially solid pre-manufactured distal portion (i.e., anchor component) and a settable, biodegradable composite. The biodegradable composite is flowable at the time of delivery and is introduced into the fixation site before or after the anchor component. Both the anchor component and the biodegradable composite may be manufactured from citrate-based polymers.Type: GrantFiled: November 7, 2017Date of Patent: June 27, 2023Assignee: Acuitive Technologies, Inc.Inventors: Alex Khowaylo, Michael P. McCarthy, Minh-Tuan Richard Tran, Rui J. Ferreira

Patent number: 11285241Abstract: Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.Type: GrantFiled: July 9, 2019Date of Patent: March 29, 2022Assignee: Tyber Medical, LLCInventors: Jeffrey Tyber, Rui J.

Patent number: 11234741Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as through a fixation procedure. A system for a percutaneous procedure is provided. The system can include a bone fastener including a receiver. The system can include a device having a first end, a second end and a middle portion. The first end, middle portion and second end can be disposed along a longitudinal axis, and the second end can be connected to the receiver. The middle portion can have a pair of deformable leg members extending between the first and second ends. The leg members can define a channel having a width. The leg members can be selectively movable between a retracted state and an expanded state with the width of the channel greater in the expanded state than in the retracted state.Type: GrantFiled: July 31, 2019Date of Patent: February 1, 2022Assignee: Zimmer Biomet Spine, Inc.Inventors: Rui J.

Patent number: 10980589Abstract: An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.Type: GrantFiled: March 20, 2019Date of Patent: April 20, 2021Assignee: Zimmer Biomet Spine, Inc.Inventors: Anthony C.

Publication number: 20150138580Abstract: Methods and systems establish dynamic profiles for each of many document processing devices, based on current device connection specifications, current device drivers, current device capabilities, and current device workflow functions using a centralized connection device. These methods and systems provide device menu options from the centralized connection device to graphic user interfaces of the document processing devices. The device menu options provided from the centralized connection device displays the graphic user interfaces for the control of the document processing devices with the currently available workflows (that will be processed using a corresponding device and at least one other device of the document processing devices) and currently available management functions for the corresponding device and the other device(s) of the document processing devices. The “corresponding” device corresponds to the specific one of the graphic user interfaces receiving input to the device menu options.Type: ApplicationFiled: November 20, 2013Publication date: May 21, 2015Applicant: XEROX CORPORATIONInventors: Francis Kapo Tse, Rui J.
