Publication number: 20240207485Abstract: The present disclosure provides citrate-based constructs for use in the repair of osteochondral defects. The constructs generally include: (i) a citrate component, (ii) a diol component, (iii) a polyol, and (iv) particulate inorganic material. The scaffold may take the form of a 50-90% porous scaffold and may form a polymer network. The scaffold may be soaked in a hyaluronic acid solution and may be freeze-dried to produce a porous construct within the pores of the scaffold. The scaffold may be biphasic, containing a porous section for subchondral bone regeneration and a citrate-based polymer hydrogel for cartilage regeneration. The scaffold may form an implant and the implant may include an inner porous core of a biphasic core-shell construct.Type: ApplicationFiled: December 27, 2023Publication date: June 27, 2024Applicant: Acuitive Technologies, Inc.Inventors: Minh-Tuan Richard Tran, Rui J. Ferreira, Michael P. McCarthy

Publication number: 20240156586Abstract: Graft tensioning systems and associated engagement assemblies are provided. The engagement assemblies include at least one engagement element or foot that is configured to engage with tissue adjacent or opposed to an implant-receiving opening. The engagement element(s) support stable interaction between the graft tensioning system and the anatomical target region, while reducing the potential for tissue bruising/trauma/contusions. The engagement elements may be interchangeably mounted relative to the graft tensioning device, e.g., intraoperatively, to permit a surgeon to select an engagement element offering desired properties for the specific procedure and/or anatomical properties of the patient.Type: ApplicationFiled: February 24, 2022Publication date: May 16, 2024Applicant: Acuitive Technologies, Inc.Inventors: Douglas William Gabel, Michael P. McCarthy, Rui J. Ferreira

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. Ferreira, Konstantin Caploon

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. DeFalco, Rawley Stanhope, Daniel C. Taylor, Rui J. Ferreira
