Publication number: 20240033100Abstract: Interbody implants may be formed by a product by process in which a first metallic frame component having an interconnected superior endplate and an interconnected inferior endplate are formed. In some embodiments, the endplates are interconnected by flexible struts and in others they are interconnected by translating struts. In various embodiments, a polymeric body may be infilled between the superior endplate and inferior endplate by a molding process, e.g., an injection molding process or an overmolding process. In various embodiments, the metallic frame may have a first compressive stiffness, the polymeric body may have a second compressive stiffness, and the first compressive stiffness of the metallic frame may be about 20% to about 80% of the second stiffness of the body. In various embodiments, a sum of the first compressive stiffness of the metallic frame and the second stiffness of the body is about 33,500 N/mm to about 11,500 N/mm.Type: ApplicationFiled: July 29, 2022Publication date: February 1, 2024Applicant: Warsaw Orthopedic, Inc.Inventors: Keith E.

Publication number: 20240008998Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.Type: ApplicationFiled: August 31, 2023Publication date: January 11, 2024Inventors: Charles Branch, Charles Fisher, Mladen Djurasovic, Marcel Dvorak, Sigurd Berven, Anthony J.

Patent number: 11857467Abstract: A surgical table includes a sagittal adjustment device for manipulating the position of a patient. The surgical table includes a base portion including an upper surface for spacing the sagittal adjustment device from the ground. The sagittal adjustment device includes a first support portion and a second support portion. The first and second support portions are supported by and moveable over the upper surface of the base portion. The first and second support portions each include an upper surface configured to support portions of the body of the patient thereon. One of the first and second support portions is pivotally attached to the base portion, and moveable between a first position and a second position. The pivotal movement between the first and second positions of the one of the first and second portions serves in repositioning the body of patient to manipulate the spine of the patient.Type: GrantFiled: January 29, 2021Date of Patent: January 2, 2024Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Jeffrey W.
