Patent number: 11583419Abstract: A spine implant for a TLIF surgical procedure is configured to be guided into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a pivoting post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of an opening in and end of the cage and a groove in the pivot post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.Type: GrantFiled: September 3, 2021Date of Patent: February 21, 2023Assignee: LifeSpine, Inc.Inventors: Gregory Palagi, Eugene Shoshtaev, Madeline C. Wolters, David T. Mehl, Daniel P. Predick, Casey Rice

Patent number: 11350968Abstract: A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.Type: GrantFiled: February 13, 2020Date of Patent: June 7, 2022Assignee: LIFE SPINE, INC.Inventors: Forrest Samuel, Gregory Palagi

Patent number: 11284923Abstract: A spine fixation assembly has a polyaxial spine screw rod holder for a first spine rod and a second rod holder for a second spine rod, the second rod holder is linked to the polyaxial spine screw rod holder via a connector, the connector extending radially outward from the polyaxial spine screw rod holder such that the second rod holder is spatially separated from and offset relative to the polyaxial spine screw rod holder. The polyaxial spine screw rod holder defines a first rod seat that holds the first spine rod. The first spine rod has a first longitudinal axis. The second rod holder defines a second rod seat that holds a second spine rod. The second rod has a second longitudinal axis. The second rod holder is oriented relative to the polyaxial spine screw rod holder by the connector at an offset (angle).Type: GrantFiled: January 22, 2020Date of Patent: March 29, 2022Assignee: Life Spine, Inc.Inventors: Gregory Palagi, Ra'Kerry Rahman, James M.

Patent number: 11135065Abstract: A spinal interbody implant is fabricated using 3-D printing to provide an engineered structure of one or more porous, permeable, or non-solid portions with or without one or more solid, dense, or micro-dense portions. The porous, permeable, or non-solid structure can be a mesh, lattice, web, weave, honeycomb, simple cubic, tetrahedral, diamond, or otherwise with the number and size of its pores, holes, perforations, or openings, as well as the distance or thickness between them, can vary accordingly. Some portions of the porous, permeable, or non-solid structure(s) may have porosities and/or thicknesses different than other portions. The solid, dense, or micro-dense structure may be constant throughout the body of the implant or may be a range of densities throughout the body of the implant. Alternately, one or more portions of the implant may have a range of densities throughout its body ranging from solid to a maximum porosity.Type: GrantFiled: March 9, 2018Date of Patent: October 5, 2021Assignee: LIFE SPINE, INC.Inventors: Richard M.

Patent number: 10973553Abstract: A modular pedicle screw assembly has a multi-part cam lock structure for fixing a threaded shank to a head subassembly. A modular pedicle screw assembly provides capture and release of a spherical end of a threaded shank by a head through rotation of closures radially disposed in an internal chamber of the head. Geometry of the closures cooperate with geometry of the internal chamber, providing a selective cam action between the closures and the internal chamber to increase and decrease size of an opening formed by the closures. Closure rotation produces an open state where the spherical end of the threaded shank can pass through the closures, releasing the spherical end of the threaded shank from the head, and a closed state where the spherical end of the threaded shank cannot pass through the closures thereby capturing the spherical end of the threaded shank in the head.Type: GrantFiled: April 2, 2019Date of Patent: April 13, 2021Assignee: LIFE SPINE, INC.Inventors: Forrest Samuel, Gregory Palagi

Patent number: 10675157Abstract: A lumbar spine implant has a body with bone screw bores that angle from a metal faceplate situated at an end of the body, the bone screw bores sized such that the bone screw bores become threaded during introduction of a bone screw thereby providing a locking mechanism to prevent the bone screw from backing out. The faceplate also provides a pocket for each bone screw that prevents the bone screw head from advancing through the implant body. The lumbar spine implant has four bone screw bores, two of which extend from the faceplate to the upper side of the body, and two of which extend from the faceplate to the lower side of the body. More or less bone screw bores may be provided. Preferably, but not necessarily, the direction of the bone screw bores are staggered from one lateral side to another lateral side of the body.Type: GrantFiled: March 26, 2018Date of Patent: June 9, 2020Assignee: Life Spine, Inc.Inventors: Paul C.

Patent number: 10568673Abstract: A laminar fixation system includes a laminar fixation implant and a laminar fixation implant tensioning tool for use with laminar fixation tape for retaining a spine rod relative to a vertebra of the spine. The laminar fixation implant has a hook at one end thereof that defines an arcuate pocket for holding a spine rod, a threaded angled bore with a set screw that contacts and fixes a spine rod received in the arcuate pocket, a passage extending through the hook for receiving laminar fixation tape, and a fixation plate disposed in a sidewall of the arcuate pocket of the hook and abutting the passage, whereby pressure exerted on the fixation plate by the spine rod presses against and fixes the laminar fixation tape in the passage relative to the laminar fixation implant.Type: GrantFiled: April 10, 2018Date of Patent: February 25, 2020Assignee: LifeSpine, Inc.Inventors: Gregory Palagi, Michael S.
