Publication number: 20240041445Abstract: A tissue retractor device within the scope of the present invention generally includes a frame, an actuating mechanism, and a plurality of blades. The actuating mechanism generally includes at least one cam that encourages automatic toe-out of the blades. The tissue retractor eliminates the need for bulky secondary blade mechanisms to prevent undesired blade deformation at the surgical site. The toe-out motion occurs simultaneously along with the opening of the blades. The present invention further provides for depth adjustment of the blades by means of an adjustable screw assembly.Type: ApplicationFiled: October 20, 2023Publication date: February 8, 2024Applicant: Alphatec Spine, Inc.Inventor: William Reimels

Publication number: 20230102897Abstract: The present disclosure relates to expandable interbodies that include superior and inferior shells and a control assembly positioned between and inside of the shells, the control assembly including nested cages operably connected to each other with an adjustment screw. Rotation of the adjustment screw translates the cages relative to each other, which in turn causes the shells to open or expand.Type: ApplicationFiled: December 5, 2022Publication date: March 30, 2023Applicant: Alphatec Spine, Inc.Inventors: William Reimels, Max C.

Publication number: 20230059243Abstract: A surgical screw configured to expand and prevent or minimize bone growth inside of the surgical screw is provided. Accordingly, the surgical screw is configured to increase the purchase of the surgical screw with respect to the bone, but also to be withdrawn from the bone without damaging the bone as a result of bone ingrowth. The surgical screw includes a center post with an inner bore and an outer sleeve concentric to the center post. An outer surface of the outer sleeve includes a thread to engage bone. The outer sleeve includes a cut pattern defining an expandable region configurable between a first state with a first radius measured from a longitudinal axis of the surgical screw to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface.Type: ApplicationFiled: October 24, 2022Publication date: February 23, 2023Applicant: Alphatec Spine, Inc.Inventor: William Reimels

Publication number: 20220273283Abstract: A system for interchangeable retractor blades includes a shell, a first retractor blade, and a second retractor blade. The shell includes a rigid proximal end configured to attach to a surgical retractor and an opening, a distal closed end, and a pliable portion including a pocket in communication with the opening and extending along a length of the shell to the distal closed end. The first retractor blade includes a first geometry received through the opening into the pocket and that shapes the pliable portion to configure the shell in a first configuration. The second retractor blade includes a second geometry received through the opening into the pocket and that shapes the pliable portion to configure the shell in a second configuration.Type: ApplicationFiled: May 19, 2022Publication date: September 1, 2022Applicant: Alphatec Spine, Inc.Inventor: William Reimels

Patent number: 10695115Abstract: An expandable screw includes generally a shaft, a head, and a cut pattern. The shaft includes a longitudinal axis, an outer surface including a thread to engage bone, and an expandable region configurable between a first state with a first radius measured from the longitudinal axis to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface. The cut pattern on the shaft permits at least partial nesting of a first portion of the expandable region within a second portion of the expandable region in the second state. The central lumen is closed by the abutment of a top portion of the second cut surface with the bottom portion of the first cut surface so as to form a closed structure or fluid seal preventing a bone ingrowth inside the central lumen.Type: GrantFiled: May 15, 2017Date of Patent: June 30, 2020Assignee: Alphatec Spine, Inc.Inventor: William Reimels

Patent number: 10299845Abstract: An orthopedic screw having a shaft and a thread ribbon is provided. The shaft includes a proximal driving end and a distal end. The thread ribbon extends around the shaft and including a base portion that is rigidly attached to the shaft and a flange portion that is resilient. The flange portion extends away from the shaft at a preset angle to form a preset outer thread diameter in a preset configuration. The flange portion extends away from the shaft at a second angle greater than the preset angle to form a second outer thread diameter greater than the preset outer thread diameter when the orthopedic screw is subjected to a pull out force.Type: GrantFiled: October 5, 2015Date of Patent: May 28, 2019Assignee: Alphatec Spine, Inc.Inventor: William Reimels
