Publication number: 20240122625Abstract: A tensegrity external fixation system utilizes a tensegrity external fixator having a compression portion and a tension portion that create a force to distract bone. A tensegrity external fixator has a compressor assembly with an extension that is compresses by a tension element, such as a tension band. In an embodiment, the tension band is coupled with a bone via a stud that is attached to the bone. The tension band may extend through a stud retainer, such as a loop coupled with the stud. A single extension may be used and compressed to cause the extension to bow between a tension band or wires. In an exemplary embodiment, a compressor assembly has a compression element that is compressed by the one or more extensions. Two extensions may extend from a compressor coupling having a compression element and manipulation of the extensions may place the compression element in compression.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventor: Brent Schultz

Publication number: 20240122626Abstract: A fixation device includes a body having a first axial end and a second axial end defining a longitudinal axis. The body has a longitudinal bore therein, and a longitudinal slot in a first side of the body extending laterally to the bore. A mounting bracket is connected to the first axial end at a second side opposite the slot and extends outward therefrom. The mounting bracket is configured to be mounted to a first structure. A support member is retained in the bore and is configured to move longitudinally in the bore. The support member protrudes outward from the first side of the body to support a second structure a longitudinal distance from the first structure. A lead screw engages a threaded hole in the base whereby rotation of the lead screw moves the support member to adjust the longitudinal distance between the first and second structures.Type: ApplicationFiled: October 18, 2023Publication date: April 18, 2024Applicant: Rensselaer Polytechnic InstituteInventors: Luke Douglas Kaiser, Max Phoenix, John Lurie, Akanksha Singh, Mousa Hamad

Publication number: 20240122627Abstract: A spinal bone fastener assembly (1) is proposed for stabilising the posterior spine. The assembly (1) comprises a pedicle screw (10), a rod receiving head (60), an insert (70) and a setscrew (80) intended to rigidly fixate a spinal rod (90). The pedicle screw (10) is longitudinally divided into a shaft tip section, a first shaft middle section, a second shaft middle section, a shaft transition section, a neck section, and a head section (21). The pedicle screw (10) comprises at least two parallel bone threads, namely a first bone thread and a second bone thread, both following a helical path around the shaft axis. The first and second bone threads at least in the second shaft middle section define a first substantially cylindrical thread section, and a second substantially cylindrical thread section, respectively. The first and second bone threads have different crest heights and/or outer thread diameters at least in the second shaft middle section.Type: ApplicationFiled: December 9, 2021Publication date: April 18, 2024Applicants: INTEGRUM MEDICAL AGInventors: Harald KINZNER, Rinaldo DE AGOSTINO, Tom OVERES
