Patent number: 11969354Abstract: The invention relates to medical implants, including spinal implants and bone grafts, for fixation and integration with hard tissue. The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.Type: GrantFiled: August 12, 2021Date of Patent: April 30, 2024Assignee: LifeNet HealthInventors: Jingsong Chen, Dennis Phelps, Andy T. Pritchard, Nathan Kemper, Thomas Brewer

Publication number: 20240099856Abstract: A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Applicant: LifeNet HealthInventors: Mark Evans, Dennis Phelps, Jingsong Chen

Publication number: 20240076982Abstract: A downhole tool for connecting and releasing portions of a tool string includes a housing; an electronics assembly; an activation mechanism; a valve assembly and a set of retainer dogs to connect and release a neck of another tool. The downhole tool may also include one or more measurement sensors for measuring a parameter and transferring one or more measured parameter values to the surface of the well.Type: ApplicationFiled: November 8, 2023Publication date: March 7, 2024Applicant: GEODYNAMICS, INC.Inventors: Phil Phelps, John T. Hardesty, Dennis E. Roessler, Terrell Saltarelli

Publication number: 20240009352Abstract: The present invention provides demineralized bone fibers exhibiting optimal handling properties (e.g., high moldability and low elastic modulus) and biological activities (e.g., osteoinductivity) as well as non-demineralized bone fibers useful for preparing the demineralized bone fibers. A well-controlled demineralization process for preparing the demineralized bone of fibers is also provided. Products comprising the demineralized bone fibers and uses thereof are further provided.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Applicant: LifeNet HealthInventors: Silvia Chen, Grant Cleavenger, Dennis Phelps, Breanne Gjurich, Evans Wralstad, Austin Johnson, Alana Sampson, Adam Entsminger, Jingsong Chen

Patent number: 11253297Abstract: A pin made of cortical bone may be inserted into adjoining bones of a toe to align and secure the bones. The pin may have barbs to prevent migration of the pin. The pin may include a shoulder to further prevent migration of the pin from the bones, to increase the strength of the pin, and to increase the surface area between the bone pin and the host bone. The pin may further include flattened portions on its circumference to aide in rotating the pin during insertion. The pin may be treated to reduce brittleness.Type: GrantFiled: April 9, 2020Date of Patent: February 22, 2022Assignee: LIFENET HEALTHInventors: Jingsong Chen, Thomas Sander, Dennis Phelps, Andy Pritchard, Roberto Bracone
