Patent number: 11752004Abstract: A system configured to increase height of a vertebral body. An implant includes plates each defining a bearing surface configured to be moved away from one another to expand the implant within the vertebral body. Supports are each coupled to one of the plates and include a reduced thickness portion defining a material web configured to plastically deform during expansion of the implant. The system includes an implant carrier with which an end element of the implant is removably coupled, and a rod configured to be translated relative to the implant carrier to cause expansion of the implant. An opposed portion may be coupled to the supports and configured to receive a longitudinal force to be moved relative to the end element. Second supports may be each coupled to the end element and one of the plates. Each of the second supports may plastically deform during expansion of the implant.Type: GrantFiled: October 15, 2020Date of Patent: September 12, 2023Assignee: Stryker European Operations LimitedInventors: Jean-François Oglaza, Christian Renaud, Alain Leonard, Gildas Huet

Patent number: 5757473Abstract: An optical strain sensor for measuring microdeformations of a surface with a resolution of at least 0.2 microns. The sensor comprises at least one camera for taking photographs of areas of the surface, the photographs being separated by a known fixed distance from one another before deformation has occurred. Templates are selected on the photographs taken before deformation, relocalized on photographs taken after deformation of the surface, and the deformation is derived from the computation of the difference in distances between the templates before and after deformation has occurred.Type: GrantFiled: November 13, 1996Date of Patent: May 26, 1998Assignee: Noranda, Inc.Inventors: Harald Kanduth, Denis Jacob, Christian Renaud, Michel Cantin, Alain Coulombe
