Patent number: 10314620Abstract: A vertebral support device (1) is disclosed, which in various embodiments comprises at least two osseous anchoring implants (2), each designed to be anchored to a vertebra, and at least one linking element (3) fixed to the osseous anchoring implants (2) by fasteners (20) that maintain a fixed angle between the longitudinal axis (L) of the linking element (3) passing through rigid elements (34) of the linking element (3) and the insertion axis (DV) of the implants (2). The linking element (3) includes at least one elastic dampening element (31) that that allows the implant-bearing vertebrae some freedom of movement. The dampening element (31) accommodates the stresses imposed on the linking element (3) during movement of the vertebrae and tends to return the support device (1) to its normal configuration.Type: GrantFiled: August 15, 2017Date of Patent: June 11, 2019Assignee: LDR MedicalInventors: Paul Cho, Reginald Davis, Gregory Hoffman, Alan McGee, John Williams, Arnold M.

Patent number: 10245157Abstract: Anchoring devices for rachidian implants, implants, surgical instruments, and surgical systems and methods are disclosed. In some embodiments, an anchor comprises a stiff plate with a longitudinal axis, configured for penetration of its anterior end into a vertebral surface while its posterior end remains engaged with the implant. An implant may include a locking mechanism for the anchor. An anchor may include an abutment configured to abut a complementary abutment of an implant. In some configurations, inserting an anchor in a passage of an implant may displace a locking mechanism, which may resile and lock the anchor in the implant with complementary abutments of the anchor and implant abutting.Type: GrantFiled: March 27, 2018Date of Patent: April 2, 2019Assignee: LDR MedicalInventors: Hervé Chataigner, Craig Chebuhar, Pierre Bernard, Hervé Dinville, Emmanuel Bougere
