Patent number: 10478310Abstract: This disclosure provides various vertebral implants, devices for attaching a vertebral implant and implantation instrumentations. In some embodiments, the implant includes a first body and a second body, each having a face with shapes and dimensions mating that of the other body and forming mutual fitting means, thus allowing assembly of the bodies by sliding along a sliding axis. In some embodiments, a locking means is retained in one of the bodies and an abutment portion may move from an open position allowing sliding for the assembling of the bodies to a closed position locking the bodies in assembly by the contact between the abutment portion, by contact with an abutment of the other body, the abutment being oriented angularly to the sliding axis and the abutment portion passing from the open position to the closed position elastically by flexure or torsion.Type: GrantFiled: March 4, 2015Date of Patent: November 19, 2019Assignee: LDR Medical, S.A.S.Inventors: Marc Ameil, Daniel D.
