  • Patent number: 6942697
    Abstract: The pair of lumbar interbody implants is designed to be pushed laterally in a space between adjacent vertebrae for replacing the disc between these vertebrae. Each implant comprises a first and a second saggital wall and an anterior wall at one end and a posterior wall at the other end. The two implants are asymmetric to each other and are therefore more appropriate for the transforaminal lumbar interbody fusion. Preferably a first implant has a first saggital wall with an outer surface that is curved and a second saggital wall that is essentially plane.
    Type: Grant

  • Patent number: 6666889
    Abstract: A lumbar intersomatic implant for insertion into the discal space between two adjacent vertebrae for reestablishing the anatomical intervertebral space, the implant being in the form of a generally rectangular cage having two sagittal walls interconnected by at least an anterior transverse wall and a posterior transverse wall, the walls defining between them an open volume for filling with bone. An “outer” one of the sagittal walls of the implant presents a top rim and a bottom rim each shaped to present at least one retention edge extending substantially in the sagittal plane, making insertion via a posterior path possible, and an outer face arranged to present a penetration assisting shape enabling the cage to be offset transversely to a locking position in the discal space, which position is obtained by the retention edge preventing the cage from being reversed transversely.

  • Patent number: 5180393
    Abstract: An artificial ligament for the spine is fixed by pedicle screws on two vertebrae of the spinal column and has first and second hollow eyelets, of general diabolo shape, each one including a concave seat intended to receive the head of the fixation screw; a body haivng a narrowed area; a convex hump complementing the concave seat and intended to be directed towards the vertebrae. The artificial ligament itself is made of a flexible textile material having a longitudinal primary winding arranged in figure eight formation between the narrowed areas of two successive eyelets and a transverse secondary winding arranged in contiguous spirals around the primary winding.
