摘要： An expandable intervertebral implant includes a first endplate and a second endplate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second endplates together. The first and second wedge members configured to translate along an actuation member housed between the first and second endplates to cause the implant to expand from a first collapsed configuration into a second expanded configuration. The actuation member has a first threaded section spaced apart from a second threaded section where the first and second threaded sections are at an angle with each other. Between the first and second threaded sections on the actuation member there is a section that permits the first and second threaded sections to rotate in the same rotational direction. The actuation member is configured to move the first and second wedge members from the first collapsed configuration into the second expanded configuration so that the first and second endplates separate from each other to contact and engage the endplates of the adjacent vertebral bodies.

摘要： An insertion instrument is configured to attach and secure to an expandable implant. The insertion instrument includes a securement member that is configured to be secured to the implant both when the implant is in a collapsed configuration and when the implant is in an expanded configuration. The insertion instrument further includes a drive member that is configured to actuate the implant to the expanded configuration.
