  • Patent number: 8540721
    Abstract: Methods and apparatus for inserting an implant into an intervertebral cavity between adjacent vertebral bodies provide for: adjust an initial height between inner surfaces of respective first and second ramps of an inserter; simultaneously sliding first and second ramps of the inserter, and the implant, proximally, toward distal ends of the first and second ramps, such that the vertebral contact surfaces of the respective first and second ramps separate and distract the vertebral bodies and receive the implant into the intervertebral space with no compressive loading, while holding an initial angle between the ramps substantially constant; reversing the sliding of the first and second ramps to permit the vertebral bodies to compressively load the implant, again while holding the initial angle therebetween substantially constant; and withdrawing the distal ends of the first and second ramps from the intervertebral space.

  • Patent number: 8500749
    Abstract: An instrument for inserting an implant between vertebrae includes an upper and a lower ramp each having a respective proximal and a distal end. A bracket assembly is coupled to the upper and lower ramps at the proximal ends. The bracket assembly biases the upper and lower ramps closed at the distal end. A drive member has a longitudinal axis and a screw thread thereon. The drive member is disposed between the upper and lower ramps and extends through a passage in the bracket assembly. An adjustable spreader is operably coupled to the drive member and movable between the upper and lower ramps along the longitudinal axis by rotation of the drive member. The adjustable spreader separates the upper ramp from the lower ramp during forwardly movement along the longitudinal axis. An implant holder is coupled to the adjustable spreader.
