  • Articulating transforaminal lumbar interbody fusion inserter device and associated method of use
    Patent number: 8398649
    Abstract: The present invention provides an articulating TLIF inserter device operable for placing, positioning, and inserting a spinal implant into an intervertebral space with minimum tissue disruption and maximum inline impaction forces, including: an elongate shaft having a proximal end, a distal end, and an axis; an ergonomic handle disposed at the proximal end of the elongate shaft; an articulating joint mechanism disposed at the distal end of the elongate shaft; and an inserter piece coupled to the articulating joint mechanism, wherein the inserter piece is operable for selectively retaining the spinal implant, and wherein the articulating joint mechanism is operable for selectively actuating the inserter piece between one or more substantially off-axis configurations and a substantially on-axis configuration with respect to the elongate shaft.
