Instrumentation and method for delivering an implant into a vertebral space

摘要

Instrumentation and method for delivering an implant into an intervertebral disc space, including a die member configured to transition the implant from an initial configuration to a deformed configuration having a reduced lateral profile suitable for insertion into the intervertebral disc space in a minimally invasive manner. In one embodiment, the die member includes an opening sized to receive the implant while in the initial configuration, and wherein relative displacement between the implant and the die member causes the implant to transition toward the reduced-profile deformed configuration. In a specific embodiment, the opening comprises an axial passage including a first portion having a rectangular cross-section corresponding to a substantially planar initial configuration of the implant, and a second portion having a circular cross-section corresponding to a substantially cylindrical deformed configuration of the implant.
