When used together, the PIPELINE, CONCORDE and VIPER Systems provide less invasive access to the spine, controlled placement of an intervertebral spacer, and control during pedicle screw fixation. Each system was specifically designed to enhance a different aspect of minimally invasive spinal fusion surgery. The PIPELINE Access System is a set of retraction ports and instruments. The CONCORDE Implant and Instrument System is designed for a minimally invasive TLIF approach. The VIPER System simplifies percutaneous pedicle screw and rod placement while minimizing the muscle trauma and the number and size of incisions required. The VIPER Rod Holder allows the surgeon to easily guide the rod inside the screw heads without additional incisions.
