Simpirica Spine, Inc.

The LimiFlex™ Dynamic Sagittal Tether™ was conceived by company co-founders Louie Fielding and Todd Alamin, MD, in the Stanford University Biodesign Innovation program. The idea behind LimiFlex was to provide spinal stabilization without compromising spinal function, in patients suffering from degenerative lumbar spinal disorders. The LimiFlex Dynamic Sagittal Tether is a new potential alternative to spinal fusion for patients receiving surgical decompression for grade 1 lumbar degenerative spondylolisthesis with spinal stenosis. LimiFlex is designed to restore natural segmental motion and stability after lumbar decompression by augmenting the posterior tension band. LimiFlex uses a novel design that works with the body’s natural anatomy to provide the incremental stability needed by maintaining lordosis and encouraging facet engagement. Unlike interspinous spacers, LimiFlex only engages when a patient bends forward, which avoids delivering excess force and stress on the spinous processes with each step. LimiFlex was designed to act as a ligament to augment the natural anatomy after a thorough decompression for the stenosis. At Empirical Spine we believe it’s time to create a new standard of care in spine surgery that works in parallel with the natural structures of the spine to restore functionality and optimize quality of life.
