Wenzel Spine, Inc. CIE2-15-24-00 VariLift-L

The Wenzel Spine VariLift Lumbar Interbody Fusion Device is a self-tapping, expandable device with an interior sliding wedge and a posterior end cap. The VariLift-L is a grooved and fluted device with large graft windows positioned each of its four quadrants that provide bony contact with the endplates. VariLift-L is designed to be implanted bi-laterally via posterior (PLIF) approach or as a single device via a transverse (TLIF) approach. VariLift-L may be implanted with or without supplemental fixation and is intended for use with autograft to facilitate fusion. VariLift-L is indicated for intervertebral body fusion of the lumbar spine, from L2 to S1, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies.
