The Dyn-ALIF device is indicated for intervertebral body fusion of the spine in skeletally mature patients. The device is designed for use with autogenous bone graft to facilitate fusion. The Dyn-ALIF device is intended for use at either one level or two contiguous levels in the lumbar spine from L2 to S1 for the treatment of degenerative disc disease (DDD) with up to grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The lumbar device is to be used in patients who have had at least six months of non-operative treatment. The device is intended to be used with supplemental internal spinal fixation systems which are cleared by the FDA for use in the lumbar spine.

The Dyn-ALIF Anterolateral Intervertebral Body Fusion Device is an implantable device manufactured from titanium alloy which is available in the abutting plate interface dimension of 20mm x 30mm and a vertically expandable height ranging from 11mm anterior /9mm posterior to 15mm anterior/13mm posterior to suit the individual anatomic conditions of the patient. The assembled device consists of five components: two abutting plates with hollow threaded shafts, a central turnbuckle sleeve and two locking set screws. The components can be rigidly locked into a variety of heights, with each construct height measured for the individual case

- The Levante Intervertebral Pillar prosthesis is intended for use in the thoracolumbar spine (i.e., T1 to L5) to replace and to restore the height of a diseased vertebral body resected or excised for the treatment of tumor as well as to concomitantly facilitate anterior decompression of the spinal cord and neural tissues. Two contiguous vertebral bodies are the maximum number of bodies the device is intended to replace. The device is intended to be always implanted with adjunctive fixation. - To replace a vertebral body for tumor and to replace or restore the height of a vertebral body due to fracture; for example, burst or compression fractures - To facilitate anterior decompression of the spinal cord and neural structure - To facilitate the reduction of kyphotic deformities

This device is used to record and visually display movements of the eyes including nystagmus.

The VEMR™ Eye Movement Recorder is used to observe or record eye movements on a video monitor or video recording tape respectively. This device consists of: patient eye goggles, a video image splitter/power-supply, a video tape cassette recorder (VCR) video monitor console, and a remote control accessory. There is also a built-in microphone in the eye goggles to provide simultaneous voice recording's on a video recording tape. The patient eye goggles are an opaque, facially worn device fitted with tiny video cameras, infrared light emitting diodes (LED's), and a microphone. The diodes illuminate the eyes for video cameras that produce video signals. These signals are processed by the image processor that essentially allows for simultaneous viewing the video images of both eyes on the video screen. The microphone allows for recording of voices to help document events recorded on video tape. The remote control accessory provides remote control of the various functions (e.g. play, record etc.) on the VCR/video monitor console.
