Indications for Use
The T2 Stratosphere™ Expandable Corpectomy System is a vertebral body replacement device intended for use in the thoracic and lumbar spine (TI-L5) and cervical spine (C2-C7). The T2 Stratosphere™ Expandable Corpectomy System is intended for use in skeletally mature patients. When used in the cervical spine, the T2 Stratosphere™ Expandable Corpectorny System is used to replace a collapsed, damaged, or unstable vertebral body caused by tumor, trauma (i.e. fracture), or osteomyelitis, or for reconstruction following corpectomy performed to achieve decompression of the spinal cord and neural tissues in cervical degenerative disorders. When used in the cervical spine. the T2 Stratosphere™ Expandable Corpectomy System may not be used with optional modular end caps. When used in the cervical spine at single or two levels, the T2 Stratosphere™ Expandable Corpectomy System is intended to be used with supplemental fixation for use in the cervical spine. When used at more than two levels, supplemental fixation should include posterior fixation cleared for use in the cervical spine. When used in the thoracic and lumbar spine, the T2 Stratosphere™ Expandable Corpectomy System is used to replace a collabsed, damaged, or unstable vertebral body due to tumor or trauma (i.e. fracture). The T2 Stratoshere™ Expandable Corpectorny centerpiece may be used with or without optional modular end caps which accommodate individual anatomic requirements. The device is to be used with supplemental fixation cleared for use in the thoracic and lumbar spine. When used in the cervical spine, the T2 Stratosphere™ Expandable Corpectomy System is intended for use with autograft or allogenic bone graft comprised of cancellous bone graft as an adjunct to fusion. When used in the thoracic and lumbar spine, the 72 Stratosphere™ Expandable Corpectomy System is intended for use with autograft or allograft as an adjunct to fusion. The T2 Stratosphere™ Expandable Corpectory System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time in patients with advanced stage tumors involving the cervical and/or thoracolumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion.
Device Story
Adjustable vertebral body replacement device; titanium alloy construction; self-adjusting end caps provide 0-8° continuous angulation. Implanted between vertebral bodies via lateral, oblique, posterior, or anterior surgical approaches; minimally invasive or open techniques. Used with autograft/allograft as adjunct to fusion; restores spinal column integrity in advanced tumor patients where fusion is not feasible. Requires supplemental fixation. Intended for use by surgeons in clinical/OR settings. Benefits include spinal stabilization and correction of collapsed/unstable vertebral bodies.
Clinical Evidence
Bench testing only. Biocompatibility evaluated per ISO 10993. Bacterial endotoxin testing (LAL) performed to verify compliance with 20 EU/device limit per ANSI/AAMI ST72 and USP <161>. Mechanical performance data leveraged from predicate devices (K173125) tested per ASTM F2077 and ASTM Draft Standard F-04.25.02.02.
Technological Characteristics
Material: Titanium alloy (Ti6Al4V) per ASTM F136. Design: Expandable centerpiece with modular end caps (0-8° angulation). Sterilization: Provided sterile. Connectivity: None. Software: None.
Indications for Use
Indicated for skeletally mature patients requiring vertebral body replacement in the cervical (C2-C7) or thoracolumbar (T1-L5) spine due to tumor, trauma (fracture), or osteomyelitis; also for cervical reconstruction following corpectomy for degenerative disorders. Contraindicated for stand-alone use; requires supplemental fixation.
Regulatory Classification
Identification
A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

| Comparison of<br>Technological<br>Characteristics with<br>the Predicate<br>Devices | T2 STRATOSPHERE™ Expandable Corpectomy System Implants<br>The subject T2 STRATOSPHERE™ Expandable Corpectomy System Implants<br>have identical: indications for use, intended use, material (Titanium Alloy Per<br>ASTM F136), levels of attachment, fundamental scientific technology and<br>similar design as the T2 STRATOSPHERE™ Expandable Corpectomy devices<br>previously cleared by the FDA in K181328, S.E. 09/19/2018 and K173125, S.E.<br>12/20/2017. The subject devices are identical to the predicates cleared within<br>the T2 STRATOSPHERE™ Expandable Corpectomy system in terms of<br>material, intended use, level of attachment, size range, material and<br>fundamental scientific technology. The subject devices are very similar in<br>design to the predicate devices and the only technological difference between<br>the subject and predicate T2 Stratosphere™ Expandable Corpectomy System<br>implants is the subject T2 STRATOSPHERE™ devices are provided sterile |
| | while the predicate T2 STRATOSPHERE™ devices are provided non-sterile.<br>Additionally, the subject T2 STRATOSPHERE™ Expandable Corpectomy<br>System Implants are provided sterile and are identical to that of Predicate 3<br>cleared by the FDA in K071033. S.E. 08/14/2007. The sterilization method used<br>for the subject devices is identical to the sterilization method used for Predicate<br>3T2 XVBRT™ System (K071033. S.E. 08/14/2007). |
| Performance Data | The following information is provided in support of substantial equivalence. |
| | <b>Biocompatibility</b><br>The subject, T2 STRATOSPHERE™ Expandable Corpectomy System Implants<br>are permanent implants(>30days) and will be classified as body contacting<br>devices according to FDA's Draft Guidance for Industry and FDA Staff "Use of<br>International Standard ISO-10993, Biological Evaluation of Medical Devices<br>Part 1: Evaluation and Testing within risk management process." The subject<br>implants are manufactured from identical materials as the predicate devices<br>(K181328, S.E. 08/19/2018 and K173125, S.E. 12/20/2017) in accordance with<br>the following standards:<br>ASTM F136, Standard Specification for Wrought Titanium-6<br>Aluminum-4 Vanadium ELI Alloy for Surgical Implant Applications The manufacturing processes performed on the subject implants are standard<br>industry practices and are identical to the predicates 1 and 2. |
| | <b>Mechanical Testing</b><br>The subject implants are the same as the predicate implants in terms of<br>material, sizes and intended use. Mechanical testing for the predicate implants<br>were tested in accordance with the following standards: |
| | ASTM F2077, Test Methods For Intervertebral Body Fusion Devices ASTM Draft Standard F-04.25.02.02, Static Push-out Test Method for Intervertebral Body Fusion Devices Staff |
| | Therefore, non-clinical mechanical testing was not performed on the Subject<br>sterile implants. Detailed Mechanical Testing information is provided in the<br>Predicate 2 (K173125, S.E 12/20/2017) submission. The subject devices do not<br>introduce a new worst case, hence Medtronic believes that testing conducted on<br>the predicate implants satisfies testing requirements for the subject devices. The<br>subject devices do not introduce a new worst case scenario and are substantially<br>equivalent to the predicate devices. |
| Pyrogenicity | |
| | The bacterial endotoxin test, also known as Limulus amebocyte lysate (LAL)<br>test, was performed utilizing worst case subject implants to verify that the<br>subject implants meet the 20 endotoxin units (EU)/device pyrogen limit<br>specification. Testing was successfully performed, and it was confirmed that the |
| | subject implants meet the 20 EU/device testing limit for general medical devices<br>that are implanted as outlined in ANSI/AAMI ST72, Bacterial endotoxins – Test |
| | methods, routine monitoring, and alternatives to batch testing and USP <161>, |
