Intended Use

The Invictus® Bands System consists of temporary implants for use in orthopedic surgery. The system is intended to provide temporary stabilization as a bone anchor during the development of solid bony fusion and aid in the repair of bone fractures. The indications for use include the following applications: • Spinal trauma surgery, used in sublaminar, interspinous, or facet wiring techniques; • Spinal reconstructive surgery, incorporated into constructs for the purpose of correction of spinal deformities such as idiopathic and neuromuscular scoliosis in patients 8 years of age and older, adult scoliosis, kyphosis, and spondylolisthesis; • Spinal degenerative surgery, as an adjunct to spinal fusions; • Use with a posterior spinal instrumentation construct when ligament augmentation is needed. The Invictus® Bands System may also be used in conjunction with other medical implants made of commercially pure titanium, titanium alloy, or cobalt chrome whenever “wiring” may help secure the attachment of other implants.

Device Story

Sublaminar fixation and ligament augmentation system; provides temporary bone stabilization during bony fusion; aids bone fracture repair. Components: PET bands, titanium alloy sleeves/connectors/set screws. Used in spinal surgery; operated by surgeons. Bands mate with 4.5–6.0 mm diameter rods; compatible with other titanium/cobalt chrome implants. Provides secure attachment via wiring techniques. Benefits: temporary stabilization for spinal deformity correction and fusion support.

Clinical Evidence

Bench testing only. Performance supported by ASTM F1798 static and dynamic band pull-through testing.

Technological Characteristics

Materials: PET braid (bands), Ti-6Al-4V ELI (ASTM F136) (sleeves/connectors/screws). Mechanical fixation via sublaminar bands and rod-locking connectors. Sterilization: Gamma irradiation (bands); steam sterilization (reusable instruments/non-sterile components).

Indications for Use

Indicated for patients 8 years of age and older requiring spinal stabilization or reconstruction. Applications include spinal trauma, spinal deformities (idiopathic/neuromuscular scoliosis, adult scoliosis, kyphosis, spondylolisthesis), spinal degenerative surgery as an adjunct to fusion, and ligament augmentation in posterior spinal constructs.

Regulatory Classification

Identification

A bone fixation cerclage is a device intended to be implanted that is made of alloys, such as cobalt-chromium-molybdenum, and that consists of a metallic ribbon or flat sheet or a wire. The device is wrapped around the shaft of a long bone, anchored to the bone with wire or screws, and used in the fixation of fractures.

Dear Griffin Riggs:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

Your device is also subject to, among other requirements, the Quality Management System Regulation (QMSR) (21 CFR Part 820), which includes, but is not limited to, ISO 13485 clause 7.3 (Design controls), ISO 13485 clause 8.3 (Nonconforming product), ISO 13485 clause 8.5.2 (Corrective action), and ISO 13485 clause 8.5.3 (Preventative action). Please note that regardless of whether a change requires premarket review, the QMSR requires device manufacturers to review and approve changes to device design and production (ISO 13485 clause 7.3 and ISO 13485 clause 7.5) and document changes and approvals in the Medical Device File (ISO 13485 clause 4.2.3).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the Quality Management System Regulation (QMSR) (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

and needle (leads) at the ends of the bands. The stainless steel leads are detached after insertion and are not intended to be implanted. Implants are available in a variety of sizes and can be rigidly locked into a variety of different configurations to suit the individual pathology and anatomical conditions of the patient.

The Invictus® Bands System connectors accept various rod diameters and are appropriate for use with any 4.5 – 5.0 mm and 5.5 – 6.0 mm diameter rod-based spinal fixation system cleared by FDA.

The bands are for single use and are provided terminally sterile via gamma irradiation. The sleeves, connectors, and set screws are for single use and are provided non-sterile to be steam sterilized by the end user. The system includes class I, reusable surgical instruments made of stainless steel and other materials and are provided non-sterile to be cleaned and steam sterilized by the end user.
