No
The description focuses on a physical implant (bar and stabilizer) and its material properties and design. While a CT scan is used for pre-shaping, there is no mention of AI/ML being used in this process or in the device's function.
Yes
The device is implanted to correct a physical deformity (Pectus Excavatum and other chest wall deformities), which is a therapeutic intervention.
No
The device is a Pectus Support Bar and Stabilizer, intended for surgical procedures to repair chest wall deformities. It is an implantable device used during surgery, not for diagnosing a condition. The CT scan is used to pre-shape the bar, making it part of the surgical planning, not a diagnostic output of the device itself.
No
The device description clearly details physical hardware components (Pectus Pre-bent Support Bar and Pectus Titanium Support Bar Stabilizer) which are implanted in the patient.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The described device is a surgical implant (a support bar and stabilizer) used to physically repair a chest wall deformity (Pectus Excavatum). It is a physical device inserted into the body during a surgical procedure.
- Intended Use: The intended use is for "surgical procedures to repair Pectus Excavatum and other chest wall deformities." This is a therapeutic and structural repair, not a diagnostic test performed on a sample.
The device utilizes a CT scan for pre-shaping the bar, but the CT scan itself is the diagnostic tool providing imaging information. The device is the surgical instrument/implant used based on that information.

Device Description
Pectus Pre-bent Support Bar: A stainless steel or titanium bar, variable length from 7 to 17 inches, and 0.50 inches wide, with two holes and notches on both ends for sutures to secure the bar to the lateral chest wall. The bar is pre-shaped based on a CT Scan provided by the Surgeon specifically for a certain patient. The titanium bar is only used when the patient has a nickel allergy.
Pectus Titanium Support Bar Stabilizer: A titanium elongated plate with a dovetail slot in the center of the plate for the Pectus Bar to slide into. Two lips come up over the bar to secure the Pectus Bar within the slot of the stabilizer. The stabilizers have two holes on either side of the slot to suture the stabilizer to the lateral chest wall together with the support bar preventing lateral movement and flipping of the bar.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.
(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Device Name: Lorenz Pectus Support Bar System
Classification Name and Reference:
Plate, Fixation, Bone
87 HRS (CFR 888.3030)
Device Classification: Class II
Device Description: Pectus Pre-bent Support Bar: A stainless steel or titanium bar, variable length from 7 to 17 inches, and 0.50 inches wide, with two holes and notches on both ends for sutures to secure the bar to the lateral chest wall. The bar is pre-shaped based on a CT Scan provided by the Surgeon specifically for a certain patient. The titanium bar is only used when the patient has a nickel allergy.
Pectus Titanium Support Bar Stabilizer: A titanium elongated plate with a dovetail slot in the center of the plate for the Pectus Bar to slide into. Two lips come up over the bar to secure the Pectus Bar within the slot of the stabilizer. The stabilizers have two holes on either side of the slot to suture the stabilizer to the lateral chest wall together with the support bar preventing lateral movement and flipping of the bar.
Intended Use: This device is intended for use in surgical procedures to repair Pectus Excavatum and other chest wall deformities.
Materials: Stainless Steel or Titanium
Possible Adverse Effects:
-
- Metal sensitivity reactions or allergic reaction to the implant material.
-
- Pain, discomfort, or abnormal sensation due to the presence of the device.
-
- Surgical trauma; permanent or temporary nerve damage, permanent or temporary damage to heart, lungs, and other organs, body structures or tissues.
-
- Skin irritation, infection, and pneumothorax.
-
- Fracture, breakage, migration, or loosening of the implant.
-
- Inadequate or incomplete remodeling of the deformity or return of deformity, prior to or after removal of implant.
-
- Permanent injury or death.
Substantial Equivalence
The Pectus Pre-bent Support Bar made of either Stainless Steel or Titanium and the Pectus Titanium Support Bar Stabilizer is believed to be substantially equivalent in application and function to:
Lorenz Pectus Support Bar Stabilizer (K981789) Lorenz Pectus Support Bar (K972420)
Statement of Comparison of Technological Features
Both the predicate and the new (contained within this submission) devices consist of non absorbable material (stainless steel, titanium) listed in FDA's Biomaterials Compendium and list of FDA recognized standards. The metallic materials and the intended use are technically equivalent. The modified devices are being added to:
- address the nickel sensitivity of some patients 一 and
-
- to address surgeon preference of receiving the Pectus Support Bar pre-bent.
Conclusions: The use of the modified devices and the predicate Pectus Support Bar and Stabilizer are substantially similar.

Dear Ms. Reed:
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 (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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
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); good manufacturing practice requirements as set
