Intended Use
For use during surgical procedures to repair Pectus Excavatum and other sternal deformities with Lorenz Pectus Support Bar 510(k) number K972420 when additional stabilization is necessary.
Device Description
Stabilizer for a single bar: Two designs will be offered for stabilization of a single bar. One design will be an elongated plate and one will be a triangular plate which will be added at the ends of the Lorenz Pectus Support Bar. The stabilizers have 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 stabilizers bave 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. Stabilizer for two bars: The design is a triangular plate with two dovetail slots to slide the Lorenz Pectus Support Bars into. Two lips will come up over the bars to secure the pectus bars within the stabilizer. The stabilizer will have a single hole to suture the stabilizer and the bars to the lateral chest wall preventing lateral movement and flipping of the bar.
More Information

No
The device description focuses on mechanical stabilization components and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML. The "Mentions AI, DNN, or ML" and "Description of the training set..." sections are also marked as "Not Found".

No
The device is described as a "stabilizer" for a pectus support bar, which is used during surgical procedures to repair sternal deformities. Its function is to prevent lateral movement and flipping of the support bar, making it an accessory or adjunctive device to a therapeutic device (the support bar itself), rather than a therapeutic device in its own right.

No

This device is a stabilizer used to secure a Pectus Support Bar during surgical repair of sternal deformities, which is a therapeutic function, not a diagnostic one.

No

The device description explicitly details physical components (elongated plate, triangular plate, dovetail slot, lips, holes) that are added to a surgical bar, indicating it is a hardware device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for surgical procedures to repair sternal deformities. This is a surgical implant/device used directly on the patient's body.
  • Device Description: The description details a physical device (stabilizer plates) designed to be implanted and attached to a pectus bar and the chest wall.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.

IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (inside the body) during surgery.

§ 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.

Summary of Safety and Effectiveness

Device Modification Name: Lorenz Pectus Support Bar Stabilizer

Name of previously cleared 510(k): Lorenz Pectus Support Bar - 510(k) K972420

Classification Name and Reference: Plate, Fixation, Bone 87 HRS (CFR 888.3030)

Intended use:

For use during surgical procedures to repair Pectus Excavatum and other sternal deformities with Lorenz Pectus Support Bar 510(k) number K972420 when additional stabilization is necessary.

Device Modification Description:

Stabilizer for a single bar: Two designs will be offered for stabilization of a single bar. One design will be an elongated plate and one will be a triangular plate which will be added at the ends of the Lorenz Pectus Support Bar. The stabilizers have 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 stabilizers bave 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.

Stabilizer for two bars: The design is a triangular plate with two dovetail slots to slide the Lorenz Pectus Support Bars into. Two lips will come up over the bars to secure the pectus bars within the stabilizer. The stabilizer will have a single hole to suture the stabilizer and the bars to the lateral chest wall preventing lateral movement and flipping of the bar.

Potential Risks:

The potential risks associated with the stabilizer used in conjunction with the support bar are the same as with the pectus support bar alone and any long-term, metallic implant. These include but are not limited to the following;

  • 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, proor to or after removal of implant.
