The summary describes a mechanical sternal closure system with screws and does not mention any software, algorithms, or AI/ML capabilities.
No
The device is described as a system for stabilizing and fixing fractures of the anterior chest wall, which is a structural or supportive function rather than a therapeutic one that treats specific diseases or conditions.
No
Explanation: The device is intended for the stabilization and fixation of fractures of the anterior chest wall following surgical procedures, which is a therapeutic and reconstructive function, not a diagnostic one.
No
The device description clearly states it is a system of physical screws made of titanium, intended for surgical implantation. This 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 clearly states the device is for the "stabilization and fixation of fractures of the anterior chest wall including Sternal fixation following Sternotomy and Sternal reconstructive surgical procedures." This describes a surgical implant used directly on the patient's body for structural support.
- Device Description: The description details a physical implant (screws) made of titanium, designed for surgical insertion.
- 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 treatment. IVDs are typically used in laboratories or point-of-care settings to analyze biological samples.
Therefore, the Lorenz Sternal Closure System is a surgical implant, not an In Vitro Diagnostic device.

§ 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 Sternal Closure System
Classification Name: Single/multiple component metallic bone fixation appliances and accessories
Device Product Code: 87HRS (21 CFR 888.3030) Class II
Intended Use: Lorenz Sternal Closure System is intended for use in the stabilization and fixation of fractures of the anterior chest wall including Sternal fixation following Sternotomy and Sternal reconstructive surgical procedures.
Description: The Lorenz Sternal Closure System 2.4 self drilling screws are 2.4 mm in diameter and the lengths may range up to 16mm. The tip of the screw is designed so that a predrilled hole is not required, but may be used.
Material: Titanium
The Lorenz Sternal Closure System will be marketed as non-sterile, single use devices. Sterility Information: Steam Sterilization recommendations are included in the package insert.
Substantial Equivalence: Walter Lorenz considers the Lorenz Sternal Closure System equivalent to Lorenz Sternal Closure System (K011076 and K033740), Lorenz Self Drilling Screw (K013954) and Lorenz 2.4 Self Drilling Screw (K032228).
Possible risks:
- Poor bone formation, Osteolysis, Osteomyelitis, inhibited revascularization, or infection can 1. cause loosening, bending, cracking or fracture of the device.
-
- Nonunion or delayed union, which may lead to breakage of the implant.
-
- Migration, bending, fracture or loosening of the implant.
-
- Metal sensitivity, or allergic reaction to a foreign body.
- খা Decrease in bone density due to stress shielding.
-
- Pain, discomfort, abnormal sensation, or palpability due to the presence of the device.
-
- Increased fibrous tissue response around the fracture site and/or the implant.
-
- Necrosis of bone.
-
- Inadequate healing.
- Selection of screws which are longer than the depth of the sternum may cause possible impingement on 10. structures internal to the chest wall including vessels, pleura and other structures.
Apart from these adverse effects there are always possible complical procedure such as, but not limited to, infection, nerve damage, and pain which may not be related to the implant.
