Intended Use
The STERN FIX Sternal Stabilization System is intended for closure and stabilization of the sternum following sternotomy, through the intercostal spaces, in order to promote its fusion.
Device Description
The STERN FIX is a long-term implantable postoperative sternal stabilization system that closes and stabilizes the sternum after a sternotomy. The STERN FIX is a clamping device consisting of two parts, male and female, which match telescopically with one another to form the sternal stabilization system. Both male and female parts have a curved arm that catches one of the two halves of the sternum laterally and approximates them until the sternum is securely fixed. Five sizes of the STERN FIX are available for use with different sternum thicknesses. The STERN FIX can be cut and removed for emergent, and long-term, re-entry through the sternum. The predicate device was originally made of PEEK-OPTIMA™. This 510(k) introduces a new variant of the product made of carbon-fiber reinforced (CFR) PEEK-OPTIMA™. This new variant also presents some minor geometry changes with respect to the predicate device, to adapt the product to the new material.

No
The device description and performance studies focus on the mechanical properties and function of a physical implant for sternal stabilization. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.

No.
The device is a sternal stabilization system intended for mechanical closure and stabilization of the sternum to promote fusion, rather than to treat or cure a disease or condition itself.

No

The device is an implantable mechanical system used for stabilizing the sternum after surgery, not for diagnosing a condition.

No

The device description clearly states it is a "long-term implantable postoperative sternal stabilization system" consisting of physical components (male and female parts, curved arms) made of PEEK-OPTIMA™ or carbon-fiber reinforced PEEK-OPTIMA™. This is a hardware device, not software.

Based on the provided information, the STERN FIX Sternal Stabilization System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is for "closure and stabilization of the sternum following sternotomy, through the intercostal spaces, in order to promote its fusion." This describes a surgical implant used to physically support and stabilize bone, not a device used to examine specimens derived from the human body for diagnostic purposes.
  • Device Description: The description details a "long-term implantable postoperative sternal stabilization system" consisting of physical components (male and female parts, curved arms) made of specific materials. This aligns with a surgical implant, not an IVD.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in biological samples
    • Providing information for diagnosis, monitoring, or screening of diseases or conditions

Therefore, the STERN FIX Sternal Stabilization System is a surgical implant, not an IVD.

Device Description

The STERN FIX is a long-term implantable postoperative sternal stabilization system that closes and stabilizes the sternum after a sternotomy. The STERN FIX is a clamping device consisting of two parts, male and female, which match telescopically with one another to form the sternal stabilization system. Both male and female parts have a curved arm that catches one of the two

halves of the sternum laterally and approximates them until the sternum is securely fixed. Five sizes of the STERN FIX are available for use with different sternum thicknesses. The STERN FIX can be cut and removed for emergent, and long-term, re-entry through the sternum. The predicate device was originally made of PEEK-OPTIMA™. This 510(k) introduces a new variant of the product made of carbon-fiber reinforced (CFR) PEEK-OPTIMA™. This new variant also presents some minor geometry changes with respect to the predicate device, to adapt the product to the new material.

Indications for Use

The STERN FIX Sternal Stabilization System is intended for closure and stabilization of the sternum following sternotomy, through the intercostal spaces, in order to promote its fusion.

| Device Design | The STERN FIX device consists of two parts, male and female, which match telescopically with one another to form the fixation system. Both male and female parts have a curved arm that catches laterally one of the two halves of the sternum and approximates them until the sternum is securely fixed. Both parts present a set of teeth that, together, form a ratchet mechanism that allows their movement in the closing direction and, at the same time, impedes their backward movement. The tightening of both implant parts (male and female) is carried out using an application tool.

| Accessories | Four instruments are used to implant the device:
• A depth gauge (SCI0000) to select the appropriate STERN FIX size.
• Forceps (SCI0501) to tighten and adjust the STERN FIX during its implantation.
• A cutter (SCI0200) to cut the excess segment of the male part or cut the device safely in case of need of device removal.
• A retractor (SCI0300) to ease the introduction of the STERN FIX in the intercostal spaces. | Besides the four instruments already included in the cleared version of the product (SCI0000, SCI0501, SCI0200, SCI0300), a new alternate cutter (SCI0700) is added. This instrument may be used as an alternative to SCI0200, if preferred by the user, to cut the excess segment of the male part. |

Technological characteristics, comparison to predicate device

Technological Characteristics and Substantial Equivalence

The changes proposed for the modified STERN FIX do not change the indications for use of the original product, nor its contraindications, potential side effects or adverse events. The group of users and the use environment also remain unchanged. The material change does not imply any

6

new or increased biocompatibility concerns, based on the risk assessment performed. The changes on the geometry do not modify the critical dimensions of the product, nor do they imply a modification of the design requirements or the final product specifications. Similarly, the sternum thickness and width range for which the device can be used, as well as the implantation method, remain the same. Finally, the addition of a new accessory (SCI0700) does not affect the directions of use nor the implantation method of the device.

In summary, the modified STERN FIX is substantially equivalent to its predicate device with regards to indications for use, technological characteristics, principles of operation and performance.

Performance testing

Performance testing was conducted to characterize the capacity of the modified STERN FIX, as a sternal stabilization system, to withstand the forces that act upon the sternum and the whole fixation system once the products have been implanted. The results of the tests confirm the adequate performance of the device, and that it is able to achieve its intended use.

Performance testing has demonstrated that the technological characteristics of the modified STERN FIX do not raise any new safety or effectiveness issues and that it will perform as intended in the clinical setting. A summary of the tests performed follows:

No clinical testing was performed to support this submission.

Conclusion

Based on the comparison of the intended use (based on the indications for use), product technical characteristics, principles of operation and performance, the modified STERN FIX has demonstrated substantial equivalence to the previously cleared STERN FIX product. The differences do not raise new issues of safety or effectiveness, based on the risk assessment
