SaMD (Software as a Medical Device)

No

The device description explicitly states that the purpose of the 510(k) is to add MR safety information to the labeling of existing Smith & Nephew Knee Systems. These knee systems are clearly described as physical implants (unicompartmental, total knee, patello-femoral) intended for surgical implantation with bone cement, which are hardware devices. The submission focuses on labeling changes related to MRI compatibility, not on a software component.

IVD (In Vitro Diagnostic)

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

Here's why:

Intended Use/Indications for Use: The intended use clearly describes the device as a knee implant used for surgical procedures to treat various knee conditions like arthritis, failed previous surgeries, and fractures. This is a therapeutic device implanted in the body.
Device Description: The description confirms the device is a knee system and the purpose of the submission is to add MR safety information to the labeling of these implanted devices.
IVD Definition: An In Vitro Diagnostic device is defined as a medical device intended for use in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes.

Device Description:

The purpose of this Traditional 510(k) is to add MR safety information to the labeling (instructions for use, product labeling and patient implant card) of the subject Smith & Nephew Knee Systems. The technological characteristics, function of the devices, packaging and sterilization remain unchanged. As these products have been in distribution for several years, some parts have undergone changes in the technological characteristics that were assessed in compliance with the FDA's guidanceon "Deciding When to Submit a 510(k) for a Change to an Existing Device" or the FDA predecessor guidance on how to review changes to an existing device. These are not cumulative changes for all Smith & Nephew Knee Systems, but are rather specific changes that only affect certain parts. In the context of this submission, no modifications have been made to the device design, materials, sterilization, or the manufacturing process of the previously cleared devices due to the addition of MR Labeling for this 510(k).

Technological Characteristics

The device design and material of the subject devices are the same as the predicate Smith & Nephew Knee Systems, including substantially equivalent letter to file cleared under the premarket notifications listed in Table 6.1.

Performance Data

Below listed Magnetic Resonance Imaging (MRI) compatibility testing was conducted asper the FDA's guidance and the standards listed below .

1. Magnetically induced displacement force (ASTM F2052)
1. Magnetically induced torque (ASTM F2213)
1. Radiofrequency (RF) induced heating (ASTM F2182-19e2, IEC 60601-2-33, ISO/TS 10974:2018E)
1. MR image artifact (ASTM F2119)

MR Safety testing/ assessments support the appropriate MR parameters and symbols found in the subject device labeling.

As these products have been in distribution for several years, bacterial endotoxin testing was completed in previous submissions. The addition of the MR safety information to thelabeling does not affect the pyrogenicity, therefore, the subject Smith & Knee Systems are still expected to met the acceptable endotoxin limits as stated in the FDA Guidance, "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile," "Pyrogen and Endotoxins Testing: Questions and Answers," and ANSI/AAMI ST72.

Conclusion

In summary, the only differences between the subject devices, including substantially equivalent letter to file catalog items and the commercially available predicate devices were supporting MR safety testing/assessment and the addition of MR safety information to the labeling. These differences are not critical to the intended therapeutic, diagnostic, prosthetic, or surgical use of the subject devices. The subject Smith & Nephew Knee Systems are identical in function, design features, materials, sterilization, manufacturing methods and operational principles to what was previously 510(k) cleared and do not affect the safety and effectiveness of the subject devices when used as labeled. Due to the supporting documentation within this filing, it is conducted that the subject device(s) are substantially equivalent to the predicate device(s).
