Intended Use

The NSO Supplemental Instrument Trays are intended to organize, protect, and transport instruments during steam sterilization and subsequent storage. NSO Supplemental Instrument Trays are not intended to maintain sterility; they are intended to be used in conjunction with a validated FDA cleared sterilization wrap in order to maintain sterility of the enclosed medical instruments.

Device Story

NSO Supplemental Instrument Trays consist of anodized aluminum lids and base trays with silicone instrument holders and stainless steel hardware. Designed to organize, protect, and transport reusable orthopedic instruments (e.g., reamers, depth gauges, awls) during steam sterilization and storage. Trays are perforated to allow steam penetration. Used in clinical settings; operated by healthcare staff. Trays are not sterile barriers; must be used with validated sterilization wrap. Sterilization performed via pre-vacuum steam cycle (132°C, 4 min exposure, 40 min dry time). Trays facilitate organized instrument handling, ensuring instruments remain secure and accessible for surgical procedures. Benefits include efficient instrument management and effective sterilization of complex orthopedic tools.

Clinical Evidence

Bench testing only. Validation included sterilization efficacy (SAL 10⁻⁶) per ISO 17665-1 and AAMI TIR12, dry time validation (40 minutes), and cleaning validation (hemoglobin, protein, TOC). Biocompatibility and reprocessing limits were established via reference to original predicate testing.

Technological Characteristics

Materials: Anodized aluminum, medical-grade Class VI silicone, stainless steel. Design: Perforated lid/base tray with silicone instrument holders. Sterilization: Pre-vacuum steam (132°C). Connectivity: None. Software: None.

Indications for Use

Indicated for organizing, protecting, and transporting reusable orthopedic instruments during steam sterilization and storage. Used in conjunction with validated FDA-cleared sterilization wrap. No specific patient population or contraindications defined.

Regulatory Classification

Identification

A sterilization wrap (pack, sterilization wrapper, bag, or accessories, is a device intended to be used to enclose another medical device that is to be sterilized by a health care provider. It is intended to allow sterilization of the enclosed medical device and also to maintain sterility of the enclosed device until used.

*For use with the Reamer Tray

- 10. Performance Data: Since the Flexible Reamer Tray contains with a worst case dimension (smaller lumen diameter and longer length) compared to the NSO Supplemental Instrument Trays, non-clinical performance testing was conducted to establish substantial equivalence of the Flexible Reamer Tray to the predicate device. Sterilization testing was conducted to confirm that a sterility assurance level (SAL) of 106 was achieved at the validation sterilization parameter in the pre-vacuum steam sterilization cycle according to ISO 17665-1 and AAMI TIR12. A dry time validation was performed and was successful in determining an effective dry time of 40 minutes for the validated pre-vacuum steam sterilization cycle. The cleaning and sterilization study demonstrated that the previously validated cleaning and sterilization parameters for the predicate NSO Supplemental Instrument Trays were effective and will adequately clean and sterilize the Flexible Reamer Tray. No changes are being made to the design or materials of the NSO Supplement Trays; therefore, testing with regard to biocompatibility and limits of reprocessing was not repeated and the original testing results are still applicable. Results of the testing demonstrated that the device is safe and effective for its intended use.
- 11. Conclusion: Based on the intended use, technological characteristics, performance data, and nonclinical tests performed, the subject NSO Supplement Trays are as safe and as effective as, the legally marketed predicate device, Ellipse Supplemental Instrument Trays cleared under K151594 under regulation 21 CFR 880.6850, product code KCT.
