Intended Use

The THINK Surgical TCAT® TKA Instrument Tray Set is intended to protect, organize, and deliver to the surgical field TCAT® tools, instruments and accessories. The trays allow sterilization of tools, instruments and accessories, and maintain sterility of the enclosed devices until used. The trays are wrapped with an FDA-cleared sterilization wrap during the pre-vacuum autoclave sterilization process.

Device Description

The TCAT® TKA Instrument Tray Set is intended only for use with TSolution One® Total Knee Application instruments, tools and accessories. These trays are used to enclose and hold the instruments tools and accessories in an organized manner during the sterilization process and subsequent storage and transportation to and from the surgical suite. The trays are designed to fit any standard autoclave and are constructed primarily of anodized aluminum meeting biocompatibility requirements and are compatible with repeated steam sterilizations. The trays have perforations to facilitate sterilant penetration, evacuation and drying. Since the trays are perforated, an FDA-cleared sterilization wrap must be used to maintain sterility of the contents.

The trays have the same size and same basic configuration of the predicate device: a rectangular base with a latchable lid. The trays have perforations with an evenly distributed hole pattern on the lid, bottom, and sides to allow sterilant penetration. The bottom surface and interior shelves of the trays contain stanchions designed to separately hold each individual instrument, tool and accessory for effective sterilant exposure, evacuation and drying during the entire duration of the sterilization process, as well as ease of locating each instrument when placing in or removal from the tray.

The sterilization trays have been tested only with THINK Surgical instruments, tools and accessories for a 4 minute sterilization cycle of pre-vacuum steam sterilization at 132°C, with a 45 minute dry time. While reuseable, these trays will not be serviced or repaired.

AI/ML Overview

The provided document, K200632, details the 510(k) premarket notification for the THINK Surgical TCAT® TKA Instrument Tray Set. It focuses on demonstrating substantial equivalence to a predicate device (TCAT® THA Instrument Tray Set) through non-clinical performance testing.

Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:

Device: TCAT® TKA Instrument Tray Set
Purpose of Device: Intended to protect, organize, and deliver TCAT® tools, instruments, and accessories to the surgical field, allow for their sterilization, and maintain sterility.


1. Table of Acceptance Criteria and Reported Device Performance

Non-Clinical Performance TestingPurpose (What was being tested)Acceptance CriteriaReported Device Performance/Results
Sterilization EfficacyTo verify the TCAT® TKA Instrument Tray Sets containing the maximum load were inoculated with biological indicators placed in areas of the trays deemed most difficult for sterilant (steam) to penetrate. Following inoculation, the trays were wrapped in FDA-cleared sterilization wraps.- All biological indicators (BIs) must be incubated for a minimum of 7 days at 55°C-60°C- The positive control for the SAL testing must show characteristic growth of the indicator organism- Valid temperature data must be collected for each product probe location- Temperature probes used during profiling of the test article must be within ±0.5°C of at least one post calibration reference temperature that is representative of the profiling cycles- All directly-inoculated test article components must demonstrate to contain no bacteriostatic properties by showing growth of G. stearothermophilus during method suitability testingThe study indicated that the BI Overkill method provided a six-log reduction of the indicator organism.
PackagingTo verify the TCAT® TKA Instrument Tray Sets were evaluated with maximum load, wrapped according to use instructions and in the shipping configuration according to a shipping validation test.- Is the packaging or parts of the Application Tray damaged?- Is the Packaging or parts of the Base Tray damaged?- Are the labels and packing list still affixed and legible?PASS
ReprocessingTo verify the TCAT® TKA Instrument Tray Sets were evaluated for cleanability according to the user instructions.- Observer shall provide each participant with an IFU- Observer shall ask each participant to read the IFU carefully- Observer shall ask each user to simulate the reprocessing steps according to the IFU- Observer shall fill out the data collection sheetThe table states "indicates all reprocessing steps PASS" as part of the criteria, implying that the passing of these observational checks constitutes the acceptance.PASS
BiocompatibilityTo verify the TCAT® TKA Instrument Tray Sets were evaluated for biocompatibility according to ISO 10993-1.MEM Elution Study: Test article meets a passing score of 2 or below; test article is not considered to have a cytotoxic potential.PASS
Use and Sterile Processing GuideTo verify the TCAT® TKA Instrument Tray Sets were evaluated in accordance with the appropriate guidances. (This likely refers to ease of use and ability to properly load/unload for sterile processing).- Participant is able to load components in the tray- Participant is able to load components in the tray with the aid of visual indications showing storage location of each instrument- Participant is able to carry one Instrument Tray- Participant is able to load all components in the tray without requiring an additional toolParticipant is able to remove all components in the tray without requiring an additional toolPASS

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the specific sample sizes (number of trays or iterations) used for each test. For tests like "Sterilization Efficacy," it refers to "TCAT® TKA Instrument Tray Sets containing the maximum load," implying multiple units were tested to ensure robustness. Similarly, for "Packaging" and "Reprocessing," the evaluation would involve a certain number of units.

Data Provenance: The document does not specify the country of origin for the data. The studies are non-clinical (laboratory-based) and conducted to regulatory standards (e.g., ANSI/AAMI/ISO, ASTM, ISO 10993), which typically do not involve human subjects or retrospective/prospective data collection from clinical practice. They are "prospective" in the sense that the tests were designed and executed to evaluate the device.


3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document does not mention the use of external experts or their qualifications for establishing ground truth for any of the non-clinical tests. For the reprocessing and use guidance tests, an "Observer" is mentioned, who would likely be trained personnel conducting the evaluation according to a defined protocol. These are laboratory-based engineering and performance validation tests, not clinical studies requiring physician or radiologist expertise for ground truth.


4. Adjudication Method for the Test Set

Adjudication methods (like 2+1, 3+1) are typically used in clinical studies for interpretation of imaging or clinical outcomes by multiple experts. Since this submission relates to a non-clinical device performance evaluation (sterilization, packaging, cleaning, biocompatibility, ease of use of a surgical tray), such adjudication methods are not applicable and are not mentioned in the document. The tests have predefined, measurable acceptance criteria.


5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, an MRMC comparative effectiveness study was not done. MRMC studies are relevant for AI/imaging devices where human interpretation of medical images is involved, to assess the impact of AI assistance on human reader performance. This device is a surgical instrument tray (sterilization wrap, not an imaging or diagnostic AI), and as such, MRMC studies are not applicable. The document explicitly states: "No clinical or animal testing were required."


6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

This question is not applicable to the device described. This is a physical medical device (an instrument tray for sterilization), not an algorithm or AI system. Therefore, the concept of "standalone performance" for an algorithm doesn't apply. The tests described are for the physical properties and performance of the tray itself.


7. The Type of Ground Truth Used

The "ground truth" for these non-clinical tests is established by:

  • Physical/Biological Standards: For sterilization efficacy, the ground truth is the complete eradication of specified biological indicators (e.g., 6-log reduction of G. stearothermophilus spores), verified through incubation protocols.
  • Engineered Specifications and Standards: For packaging, cleaning, biocompatibility, and use, the ground truth is defined by meeting pre-specified engineering tolerances, regulatory standards (e.g., ISO, ASTM), and user requirements (e.g., no damage, legible labels, cytotoxic potential score, ability to load instruments without additional tools). These are objective, measurable criteria.

8. The Sample Size for the Training Set

Not applicable. This product is a physical device (surgical instrument tray), not an AI/machine learning model that requires a training set.


9. How the Ground Truth for the Training Set was Established

Not applicable for the reason stated above.

Technological Characteristics Comparison Table

Three fundamental characteristics are the same between the two devices:

    1. Basic design: Both the TCAT®TKA Instrument Tray Set and the predicate device have a basic lid/base design with latches, handles, perforations, and contoured inserts or sections for containing items for sterilization, storage and transport. General size, shape, weight and materials are the same.
    1. Role in sterile barrier system: The TCAT® TKA Instrument Tray Set and the predicate device must be wrapped with an FDA-cleared sterilization wrap to maintain sterility. Neither the subject device or the predicate contains gaskets, valves nor filters.
    1. Fundamental technology: The TCAT®TKA Instrument Tray Set and the predicate device allow the sterilant (steam) to penetrate and render its contents sterile by relying on surface perforations.
