Intended Use

The Surgical and Prosthetic Trays are intended for organizing, sterilizing and storing of instruments. The Surgical and Prosthetic Trays are not intended to maintain sterility and are to be used in conjunction with a legally marketed, validated sterilization pouch.

Device Description

The proposed Surgical and Prosthetic Trays are reusable perforated containers that are intended to store and organize the instruments needed before, during and after implant surgery and the prosthetic procedure as well as hold instruments during sterilization.

The Trays are containers composed of three main components: a lid, a base and an overlay, which are all made of polyphenylsulfone (Radel R5000NT). The trays have co-molded silicone tooling supports and silicone rubber grommets to hold instruments. The base and overlay are custom printed to indicate the guided surgery or prosthetic procedure workflow and the position of the instruments within the tray for the different product lines.

The proposed Surgical and Prosthetic Trays are available in two tray sizes. The Surgical trays are available in medium size with outer dimensions of 7.3 x 5.5 x 2.4 inches and the Prosthetic trays are available in small size with outer dimensions of 5.4 x 3.9 x 2.4. Each tray size is offered in 2 inner tray configurations with varied instrument loads, see Table 1.

AI/ML Overview

The provided text describes the acceptance criteria and the studies that prove the device meets these criteria for "Surgical and Prosthetic Trays" (K220791).

Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

Test NameTest MethodologyAcceptance CriteriaReported Device Performance
Sterilization cycle validationANSI/AAMI/ISO 17665-1:2006/(R)2013, ISO 17665-2:2009Sterility assurance level (SAL) of ≤ 10-6Pass

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

The document does not specify sample sizes for individual tests (e.g., number of trays tested for sterilization, drying, or cleaning). It refers to the "Proposed device" for sterility and drying validation, and the "Predicate device" for cleaning, reprocessing, simulated use, packaging, and cytotoxicity.

The data provenance is from non-clinical performance data, meaning these are laboratory or bench tests, not involving human subjects. The country of origin of the data is not explicitly stated, but the submission is to the U.S. FDA, and the company is Dentsply Sirona Inc., with an address in York, Pennsylvania, USA. The testing methodologies are based on international standards (ANSI/AAMI/ISO, ISO, AAMI TIR) which are widely recognized.

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

This information is not provided in the document. For these types of non-clinical, performance-based tests (sterilization, drying, material properties), the "ground truth" is typically established by adhering to referenced international standards and specifications, rather than expert consensus on individual cases. The "experts" would be the personnel performing and analyzing these standardized tests, whose qualifications are usually governed by quality management systems within the testing facilities.

4. Adjudication Method for the Test Set

This information is not provided. Given the nature of the tests, which are objective measurements against predefined criteria (e.g., SAL ≤ 10-6, ≤ 3% weight gain, specific chemical limits), an adjudication method in the sense of multiple expert reviews is not typically applicable. The results are usually a direct outcome of the test protocol.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating the performance of diagnostic imaging devices or algorithms where human readers interpret medical images. The device in question is a surgical tray for sterilization and storage, which does not involve human interpretation of data in the same way.

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

No, this is not applicable. The device is a physical sterile processing tray, not a software algorithm. Therefore, "standalone algorithm performance" is not a concept that applies to this device.

7. The Type of Ground Truth Used

The "ground truth" for these tests is based on objective criteria and methodologies defined by recognized international and national standards (e.g., ANSI/AAMI/ISO, ISO, AAMI TIR, ISTA). For example:

  • Sterilization: Sterility Assurance Level (SAL) ≤ 10-6.
  • Drying: No visible moisture, ≤ 3% weight gain.
  • Cleaning: Absence of visible soil and specific limits for protein and TOC content.
  • Material Biocompatibility (Cytotoxicity): Defined inhibition of cell proliferation percentage.
  • Mechanical Performance (Reprocessing, Simulated Use): Absence of visible damage, deformation, significant wear.

8. The Sample Size for the Training Set

Not applicable. The device is a physical product (surgical tray), not an AI/ML algorithm. Therefore, there is no "training set" in the context of machine learning.

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

Not applicable for the same reason as point 8.

Dear Courtney Clark:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

Non-Clinical Performance Data

The proposed Surgical and Prosthetic Trays are reusable devices provided non-sterile which need to be end user sterilized. Sterilization of the proposed trays was validated according to the FDA guidance document, "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling".

Non-clinical testing data submitted, referenced, or relied upon, including acceptance criteria and set specifications in test methodology and standards, are summarized below:

§ 880.6850 Sterilization wrap.

(a)
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.(b)
Classification. Class II (performance standards).
