## Indications for Use

The MTS System (Multiple Tray Sterilization System) is indicated for enclosing other medical devices that are to be sterilized by a healthcare provider. It is intended to allow sterilization of the enclosed materials and maintain sterility for up to 30 days. The unit must be used with the MTS System Transfer Cart, MTS System Filters and MTS System Integrity Locks. The MTS System is intended to be used in prevacuum steam sterilizers with a prevacuum cycle of 270°F and exposure time of 4 minutes. Use no more than 3 trays per shelf or 25 lbs. per tray. The MTS System was tested and validated with rigid instruments containing lumens with an inner diameter of .7mm and an overall length of 500mm as well as lumens with an inner diameter of 1.0mm and an overall length of 850mm. Do not use with instruments containing lumens with an inner diameter smaller than .7mm and an overall length longer than 500mm or lumens with an inner diameter smaller than 1.0mm and an overall length longer than 850mm. Use only uncovered, perforated or wire mesh general delivery trays within the MTS System.

## Device Story

MTS225 and MTS300 are stainless steel sterilization cabinets designed to enclose medical devices during steam sterilization; used with MTS System Transfer Cart, disposable filters, and integrity locks. Healthcare providers load uncovered, perforated, or wire mesh trays into the cabinet; cabinet is deployed into a prevacuum steam sterilizer via the transfer cart. System facilitates sterilization and maintains sterility for 30 days post-processing. Optional STEAMPlus tray record cards/integrators may be used. Device benefits include standardized containment for reusable instruments, ensuring sterility maintenance during storage and transport. The MTS225 is a smaller, lighter version of the predicate MTS300, offering identical sterilization performance with reduced drying time requirements.

## Clinical Evidence

Bench testing only. Studies performed per ANSI/AAMI ST77:2013. Validated sterilization efficacy to 10^-6 SAL for rigid instruments with lumens (0.7mm ID/500mm length and 1.0mm ID/850mm length). Confirmed 10-minute minimum dry time and 30-day sterility maintenance following rigorous outdoor transportation and storage.

## Technological Characteristics

16-gauge stainless steel cabinet; disposable heavy-duty sterilization wrap filters; adjustable transfer cart for deployment. Prevacuum steam sterilization (270°F, 4-minute exposure). Dimensions vary by model (MTS225/MTS300). No electronic components or software.

## Regulatory 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.

Dear Annette Hillring:

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.

{1}------------------------------------------------

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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

The MTS System is intended to be used in prevacuum steam sterilizers with a prevacuum cycle of 270°F and exposure time of 4 minutes. Use no more than 3 trays per shelf or 25 lbs. per tray.

The MTS System was tested and validated with rigid instruments containing lumens with an inner diameter of 0.7mm and an overall length of 500mm as well as lumens with an inner diameter of 1.0mm and an overall length of 850mm. Do not use with instruments containing lumens with an inner diameter smaller than 0.7mm and an overall length longer than 500mm or lumens with an inner diameter smaller than 1.0mm and an overall length longer than 850mm.

Use only uncovered, perforated or wire mesh general delivery trays within the MTS System.

| Comparison of<br>Technological<br>Characteristics<br>with the<br>Predicate<br>Device | Modifications introduced into the MTS300 Multiple Tray Sterilization<br>Systems do not affect the technological characteristics.
