IVD (In Vitro Diagnostic)

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

Here's why:

Intended Use: The intended use clearly states that the system is for the liquid chemical sterilization of cleaned, immersible, and reusable critical and semi-critical heat-sensitive medical devices. This is a process performed on medical devices themselves, not on biological samples from a patient for diagnostic purposes.
Device Description: The device description details a system that uses a chemical sterilant (peracetic acid) and filtered water to sterilize medical instruments. This aligns with a sterilization process, not an in vitro diagnostic test.
Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring analytes
- Providing information for diagnosis, monitoring, or prognosis of a disease or condition
- Using reagents or assays for in vitro testing

The device is a medical device used for reprocessing other medical devices to make them safe for reuse.

Description of Device 3.

The SYSTEM 1 endo Liquid Chemical Sterilant Processing System is a liquid chemical sterilization system. utilizing peracetic acid to process totally immersible semi-critical medical devices and their accessories. The system consists of the SYSTEM 1 endo Processor and S40 Sterilant Concentrate, interchangeable Processing Trays/Containers, and Quick Connects. The current submission is provided to describe modifications for:

Obsolescence and replacement of compressor ●
Obsolescence and replacement of upper lid seal ●

The SYSTEM 1 endo Processor is an automated, self-contained device that uses S40 Sterilant Concentrate to create and maintain the conditions necessary for liquid chemical sterilization in 6 minutes. Following processing, the liquid chemically sterilized articles are rinsed with 0.2 micron filtered potable water and are ready for use or may be prepared for storage. The processor, which is computer controlled and continually monitored, provides printed documentation of each cycle.

The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate. Upon loading the single-use cup, the active ingredient in S40 - peracetic acid - is combined with inert ingredients (builders) to form a use dilution which inhibits corrosion of metals, polymers and other materials.

The interchangeable processing trays/containers are made to accommodate a variety of semi-critical instrument types and models. Each container is designed to maintain instruments in position while specific SYSTEM 1 endo Quick Connects, if required, facilitate delivery of the sterilant use-solution and rinse water to internal channels. Table 1 compares the proposed and predicate devices.

After LCS processing, the liquid chemically sterilized articles are rinsed with 0.2 micron filtered potable water and are ready for use or may be prepared for storage.

The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate. Upon loading the single-use cup, the active ingredient in S40 - peracetic acid - is combined with inert ingredients (builders) to form a use dilution which inhibits corrosion of metals, polymers and other materials.

The interchangeable processing trays/containers are made to accommodate a variety of semi-critical instrument types and models. Each container is designed to maintain instruments in position while specific SYSTEM 1 endo Quick Connects, if required, facilitate delivery of the sterilant use-solution and rinse water to internal channels. Tables 1 and 2 compare the proposed and predicate devices.
