The device description clearly outlines physical components: a plastic tube housing, a plastic cap, a glass ampoule of growth media, and a paper spore disc. This indicates a hardware-based device, not software-only.
Based on the provided information, yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's a "biological sterilization process indicator" and is used to "monitor adequacy of sterilization." This involves testing a process (sterilization) to determine its effectiveness, which falls under the umbrella of in vitro testing.
- Device Description: The device contains a "growth media" and a "pH indicator," which are used to detect the presence or absence of microbial growth (Bacillus stearothermophilus spores) after the sterilization process. This is a classic example of an in vitro test where a biological sample (the spores) is incubated in a controlled environment to assess a biological outcome.
- Mechanism: The device works by determining if the sterilization process successfully killed the spores. This is done by observing whether the spores grow in the provided media. This is an in vitro assessment of the sterilization process's efficacy.
While the device doesn't directly test a human sample, it is used to evaluate a process that directly impacts patient safety by ensuring medical devices are sterile. The testing is performed outside of the body (in vitro) using a biological indicator.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
ProSpore2 has been tested for Population Stability over an 18-month shelf life. This testing included both D-value stability and Population stability with three separate lots of finished product Prospore2 units. Three lots were tested according to the FDA guidelines for validation of reduced incubation. A 48-hour reduced incubation was validated based on the testing results. The recovery media has been tested to show stability in the recovery of low numbers of injured spores over the 18-month shelf life and the stability of the color change when growth occurred. For all lots tested, the stability of the Resistance Characteristics, Spore Population, Media Recovery and overall effectiveness in monitoring routine steam sterilization cycles has been demonstrated.

DESCRIPTION:
ProSpore2 is a self-contained biological indicator used for determining the efficacy of a 121°C steam sterilization cycle. ProSpore2 is comprised of a plastic tube housing with a plastic cap. Inside the tube is a 1ml glass ampoule of growth media consisting of Tryptic Sov Broth and a pH indicator of Bromocresol Purple. Also inside of the tube housing is a paper spore disc impregnated with a population of 105 Bacillus stearothermophilus spores (ATCC #7953).
OPERATIONAL PRINCIPLES:
The plastic cap of the ProSpore2 vial has short "tines" along its lower edge. When placed on the plastic tube body, the space between the tines allows for the passage of steam into the tube and thus reaches the spore disc. A ProSpore2 unit is placed inside of the sterilizer along with a load to be sterilized. If all parameters are met for the cycle (exposure time and temperature), the steam entering the ProSpore2 capsule will be sufficient to deactivate or kill the spores on the paper disc. Onco the cycle is finished, the ProSpore2 vial is removed from the sterilizer and the cap is pressed down with one's thumb. This seals the vial. After allowing the unit to cool for 10 to 15 minutes, the sides of the plastic tubes are squeezed which will result in crushing the glass of the
1
media ampoule. With this done, the spore disc is now in contact with the recovery media and the ProSpore2 unit can be placed in an incubator and incubated at 55 to 60°C for 48 hours. If the spores were killed in the sterilization cycle, the color of the recovery media will not change. If the cycle was a "failed cycle" and failed to kill the spores, the recovery media will change color from purple to yellow indicating growth.
The change in color is the result of viable spores germinating and consuming the nutrients provided in the growth media. This consumption process involves the release n first on waste products, which increases the acidity of the media, thus lowering the pH and causing the color to change from purple to yellow. Detection of failed steam sterilization cycles is facilitated by the use of ProSpore2. The outer label of the ProSpore2 plastic tube body has a chemical indicator on the label which changes color when exposed to saturated steam at 121°C, making it easy to distinguish processed from unprocessed vials.
STATEMENT OF SIMILARITY TO LEGALLY MARKETED PREDICATE DEVICE
ProSpore2 is similar in composition and function to the "Legally Marketed Predicate Device" ProofPlus.
- both devices are intended for use in monitoring steam sterilization cycles at 121°C
- · both devices utilize a USP recommended strain of B. stearothermophilus bacterial spore as its organism of choice for steam resistance characteristics
- both devices use a paper disc as the spore carrier
- both devices utilize a plastic vial and cap to house the spore disc and media 1 capsule
- both devices contain a sealed recovery media ampoule made of glass 를
- both devices use a pH indicator in the recovery media which turns to yellow when 199 arowth is present
- both devices require that the recovery media ampoule be activated after sterilization by breaking the glass ampoule to release the media to come in contact with the spore disc
- both devices incorporate a "chemical indicator" on the label which will change color when exposed to steam at 121°C so that exposed vials can easily be distinguished from unprocessed vials.
DESCRIPTION OF TESTING:
ProSpore2 has been tested for Population Stability over an 18-month shelf life. This testing included both D-value stability and Population stability with three separate lots of finished product Prospore2 units. Three lots were tested according to the FDA guidelines for validation of reduced incubation. A 48-hour reduced incubation was validated based on the testing results. The recovery media has been tested to show stability in the recovery of low numbers of injured spores over the 18-month shelf life and the stability of the color change when growth occurred. For all lots tested, the
2
stability of the Resistance Characteristics, Spore Population, Media Recovery and overall effectiveness in monitoring routine steam sterilization cycles has been demonstrated.
CONCLUSION.
Raven's ProSpore2 is substantially equivalent in composition and function to the legally marketed predicate device, AMSCO's ProofPlus, for monitoring steam sterilization cycles at 121°C, based on the testing results and analysis of 18-month shelf life stability data.
