The Artrocool® - S is a typical cold liquid recirculating cryotherapy device. The Artrocool® -S is an insulated ice chest-like box with a closed loop liquid recirculating pump and tubing. The tubing connects to a variety of cuffs designed to be placed on or around injured or post surgical body structures, limbs or joints. The device operates by the use of a water filled cartridge and an insulated chest. The water filled bottle is frozen solid prior to first use. When the bottle is frozen, it is placed within the insulated chamber of the Artrocool. A 4:1 mixture of water and alcohol is poured into the fluid reservoir (balancing container) until full. The pump is circulated with the connecting tubing and cuff attached. Once both are filled and all air bubbles have been purged from the system the unit is ready for service.

Here's an analysis of the provided text regarding the Artrocool®-S Water Circulating Cold Pack, focusing on acceptance criteria and the study that proves its effectiveness, as per your requested format:

Important Note: The provided document is a 510(k) Premarket Notification for a medical device (Artrocool®-S Water Circulating Cold Pack). It establishes "substantial equivalence" to legally marketed predicate devices, rather than directly demonstrating novel performance through a clinical trial with specific acceptance criteria. Therefore, some of your requested points, such as "effect size of how much human readers improve with AI vs without AI assistance" or "sample size for the training set," are not applicable to this type of submission, as it doesn't involve AI or a traditional clinical study to prove efficacy in the same way a new drug or diagnostic might.

The "study" in this context is the comparison of the device's features and performance parameters to those of existing, legally marketed predicate devices to establish substantial equivalence.

1. Table of Acceptance Criteria and the Reported Device Performance

Since this is a 510(k) submission based on substantial equivalence, there aren't explicit "acceptance criteria" in the traditional sense of a clinical trial's primary endpoint. Instead, the acceptance criteria are implicitly defined by the characteristics and performance of the predicate devices that the Artrocool®-S is compared against. The "reported device performance" is essentially how the Artrocool®-S aligns with or performs similarly to these predicate devices.
