#### ട്. Discussion of Technological Comparison and Verification Activities

The Evolution Medium Sterilizers are the same as the predicate devices except for the specific modifications described in this submission. There are no differences in the indications for use or technology (including features, materials, and principles of operation) between the proposed and predicate devices. Therefore, the differences between the proposed and predicate devices are limited to the described modifications, and these proposed changes raise no new concerns of safety and effectiveness when compared to the predicate device.

The following table summarizes the verification activities that were performed with their respective acceptance criteria to ensure that these modifications do not affect the safety or effectiveness of the Evolution Medium Steam Sterilizers.
