## J. Comparison to the Predicate
The table above illustrates the similarities and differences between the subject and predicate devices. The basic technological and operating principles are the same for both devices. Although the indications for use wording is not identical, both the subject and predicate devices are for airway management. Both the subject and predicate devices are disposable, sterile, single patient use devices. The subject devices are substantially equivalent to the predicate device. There are no significant differences that would affect safety and efficacy.
#### K. Performance Data
The bench testing performed verifies that the performance of the subject device is substantially equivalent in terms of critical performance characteristics to the predicate device. These tests include:
- Testing performed included visual inspection, Dimensional testing, Bonding strength (main tube to the side arm, inflation tube and connector), Tube curvature, cuff restrained burst, Bevel angle Cuff inflation, Kink resistance, Cuff herniation, Cuff diameter, Tube collapse and Tracheal seal testing, as well as testing required by ISO 10993-1 Fifth Edition 2018-08 - Biological Evaluation of Medical Devices -- Part 1: Evaluation and testing within a risk management process.
The testing performed verifies that the performance of the subject device is substantially equivalent in terms of critical performance characteristics to the predicate device.
