Therefore, no biocompatibility testing was required for the subject Millipede 070 Aspiration Catheter and Perfuze Aspiration Tube Set.

### Sterilization

The Millipede 070 Aspiration Catheter and Perfuze Aspiration Tube Set are sterilized using a validated EO process with a sterility assurance level of 1x10 °. There is no change to the sterilization method used for the subject Millipede 070 Aspiration Catheter compared to the predicate device. Therefore, no additional sterilization data was required for the subject Millipede 070 Aspiration Catheter.

A different sterilization cycle will be used for the subject Perfuze Aspiration Tube Set compared to the predicate device. A validation was conducted for this cycle using the overkill method according to ISO 11135, "Sterilization of Health-Care Products - Ethylene Oxide - Requirements for the Development, Validation and Routine Control of a Sterilization Process for Medical Devices".

# Shelf Life and Packaging

The subject and predicate devices have an identical shelf life and packaging configuration. To ensure that the new sterilization cycle for the Perfuze Aspiration Tube Set does not impact integrity of the sterile barrier, packaging testing was conducted following sterilization with the new process. The device packaging met established specifications.

# Animal Study

No animal study was deemed necessary to demonstrate substantial equivalence between the subject and predicate devices.

## Clinical Data

No clinical study was deemed necessary to demonstrate substantial equivalence between the subject and predicate devices.

## Conclusion

The subject and predicate devices have the same indications for use, operating principle, and design. The different sterilization cycle used for the Perfuze Aspiration Tube Set does not raise different questions of safety or effectiveness. The successful completion of sterilization and packaging validation demonstrates that the subject device is substantially equivalent to the predicate device.
