The continued clinical experience addendum is a prospective, multi-center, non-randomized, interventional study to evaluate the safety and effectiveness of the Harmony TPV system. All implanted subjects will receive the Harmony TPV 22 or Harmony mTPV 25 device. This phase allows up to 45 subjects implanted with TPV 22 in the United States and Canada, and up to 84 subjects implanted with mTPV 25 in the United States.
The Post Approval Phase (PAS) addendum is a prospective, multi-center, non-randomized, post-market study to evaluate the safety and effectiveness of the Harmony TPV system in the United States. All implanted subjects have been implanted with the Harmony TPV 22 or Harmony mTPV 25 device during the pivotal or CAS phase of the study. The PAS addendum extends follow-up from five years to ten years for consenting subjects.
