Study Summary

The purpose of this study is to demonstrate that the rate of clinically relevant complications associated with CyPass Micro-Stent placement and stability using the CyPass 241-S applier, as determined at 36 months in the postmarket setting, is less than the pre-specified performance target, which is based on experience with the CyPass Model E applier in COMPASS trial TMI-09-01 (NCT01085357).
