Details and patient eligibility

About

The primary objective of the study is to generate feasibility safety and performance data for the 4Tech TriCinch Coil System in symptomatic patients suffering from moderate to severe functional tricuspid regurgitation with annular dilatation.

The TriCinch Coil System is a percutaneous catheter-based medical device for tricuspid valve repair.
