Brief Summary:
The REDUCE HTN: REINFORCE study is being conducted to determine whether the Vessix Reduce™ Catheter and Vessix™ Generator for the treatment of uncontrolled hypertension (off-treatment office systolic blood pressure ≥150 mmHg and ≤180 mmHg) shows acceptable performance at 8 weeks when compared to a masked procedure (renal angiogram).
