Unmatched real-world data

The GLOBAL SYMPLICITY REGISTRY has demonstrated the safety and efficacy of the Symplicity™ blood pressure procedure in a variety of patients representative of daily clinical practice, making it a vital source of insights for patient selection. Signifcant blood pressure reductions were sustained out to three years in both office and 24-hr BP measures.1-3

Global RDN insights

Prof. Markus Schlaich discusses GLOBAL SYMPLICITY REGISTRY data for patients with resistant hypertension.

Safety results

The GLOBAL SYMPLICITY REGISTRY demonstrated procedural and long-term safety of the Symplicity blood pressure procedure through three years in patients from real clinical practice.1-3

Advancing the study of long-term results

GSR DEFINE is a prospective, multi-center, single-arm, non-interventional and open-label registry that will document the long-term safety and efficacy of the Symplicity blood pressure procedure.

  • 5,000 patients to be enrolled
  • 300+ sites worldwide
  • One to fve years of follow-up
