About the Procedure

The SPYRAL HTN clinical trial is evaluating an investigational device for high blood pressure.

The purpose is to provide researchers information about the safety and effectiveness of an investigational procedure to help reduce blood pressure in patients whose blood pressure is not controlled despite medication and lifestyle adjustments.

The procedure delivers energy to the nerves in the kidneys that help regulate blood pressure. Regulating the nerves may help the kidneys better manage blood pressure.

SPYRAL = the name of the investigational device used in the trial

HTN = the short form for "hypertension," which also means "high blood pressure"
