When someone cannot control his/her high blood pressure with three or more blood pressure medications they are said to suffer from drug resistant hypertension.

The Rheos® Hypertension Therapy System™ is a high blood pressure treatment which consists of an implantable device designed to electrically activate the body’s own natural blood pressure regulation system in order to treat drug resistant hypertension. To learn how it works see 3 minute video.

More then 300 people in the US and Europe have been implanted with the Rheos Hypertension Therapy System. 

Results published on a group of 13 patients from one early stage trial reported an average systolic blood pressure reduction of 29 mmHg (from 189 to 160) after three months of treatment and 39 mmHg  (from 189 to 150) after 12 months.¹ 

Results published on a separate group of 10 patients from another early stage trial reported an average systolic blood pressure reduction of 24 mmHg after three months of treatment.²

Although the early stage results are encouraging, results from a larger study are needed to determine whether the Rheos high blood pressure treatment Device is safe and works as intended.  For this reason the Rheos hypertension pivotal clinical trial is currently enrolling 300 patients.  The data collected from this study will be used by the FDA to evaluate whether this device should be made available for sale for patients with drug resistant hypertension in the US.
