• Target: 5,000
• Locations: 2 countries
• Sites: 2

Brief Summary

This is a prospective, multi-center, single-arm, non-interventional and open-label registry. The purpose of the registry is to document the long-term safety and effectiveness of renal denervation in a real world patient population with hypertension GSR DEFINE is the continuation of the Global SYMPLICITY Registry and collectively will enroll approximately 5000 patients with hypertension who undergo the renal denervation procedure, from over 300 sites worldwide. Subjects included in GSR DEFINE will be followed for a minimum of 1 year and up to 5 years post-procedure. Patients with uncontrolled hypertension will be enrolled in accordance with the inclusion criteria specified in the protocol.

Conditions

Hypertension

Outcome Measures

Primary Outcomes (1)

• BP Measurements

  Blood pressure changes from baseline (Office Setting and 24-hr Ambulatory measurements)

  6 months

Study Arms (1)

Renal Denervation Treatment

All patients treated with renal denervation procedure will be enrolled as part of this single arm registry

Device: Medtronic Renal Denervation System

Interventions

Medtronic Renal Denervation System DEVICE

The Symplicity renal denervation system is comprised of a single-use, disposable catheter and a reusable radiofrequency (RF) generator. The Symplicity renal denervation system has CE Marking for the intended use of delivering low-level radiofrequency energy through the wall of the renal artery to denervate the human kidney.

Renal Denervation Treatment

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Subjects undergoing renal denervation procedure for hypertension

You may qualify if:

• Age ≥ 18 years or minimum age as required by local regulations
• The patient is an acceptable candidate for renal denervation based upon the Instructions For Use for the Medtronic renal denervation system. The procedure must be performed with an initial use, market-released Medtronic renal denervation catheter.
• The patient or legal representative has been informed of the nature of the registry has consented to participate and authorized the collection and release of this medical information by signing a consent form ("Patient Informed Consent Form" or "Patient Data Release Authorization Form")
