A high standard for lowering blood pressure.

The Paradise® Ultrasound Renal Denervation (RDN) system offers a high standard of therapy, harnessing the power of ultrasound energy to treat uncontrolled hypertension.

Hypertension remains a leading cause of cardiovascular issues, including heart failure, stroke, coronary heart disease, and more. And control rates around the globe are declining.

Paradise Ultrasound RDN treats hypertension by ablating the nerves around the renal arteries, disrupting the overactive sympathetic nerves that can cause hypertension.

Designed to deliver.

With exclusive features designed to ensure a safe and effective procedure, the Paradise system offers a proven therapy option to lower your patients’ blood pressure.1-3

SonoWave 360™ transducer


The Paradise system’s SonoWave 360 transducer delivers a complete 360-degree ring of energy4, reaching approximately 80 percent5 of the sympathetic nerves around the renal artery.

7-second energy delivery


Each delivery of ultrasound energy is just 7 seconds, and only 2-3 treatments per main renal artery are needed.* With the Paradise system, treating the distal branches is never required.4

* Treatment site may vary with anatomy. Please refer to Paradise Catheter IFU for treatment strategy.

HydroCooling™ system


Only the Paradise system provides energy delivery with no contact by the transducer, and the HydroCooling system circulates sterile water through the balloon during the procedure for a cooling effect that helps protect the arterial wall.6

Important Safety Information Rx Only.   Brief Summary – Prior to use, please reference the Instructions for Use Indications for Use The Paradise Ultrasound Renal Denervation System (Paradise System) is indicated to reduce blood pressure as an adjunctive treatment in hypertension patients in whom lifestyle modifications and antihypertensive medications do not adequately control blood pressure. Contraindications The Paradise Catheter is contraindicated in any of the following:
  • Renal arteries diameter <3 mm and >8mm
  • Renal artery Fibromuscular disease (FMD)
  • Stented renal artery 
  • Renal artery aneurysm
  • Renal artery diameter stenosis >30%
  • Pregnancy
  • Presence of abnormal kidney (or secreting adrenal) tumors
  • Iliac/femoral artery stenosis precluding insertion of the catheter
  • Failure to use the recommended balloon size may result in renal artery stenosis, dissection, perforation, aneurysm, significant vasospasm requiring intervention, ablation of unintended tissues or structures, and/or no ablation of target tissue achieved.
  • Energy emission in an unintended location may result in unintended tissue damage.
  • Do not move the Paradise Catheter during sonication.
  • Do not sonicate in renal artery at locations with visible plaque. 
  • Do not deliver sonications in an overlapping arterial target zone.
  • Patients with known allergy to contrast medium may be at increased risk of hypersensitivity reactions. 
  • Only use specified coolant (Sterile water) for fluid supply.  DO NOT USE SALINE.
  • Avoid multiple balloon inflations to achieve apposition of the balloon to the renal artery wall; multiple balloon inflations may result in increased vessel trauma.
  • The Paradise Catheter is for single use only.  Do not resterilize or reuse. Reuse, reprocessing, or resterilization will compromise device integrity which may result in patient injury, illness, or death.
  • Do not touch the Paradise Catheter balloon during sonication, as it may result in serious injury.
  • The Paradise System may interfere with or adversely affect the operation of cardiac pacemakers or other active implants, unless proper precautions have been taken or managed per the manufacturer’s instructions. When in doubt regarding possible hazards, seek qualified advice and/or consult with the manufacturer(s) prior to initiating a procedure.  The Paradise Catheter is a Type CF, defibrillation-proof Applied Part.
