Companies Plan To Resume Renal Denervation Trials

Medtronic and Boston Scientific have announced plans to start phase 2 clinical trials this year for their updated renal denervation catheters. The once promising new technology is intended to treat hypertension unresponsive to drug therapy. The failure last year of Medtronic’s Symplicity HTN-3, the first large pivotal trial to rigorously test renal denervation, sent manufacturers back to their […]

New Device to Lower Resistant Hypertension Shows Early Promise

A novel implantable device appears to show early promise in the treatment of resistant hypertension. The “Coupler” device from ROX Medical is about the size of a paper clip and is delivered via a catheter to the upper thigh, where it creates an anastomosis between the distal external iliac vein and artery, thereby mechanically lowering […]

The Uncertain Future of Renal Denervation

Following the spectacular crash and burn of the SYMPLICITY HTN-3 trial at the American College of Cardiology (ACC) meeting two weeks ago, the future of renal denervation (RDN) — the once highly promising catheter technology that many thought would cure resistant hypertension — appears in doubt. Although the device has not been approved in the U.S. — and will not be approved […]

No Benefit Found in First Real Test of Renal Denervation

SYMPLICITY HTN-3, the eagerly awaited first rigorous test of renal denervation, shows that the real effect of the novel blood-pressure-lowering technology is dramatically lower than earlier expectations, which had been fueled by data from previous uncontrolled trials. Results of SYMPLICITY HTN-3 were presented at the American College of Cardiology conference in Washington, DC, and published simultaneously […]
