Medtronic plc posted solid fiscal year second-quarter results led by the cardiovascular business with 9.3% growth. The Affera Sphere-9 pulsed field ablation system tripled the company’s sales in the hot PFA segment and pushed the cardiac ablation solutions unit to 71% growth, a nice uptick from the nearly 50% seen in its Q1.
The U.S. CMS has confirmed that it will cover renal denervation as a treatment for hypertension in a final coverage memo that largely mirrors the July 2025 draft. One key difference, however, is that Medicare beneficiaries are eligible for RDN after only six weeks of optimized medical therapy, half the three-month waiting period described in the draft.
Medtronic plc’s SPYRAL HTN-ON MED trial demonstrated significantly greater reduction in blood pressure with the Symplicity Spyral renal denervation procedure at three years than a sham procedure in a study presented as featured clinical research at the 2025 Transcatheter Cardiovascular Therapeutics conference in San Francisco.
The renal denervation hypothesis of hypertension was initially viewed with some skepticism, and Dublin-based Medtronic plc. endured a major setback when clinical trial data failed to make a compelling case for approval for the Symplicity Spyral. However, the company finally landed an FDA approval for the device, opening the gates to a new and significant market opportunity even with competition already on the market.
Dublin-based Medtronic plc. has invested considerable resources into its renal denervation program, but the company has not completed its regulatory journey for the U.S. market just yet. Medtronic failed to persuade an FDA advisory committee of the virtues of its Symplicity Spyral device due to inconsistent results from the two major studies presented at the hearing but vowed to keep working on the application despite the sustained headwinds.
Medtronic plc has presented three-year data on its global, multicenter, blinded, randomized and sham-controlled renal denervation (RDN) clinical program Spyral HTN-ON MED during the late-breaking clinical trial session at EuroPCR on May 17. The trial enrolled 80 typical uncontrolled hypertensive patients, randomized to RDN or sham control.
As was the case with left atrial appendage closure, renal denervation (RD) as a treatment for hypertension has proven to be difficult to move along into routine clinical usage. New data for a study sponsored by Medtronic plc showed that RD offers a statistically significant improvement over sham treatment in reducing hypertension, but the data do not seem to suggest that patients will be able to drop their antihypertensive medications after RD treatment.
A new study has found that despite the risk, many patients are open to interventional procedures such as renal denervation (RDN) if it can lead to improved blood pressure. RDN is performed under local anesthetic and uses radio frequency ablation to burn the nerves in the renal arteries. The process causes a reduction in nerve activity, which decreases blood pressure.
Results of the pivotal Spyral-HTN OFF MED study presented at the American College of Cardiology's Annual Scientific Session on March 29 demonstrated significant reduction in blood pressure three months after renal denervation (RDN) in patients with unmedicated hypertension.
Years after a setback to its clinical program, Medtronic plc‘s Symplicity brand renal denervation (RDN) system appears to be firing on all pistons. The Dublin-based company said this week that it will begin enrolling patients in a pilot study to assess the safety and efficacy of its newer-generation Symplicity Spyral using a targeted procedural approach with fewer radiofrequency (RF) ablations.
