As renal denervation (RDN) makes a comeback for treatment-resistant hypertension, Deepqure Inc. is advancing its RDN medical device dubbed Hyperqure with the U.S. FDA granting clearance for a U.S.-based study.

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.
