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.

Roseville, Calif.-based US Kidney Research Corp., formerly Curion Research Corp., has been working on its waterless renal replacement technology since its inception in June 2015. Its latest research efforts using its novel blood purifying technology have led to the production of the first ‘synthetic urine,’ which mimics the body’s natural production and the kidney’s filtration capability.
