Overview of the 2023 FDA Circulatory System Devices Advisory Panel Meeting on the Symplicity Spyral Renal Denervation System

Abstract

Hypertension remains a leading preventable cause of myocardial infarction, stroke, kidney disease, and cardiovascular death worldwide. Despite lifestyle modifications and intensification of medical therapy, suboptimal blood pressure control is common, spurring the development of device-based therapies for hypertension. The US Food and Drug Administration (FDA) assembled the Circulatory System Devices Panel on August 22-23, 2023, to discuss the safety and effectiveness of renal denervation devices manufactured by Recor Medical and Medtronic. After reviewing the ultrasound-based Recor Paradise renal denervation system the day prior, the panel reconvened to discuss the radiofrequency-based Medtronic Symplicity Spyral Renal Denervation System. In this manuscript, we summarize the data presented by the sponsor and FDA and detail the deliberation and discussion during the meeting.
