FDA is looking forward to reviewing PMAs from several anti-hypertension devices in the coming years – including technologies from Medtronic, ReCor Medical, ROX Medical, and Vascular Dynamics – so the agency convened its Circulatory System Devices Panel on Dec. 5 to get recommendation on pre-market clinical trial design, post-approval study design, indications and labeling for such devices.
Medtronic looks to be back on track with its renal denervation plans, after announcing its Symplicity Spyral system got off to a good start with positive six-month results in the SPYRAL HTN-ON MED pilot study. The data, presented at EuroPCR 2018 in Paris, showed that Symplicity Spyral was able to reduce blood pressure significantly in hypertensive patients prescribed anti-hypertension medications, with no major adverse safety events out to six months.
FDA has granted an investigational device exemption for the SPYRAL HTN renal denervation global clinical trial program, designed to avoid the problems that led Medtronic's prior pivotal study to miss its endpoint.
