Symplicity Spyral to Treat Refractory Hypertension
September 28, 2021 | Technology Forecasts
Symplicity Spyral is a catheter-based device intended to ablate the sympathetic nerves that line the main renal arteries connecting the kidneys to the aorta.
Deactivating the renal sympathetic nerves purportedly can help reduce difficult-to-manage high blood pressure (ie, hypertension). An interventional procedure would shift care from standard office-based medical management for most patients with uncontrolled high blood pressure.
A physician inserts the helical ablation catheter into the femoral artery in the groin and advances it into the left and right renal arteries, alternately, to deliver radiofrequency energy in a spiral pattern, about 1 minute per application, to one or more sections of each artery. The physician removes the catheter using standard interventional techniques after treating both renal arteries. ...
