SPYRAL DYSTAL Clinical Study
The objective of this single arm interventional study is to determine if renal denervation performed in the distal main and first order branch renal arteries is as effective in reducing blood pressure as the procedural approach used in the SPYRAL HTN-OFF MED clinical study.
Stanford is currently not accepting patients for this trial.
