Directed Renal Denervation (dRDN)

The Symple Surgical microwave device is demonstrated within a protein albumin gel highlighting the “doughnut-shape” circumferential ablation zone created. While penetrating 6mm deep in to the protein gel, the test demonstrates the thermal protection of the vessel wall and the 1mm ring of the medial layer. Past the 6mm ablation zone there is a substantial drop-off in temperature, thereby limiting damage to the non-target perivascular structures.
