Use of magnetic guidewire navigation in the treatment of lower extremity peripheral vascular disease: Report of the first human clinical experience

Abstract

The use of a magnetic navigation system (MNS) to facilitate catheter placement in electrophysiologic procedures has been increasingly documented over the past decade. Recently, the utilization of MNS to aid guidewire directionality in complex coronary lesions has also been described. Given the multifaceted ability of MNS to be applied to varying vascular beds, we describe the successful employment of this modality to facilitate treatment of lower extremity peripheral arterial disease in a symptomatic male with gangrenous toe ulceration.

Clinical applications of robotic technology in vascular and endovascular surgery

“…12,39 A case of successful use of the Niobe magnetic navigation system for the endovascular treatment of peripheral arterial disease in a symptomatic male with gangrenous toe ulceration has been reported. 39 From our unit, following experiments in in vitro silicon models and animal studies, a robotic-assisted endovascular aneurysm repair was accomplished in a 78-year old man with a 5.9-cm infrarenal AAA. 12 The robotic catheter was used to navigate within the aneurysm sac and access the contralateral limb of the bifurcated stent graft.…”

Robotic system-assisted endovascular treatment of a dissection-related pseudoaneurysm of the celiac axis secondary to fibromuscular dysplasia

“…16,17 Although clear indications for the applications of robotic technology have yet to be defined in the endovascular arena, several articles have documented its clinical use for navigation of tortuous anatomy and catheterization of challenging vessels that may be difficult with manual techniques in the aorta and periphery. [18][19][20] Presently, there is a 10F and 9F robotic catheter system with a coaxial 5F "leader" catheter as well as a 6F system. Nevertheless, the 9F and 10F systems require larger vascular access to then allow the delivery of 6F and 7F devices through the robotic catheters, respectively.…”

Robotic Percutaneous Coronary Intervention in Coronary Heart Disease: Applications and Recent Advances

“…Stereoaxis, in the United States, developed the Niobe magnetic navigation robot system in 2002, on the basis of the earliest research on vascular intervention robots. This system uses active catheter technology driven by magnetic navigation, which can decrease the difficulty of catheter passage through tortuous regions of blood vessels and shorten the time required for catheter placement in bifurcated blood vessels [7][8][9]. In 2019, Stereoaxis developed the Genesis RMN magnetic navigation cardiac ablation robot system based on the Niobe system.…”
