Radiofrequency wire-assisted recanalization of chronic venous stent occlusions

Venous in-stent reocclusion can result in recurrent obstructive symptoms. Occlusions that are recalcitrant to traditional crossing techniques are inaccessible to effective therapies. However, radiofrequency-assisted recanalization techniques can mitigate the risk of therapy failure and allow treatment of previously untreatable lesions. The feature of automatic disabling of the radiofrequency wire upon metal contact can be exploited to increase the safety of crossing by ensuring intraluminal traversal and avoidance of unintended perforation of adjacent structures.
