Endovenous ablation mechanism with feedback control

摘要

A vessel occlusion system includes one or more ablation elements that, when activated, is configured for at least partially closing a vessel segment of a patient. The vessel occlusion system further includes a sensor assembly that is configured for generating feedback indicative of a state of closure of the vessel segment, and an automated longitudinal translator configured for longitudinally translating the one or more ablation elements based on the feedback from the sensor assembly. The one or more ablation elements may be associated with a catheter member that slides within the catheter sheath.
