Patent number: 11950794Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal power supply.Type: GrantFiled: October 11, 2021Date of Patent: April 9, 2024Assignee: COVIDIEN LPInventors: Hoai (Kevin) Nguyen, Gaurav Girdhar, Andyanhdzung Huynh
