Abstract
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.
Claims23
A thrombectomy system, comprising:
- a first catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel;
- a second catheter, the first catheter configured to be slidably disposed within a lumen of the second catheter;
- a third catheter, the second catheter configured to be slidably disposed within a lumen of the third catheter;
- an electrode carried by the distal portion of the first catheter, the electrode configured to be electrically coupled to an extracorporeal power supply;
- and
- an interventional element configured to be delivered through a lumen of the first catheter, the interventional element comprising an expandable member configured to be electrically coupled to the extracorporeal power supply.
3 more elements
A system, comprising:
- an expandable thrombectomy device coupled to a distal end of an elongate shaft, the shaft configured to be electrically coupled to a first terminal of a power supply;
- and
- a first elongate tubular member configured to receive the shaft therethrough, the first tubular member having an electrode carried by a distal portion thereof and a conductive lead electrically coupled to the electrode, the conductive lead extending along a length of the first tubular member and configured to be electrically coupled to a second terminal of the power supply;
- a second elongate tubular member having a lumen configured to slidably receive the first tubular member therethrough;
- and
- a third elongate tubular member having a lumen configured to slidably receive the second tubular member therethrough.
