Claim 9:
10. A thrombectomy system, comprising:
a first catheter;
a second catheter configured to be slidably received through a lumen of the first catheter, wherein the second catheter is configured to apply negative pressure at a treatment site;
a third catheter configured to be slidably received through a lumen of the first catheter;
an elongated member configured to be slidably received through a lumen of the third catheter, the elongated member having a proximal end configured to be coupled to a power source and a distal end configured to be positioned within a blood vessel at or near a thrombus;
an electrode configured to be electrically coupled to the power source, wherein the electrode is carried by a distal portion of one of the first catheter, the second catheter, the third catheter, or the elongated member; and
an interventional element carried at the distal end of the elongated member, wherein the interventional element includes a first metallic material and a second metallic material disposed on the first metallic material along at least a portion of the interventional element, and wherein the power source is configured to deliver a current to the interventional element via the elongated member to positively charge the interventional element and promote adhesion of the thrombus thereto.
