1. A device for performing a thrombectomy, comprising:
a catheter extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough;
a grasper mountable over the distal end of the catheter, the grasper including first and second jaws connected to one another such that the first and second jaws are movable between an open configuration, in which the first and second jaws extend about opposing portions of the distal end of the catheter and are separated from one another to be configured to receive a portion of a thrombus therebetween, and a closed configuration, in which the first and second jaws are configured to be moved toward one another to grasp the portion of thrombus therebetween and separate a grasped portion of thrombus from a remaining portion of the thrombus;
a first control member connected to the grasper so that a longitudinal movement of the first control member relative to the catheter moves the grasper between the open and closed configurations; and
a proximal interface including a piston connected to the proximal end of the catheter so that, when the grasper is moved toward the closed configuration, the piston is configured to apply a negative pressure through the catheter to draw a separated portion of thrombus proximally therethrough.
