Claim 0:
1. A method of removing a thrombus from a body lumen, the method comprising:
inserting a device into the body lumen, the device including:
a catheter member;
a thrombus capture body at a distal-most end of the catheter member;
a macerator disposed more distally within the thrombus capture body than an extractor disposed within the thrombus capture body;
a biasing element configured to bias the thrombus capture body towards an expanded orientation; and
a thrombus blocking body disposed on the catheter member proximally from the thrombus capture body;

while maintaining the thrombus capture body in a contracted orientation in the body lumen, advancing the thrombus capture body distally of the thrombus;
maintaining the thrombus blocking body in a contracted orientation proximally of the thrombus;
deploying the thrombus blocking body from the contracted orientation to an expanded orientation;
deploying the thrombus capture body from the contracted orientation to the expanded orientation, whereby a circumferential edge of the thrombus capture body contacts a wall of the body lumen;
moving the thrombus capture body proximally towards the thrombus blocking body, while the thrombus blocking body is stationary relative to the proximally moving thrombus capture body, with the thrombus therebetween;
while maintaining the thrombus blocking body stationary, the thrombus blocking body biases the thrombus into the thrombus capture body as the thrombus capture body moves towards the thrombus blocking body, whereby the biasing element causes the circumferential edge of the thrombus capture body to apply a radial force against the wall of the body lumen; and
during the moving of the thrombus capture body proximally, actuating both the macerator and the extractor, whereby the thrombus is broken up by the macerator and removed from the body lumen via the extractor.
