a frame comprising interconnected struts forming vertices and defining a retrieval device lumen extending longitudinally through the frame and openings extending from an exterior of the frame to the lumen, the interconnected struts having portions that form parallel edges to define a gap on a proximal side of a corresponding one of the vertices and to allow the interconnected struts to move toward and away from each other to facilitate transition of the frame between the collapsed configuration and an expanded configuration; and
protruding features each extending from the frame on a distal side of the corresponding one of the vertices;

expanding the retrieval device outside of the delivery device;
engaging the thrombus with the retrieval device while in the expanded configuration, wherein engaging the thrombus comprises contacting the thrombus with the protruding features of the retrieval device, the protruding features extending radially inwardly from the frame; and
retracting the retrieval device toward the delivery device.
