Illustration demonstrating clot retrieval using the ONE-SEG technique with the EMBOTRAP III. The balloon of the guiding catheter with a balloon is inflated to preclude flow from the internal carotid artery beforehand. (A,B) When the aspiration catheter (AC) can be navigated to the M2, a 0.021-inch microcatheter is guided distally using a microguidewire into the occluded vessel. Subsequently, only the distal basket of the EMBOTRAP III is deployed, with fluoroscopy guidance to ensure deployment up to the second marker from the tip. Then, aspiration is started using the AC, followed by slowly pulling and retracting the EMBOTRAP III into the AC. (C–E) When the AC can be navigated only to the M1 distal, similar to the approach in (A,B), the distal basket of the EMBOTRAP III is deployed from the distal end of the clot. Subsequently, both the AC and the EMBOTRAP III are pulled linearly to the M1, followed by retracting the EMBOTRAP III into the AC.
