A retrieval catheter (200) comprises a catheter shaft (2) and a retrieval catheter tip at the distal end of the shaft (2). The tip comprises an expandable tip body (201) and two reinforcement columns (6, 7) extending along the tip body (201) embedded within the tip body (201). The tip body (201) comprises a stiff, distal, radiopaque segment (203) and a soft, proximal segment (202). The distal segment (203) has a distal nose part (205) extending distally of the reinforcement columns (6, 7). Along the distal nose part (205), the wall thickness of the tip body (201) tapers distally from a smaller wall thickness to a larger wall thickness, and the internal diameter tapers distally from a larger diameter to a smaller diameter.
