The invention relates to a thrombectomy catheter (10) comprising a distal end (D) for at least partially removing thrombus from a blood vessel (4), said distal end being conceived to undergo displacement along the blood vessel, wherein said distal end comprises a lumen (3) being arranged for collecting thrombus (T) and having a cross-section which is alterable from a collapsed state (Sl) to an expanded state (S2), wherein during said displacement the cross-section of the lumen in the expanded state is self-adjustable for substantially matching local cross-sectional dimensions (Dl, D2, D3) of the blood vessel (4). The invention further related to a device comprising a thrombectomy catheter.
