摘要： A device (1), e.g. an intravascular device, for removing an element, e.g. vascular occluding element (33), from within a lumen, e.g. a vascular lumen of a patient is described, comprising a tubular catheter body (4) made of a flexible material, with a proximal end (3), which in use is located outside of the body of the patient, and a distal end (2), which in use is located in the or at the lumen of the patient, and with a central duct (40) through which further devices (7, 14, 35) can be guided to the lumen of the patient from the outside of the patient, wherein the tubular catheter body (4) comprises a distal expansion area (25), which expansion area (25) has a contracted or folded state (26) in which the outside diameter of the expansion area (25) is substantially equal to the outside diameter of the tubular catheter body (4), and which expansion area (25) can be brought into a stiff expanded state (27) in the or at the lumen of the patient, wherein the expanded state (27) comprises an at least partially conical portion opening towards the distal end, such that an occluding element (33) can be drawn into the expansion area (25) in its expanded state (27). Such a device may be used for removal of an occluding implant which had been positioned incorrectly before or which had moved. Furthermore methods for making such a device (1) are disclosed as well as methods for using such adevice.
