A multi-wire instrument has a distal functional section, in which a plurality of individual wires form a wire basket, wherein they are combined at a distal end and connected to one another by being joined directly to one another or to a distal terminating body while forming a respective predetermined breaking connection. A shaft section extends between the distal functional section and a proximal end region of the multi-wire instrument. The individual wires extend in one piece from their distal end to the proximal end region of the multi-wire instrument and the shaft section is formed by the individual wires, which are combined there and held together. The individual wires are twisted together in the entire shaft section up to the basket-forming functional section, wherein they merge from the twisted distal end of the shaft section with radial widening, and/or the individual wires are twisted together in a distal end region which adjoins the basket-forming functional section in a distal manner and in this case abut one another along this twisting.
