Abstract

A multiwire unit having a plurality of wire sections which are formed in one piece from a tubular piece whose tubular jacket is subdivided in at least an axial subsection by a plurality of axial slots. The wire pieces remain interlinked at a front end section at a distance to a front tube face, and assume a bent functional state downstream of the wire linking area in a defined functional state of the multiwire unit. The front wire linking area, in the functional state of the multiwire unit, is shaped to an essentially tipless front end closure. For this purpose, the axial slots end at an appropriate small axial distance to the front tube face. The multiwire unit may be formed as, for example, a wire basket unit or a wire filter unit for medical instruments.
