Abstract
A stone catching instrument for use, for example, as a stone catching basket and a wire filter unit for medical instruments, and method for producing the same, are provided. The stone catching basket instrument has a multiwire basket unit with several wire sections connected with one another as a cohesive wire complex, the wire complex cut in one piece out of a planar material in a rosette-shape and bent to form the wire basket unit. The wire sections extend essentially radially and are cohesive with one another at their inner radial ends at a wire linkage area. The wire basket unit when in a widened condition is arranged to catch particles caught through spaces between the wire sections, and when moved to a drawn-together condition, holds particles in the wire basket unit.
