Abstract

A medical device configured to retrieve calcified stones from the human body includes wire segments and a fixing disc element coupled with the wire segments. The wire segments form a wire basket. The fixing disc element is coupled with the wire segments at a front end of the wire basket. Multiple adjacent wire strands are formed from a first of the wire segments that is directed along a path extending from the rear end of the wire basket forward through a first through-opening of the fixing disc element, and looped through a second through-opening of the fixing disc element, and directed along a path extending from the fixing disc element rearward to the rear end of the wire basket to thus form a first U-shaped deflection disposed on a distal side of the fixing disc element at the front end of the wire basket.
