Abstract: A stiffening device is disclosed that is adapted to cooperate with a flexible kidney stone extractor. The stiffening device includes a tube having a lumen sized to receive a part of flexible kidney stone extractor; a diversion member having a channel that is configured to receive a part of the flexible kidney stone extractor; and a connector coupled between the tube and the diversion member. The connector allows the channel of the diversion member to communicate with the lumen of the tube. A proximal portion of the connector is connected to the diversion member and a distal portion of the connector is connected to the tube.

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.

Abstract: A wire basket includes a fixing disc element coupled with several wire strands. The wire strands extend between a front end of the wire basket and a rear end of the wire basket to define an orbital shape. The fixing disc element forms a front closure of the wire basket and has at least first and second through-openings. A first of the wire strands is formed from a first wire segment that is looped through the first of the through-openings of the fixing disc element along a path extending from the rear end of the wire basket forward through the fixing disc element to form a U-shaped deflection that is looped through a separate second of the through-openings of the fixing disc element along a path extending from the fixing disc element to the rear end of the wire basket.

Abstract: The invention relates to a wire basket unit with a balloon-shaped wire basket composed of several wire strands (2a, 2b, 2d, 2e) which extend between a front end of the wire basket and a rear end of the wire basket and are formed from one or more wire segments, and with a fixing disc element (13a) on which the wire strands are fixed at the front end of the wire basket so as to form a front closure of the wire basket, wherein the fixing disc element has at least a first through-opening (14a) and a second through-opening (14b). According to the invention, at least a first (2a) of the wire strands is formed from a first wire segment which is looped through a first (14a) of the through-openings of the fixing disc element from the rear forwards and, forming a U-shaped deflection (2c), is looped through a second (14b) of the through-openings of the fixing disc element from the front to the rear again and is thus fixed on the fixing disc element. Use, for example, for medical basket instruments for retrieving stones.
