Solids trap cup for endoscopic removal of biliary, gland, renal and bladder stones or other concrements from human body, has culmination arch of wire loops with flattened cross section in cross-over contact areas of wire loops

摘要

The solids trap cup has a culmination arch of wire loops (4,5) with a flattened cross section in cross-over contact areas of wire loops. The longer cross-sectional axis of wire loops correspond to a bending axis of the respective culmination arch when retracting or pushing the wire loops from a catheter tube (9), or runs parallel to the bending axis.
