Abstract

This invention relates to a medical instrument for the removal of foreign bodies out of physiological channels, such as ureters, arteries, bronchi and suchlike, having a flexible tube 1 for insertion into the physiological channel involved, said tube having an operating element 5 at its operator end and an expandable, element 6 at its insertion end, said expandable element being affixed at one end to the end of the tube 1 and at the other end to the end 8 of a controlling cable 4 and which via the controlling cable 4 which passes through the tube and which is connected to the operating element can be expanded and collapsed. The expandable element comprises a tube section made of a woven fabric or a braided fabric, the threads of which are spaced one from the other and which take an approximately screwthread-like course when the element is in the collapsed state. After insertion into the physiological channel, the element is expanded, it remaining permeable to fluids, but bearing foreign bodies with it on removal. <IMAGE>
