In an extraction device ( 1 ) for extracting objects ( 2 ), in particular clots, foreign bodies, etc., from cavities ( 3 ) in a human or animal body, with first and second compressible and expandable collecting baskets ( 10, 20, 102, 110 ) between which the object ( 2 ) can be captured, said collecting baskets being mutually displaceable and being able to be drawn one into the other, at least one collecting basket ( 10 ) is umbrella-like in the expanded state and is designed with flexible wire-like adjustment elements for deliberately changing the shape and/or position of the collecting basket so that the object can be captured in the latter and can be drawn into the other collecting basket ( 20 ). |
