FIELD: medicine.
SUBSTANCE: invention refers to medicine and can be used to trap and retain an object to be removed from the body. An extraction device comprises an extractor trap and a trap control assembly. The trap has proximal and distal portions and comprises a set of filaments. The filaments come out of the end of the proximal portion towards the distal portion and return to the proximal end to form the set of loops. When unfolded, the loops are meshed within the proximal portion, and are free and unmeshed in the distal portion. Fibre segments of the distal portion are arched in relation to the fibre segments of the proximal portion so that the compressed extractor trap forms a hollow cavity and comes out of the distal portion towards the proximal portion.
EFFECT: effective removal of the objects from the body passage, ease and safety.
