FIELD: medical equipment.
SUBSTANCE: group of inventions relates to a method and an apparatus for manufacturing a medical tubular object, such as a catheter, for insertion into a body passageway. Method comprises steps of extruding a tube by pushing tube material though an extrusion nozzle and cutting extruded tube at a predetermined length. Further, an initial part of extruded tube is advanced onto a tapered mandrel arranged adjacent extrusion nozzle such that a flared end is formed. After a predetermined length of extruded tube has been advanced onto tapered mandrel, tapered mandrel is moved away from extrusion nozzle to prevent that rest of extruded tube is expanded by tapered mandrel.
EFFECT: technical result attained by use of inventions consists in providing more effective process of making tubular articles for medical purposes with expanded end.
