FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, namely to implantable device. Implantable device for application in human and/or animal body aimed at closing or partial closing openings of defects, cavities, canals, ducts in organs, etc. or creation of specified connecting opening between walls, organs, cavities, etc., has bearing structure. Primary form of bearing structure has larger ratio of length to transverse dimension along axis, and secondary form - smaller ratio of length to transverse dimension along axis. Bearing structure includes proximal section and distal section and has form of lattice and/or cloth and/or canvas and/or mesh. At least one section in secondary form contains two parts, one of which is the first to extend from primary form into secondary form and folds in direction from the other section onto the second part, directed towards said other section. Folded part folds back inside implanted device. Said device is used as vessel filter and/or device for removal of foreign particles, or as stent.
EFFECT: invention is suitable for implantation even in those places of human and/or animal body, in which only limited space is accessible for implantation, for instance, into left atrium of the heart, it also has good resistance to undesirable displacement after implantation.
