CARDIAC OCCLUDER Russian patent published in 2014 - IPC A61B17/122 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, and can be used for occlusion of opening in heart tissue with self-centring mechanism. Device includes two separate wires of definite shape, each of which being mirror reflection of respective other wire. Each wire forms semi-discs or quarters of disc, which together form distal and proximal discs. In other versions device includes four separate wires, each of which is a mirror reflection of adjacent wire and forms proximal and distal quarters of disc. In versions with four wires quarters of disc of each wire together form proximal and distal discs. Distal disc and proximal disc are separated with self-centring interception. Proximal disc is attached to bushing, which includes screw mechanism. Such bushing is not obligatory on distal disc. Discs additionally include overlay, forming seal for closing opening in tissue.

EFFECT: wires, which form discs, possess shape-memory ability, so that they can be compressed and deformed in catheter during delivery, but take and preserve given shape after delivery.
