DEVICE FOR EMBOLIC OCCLUSION EXTRACTION Russian patent published in 2016 - IPC A61F2/01 A61F2/91 A61F2/915 A61F2/82 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely, to treating devices for vascular system and other channels in a human body, in particular to devices for embolic occlusion extraction. Device for embolic occlusion extraction comprises an elongated self-expanding unit having radially expanded configuration and radially unexpanded configuration. Expanding unit includes several overall longitudinal wave-like elements. Adjacent wave-like elements are connected to each other in a way to make several diagonally located structures in the form of cells. Expanding element comprises a proximal end part and a cylindrical part in of the main body. Cell structures in the cylindrical part of the main body are located circumferentially around the longitudinal axis of the expanding unit and cell structures of the proximal end part are located along part of the circle around the longitudinal axis of the expanding unit. Cell structures of the cylindrical part of the main body comprise proximal and distal flexible elements connected to each other by a pair of braces passing diagonally and spaced apart circumferentially. Each of proximal and distal flexible elements has a short post and a long post. At least some diagonally passing and spaced circumferentially braces contain one or several wires or bands, wound around them. Long posts of proximal and distal flexible elements do not contain or almost do not contain wire or bands wound around them.

EFFECT: device for embolic occlusion extraction is proposed.
