DEVICE, METHOD AND SYSTEM FOR VESSEL CLOSING Russian patent published in 2015 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to field of medical equipment, namely to implanted medical devices and methods, associated with them, in particular, to devices and methods for closing holes in vessel walls. Closing device for vessel contains supporting frame, capable of extending inside vessel, and closing membrane, at least, partially supported by extendable supporting frame. Supporting frame is located around closing membrane periphery. Device is configured with possibility of folding and unfolding along longitudinal axis, in fact, coinciding with vessel axis, and with possibility of intraluminal positioning, after extension of supporting frame inside vessel, closing membrane near place of puncture, made in vessel wall. Method of vessel closing includes introduction of closing device into vessel through place of puncture by means of cover, positioning and extension of supporting frame from folded configuration in, at least, partially unfolded configuration by means of its unfolding inside vessel along longitudinal axis, in fact, coinciding with vessel axis, providing in this way, at least, partial closing of puncture place with closing membrane. System for closing vessel puncture contains closing device, cover, made with possibility to accept closing device in folded configuration and facilitate introduction of closing device through puncture into vessel; and pusher-rod, made with possibility of passing closing device through cover.

EFFECT: group of inventions provides faster and more effective closing; reduces time and cost; requires only inconsiderable additional surgical manipulations by operator in the course of delivery.
