OCCLUSIVE DEVICE FOR VASCULAR SURGERY Russian patent published in 2015 - IPC A61B17/00 A61M25/08 

FIELD: medicine.

SUBSTANCE: group of inventions relats to medicine, namely to vascular surgery, and can be used in performing endovascular surgery, such as embolisation of blood vessels, treatment of arteriovenous defects or small aneurisms, and arterial laminations. For this purpose two versions of device for introduction of surgical glue on operation site of patient's body are used. In one version device, containing duct, which has input opening and output opening for surgical glue, is used. Device is made with possibility of travel in biological medium in patient's body from opening in patient's skin plane to operation site in such a way that immediately after duct reaches operation site, output opening is on operation site, with output opening remaining outside of said opening in skin plane. In the process of device application input opening is hydraulically connected with source of surgical glue and with pumping means, made with possibility of their control by operator. Device contains means for preventing contact between liquids, connected with duct and made with possibility of preventing penetration of blood or other biological material on operation site into duct and interaction with surgical glue. Second version of device contains duct and sliding connecting means, adjusted for connection of duct with needle-catheter. Duct has output opening and is adjusted for delivering dose of surgical glue and introduction of said dose through output opening on operation site at specified distance from skin plane hear operation site. Device also contains blocking means for blocking movement of duct relative to needle-catheter, made as one piece with duct and located at distance from output opening in such a way that output opening is located at said specified distance from skin plane, when blocking means rest against skin plane.

EFFECT: group of inventions provides occlusion of place of needle-catheter introduction, preventing haemorrhage, as well as provide possibility of realisation of endovascular surgery without changing properties of fast hardening of liquid due to prevention of contact of glue with biological fluids in the course of surgery.
