FIELD: medicine.
SUBSTANCE: invention relates to medical technology, namely to a magnetic navigation catheter system for the creation of endovascular intervascular anastomosis. System comprises two catheters with end magnets. System includes a cutting element arranged in the first catheter with the possibility of longitudinal movement. System has two conductor catheters and a flexible tubular pusher with a butt sleeve-type stop for moving the stent graft along the cutting element. Cutting element is made in the form of a flexible guide needle with radiopaque coating. Second catheter is provided with a flexible needle guide holder, made in the form of a basket-trap made of wire filaments with connected ends. End magnets have an antithrombotic ceramic coating and are connected to the catheters with the possibility of turn or bend.
EFFECT: technical result consists in the possibility of optimal positioning of future anastomosis with minimal traumatic intervention by obtaining the possibility of lateral aiming to create an intervascular axis, taking into account the anatomical features of the connected vessel.
