A
catheter (1) and
vein repair method that enables
vein repair surgeries without any bleeding and without hindering
blood flow in veins through bypassing the
blood flow in the
vein to be operated and by preventing any diseases arisen due to stop of
blood flow of the organ fed by the associated vein and that sustains blood flow by means of vein bypass in the course of vascular surgeries implemented for surgical processes related to veins in
human body and that comprises one
balloon (3) on each point close to its both ends, protective layer (4) positioned on the balloons (3); second path (5) enabling deflation inflation of the balloons (3), having monolithic
pipe shape adhered to the first path (2) side by side, whose one open end terminates within the
balloon (3);
check valve apparatus (7) that is monolithic with back end of the second path (5) and provides substances such as air and liquid with the
injector for inflation deflation of the
balloon (3); protective segment (6) surrounding externally the first path (2) and second path (5), thus preventing their blockage when compressed, that may have various lengths from back end of the balloon (3) to the backside of the
catheter (1), that is monolithic along with the first path (2) and the second path (5); cover (8) that prevents the
catheter apparatus (1) going out of the vein or its movement, that is located on body side of the catheter apparatus (1), positioned on back of the balloon (3), that can be moved over the catheter apparatus (1) as it is wider than body of the catheter apparatus (1), that has flexible structure having both ends open, that can have the shape of funnel or circle or ellipsis or different shapes; clamping apparatus (9) used to fix the cover on its relevant location; at least one third path (10) in the shape of
pipe with both ends open, whose one end is positioned within first path (2), other end is located out of first path (2) and used to draw the liquid or air; connection apparatus (11) that is integrated with outer back end of third path (10) and that enables connection with the external
injector and the catheters.
