## Abstract

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.

## Claims

### Claim 1

A catheter apparatus (1) maintaining blood flow by vein bypass, made of a plastic and similar raw materials, that is open on both ends, characterized in that the catheter apparatus comprises:
a first path connecting both ends,
one balloon (3) on a point close to each of both ends,
a protective layer (4) positioned on each of the balloons (3),
a second path (5) enabling deflation and inflation of the balloons (3), having a monolithic pipe shape adhered side by side to the first path (2), whose one open end terminates within the balloon (3),
a check valve apparatus (7) that is monolithic with a back end of the second path (5) and provides substances such as air and liquid with an external injector for inflation and deflation of the balloon (3),
a protective segment (6) surrounding externally the first path (2) and second path (5), thus preventing blockage of the first path and second path when compressed, the protective segment configured to have various lengths from a back end of the balloon (3) to a backside of the catheter (1), and is monolithic along with the first path (2) and the second path (5),
a cover (8) that prevents the catheter apparatus (1) from going out of the vein or movement of the catheter apparatus, that is located on a body side of the catheter apparatus (1), positioned on the back of the balloon (3), that can be moved over the catheter apparatus (1) as it is wider than a width of the body of the catheter apparatus (1), that has a flexible structure having both ends open, configured to have a shape of a funnel or a circle or an ellipsis or different shapes,
a clamping apparatus (9) used to fix the cover on a relevant location,
at least a third path (10) in the shape of a pipe with both ends open, having one end positioned within the first path (2), another end located out of the first path (2) and used to draw the liquid or air,
a connection apparatus (11) that is integrated with an outer back end of the third path (10) and that enables connection with the external injector and catheters.

### Claim 2 (depends on 1)

The catheter apparatus (1) according to claim 1, characterized in that the cover (8) and clamping apparatus (9) are integrated to each other or have a monolithic structure.
