The shunt catheter 100 is sleeved on a balloon segment of the protective balloon 200, and is placed at a blood vessel position affected by a lesion or requiring temporary blocking of a side wall or a branch blood flow, and the push tube 120 is filled with a contrast medium through the interface 300, so that the protective balloon 200 is filled to avoid bleeding, and meanwhile, the blood vessel continues to flow through the shunt tube 110, and the filling condition of the protective balloon 200 can be monitored through perspective or DSA images. The inside of the shunt tube 110 is used as a channel to maintain blood flow, the protective balloon 200 is sleeved on the outer wall of the shunt tube 110, hemostasis is achieved by filling the protective balloon 200, and the shunt device can be guided in place through a guide wire and an intermediate catheter, so that the shunt tube is suitable for operations with high protection requirements, such as neurosurgery and the like, and the operation is fine. And the operation is simple and convenient only by controlling the filling and discharging of the contrast agent by the protective balloon 200, and the problems of delay, complications, medicine use and the like in the later period are avoided without placing an extra implant.
As shown in fig. 1, the shunt tube 110 includes a tube portion 111 and a reinforcing portion 112, the reinforcing portion 112 is connected between the tube portion 111 and the push tube 120, and the protection balloon 200 is sleeved on the outer wall of the tube portion 111. By providing the reinforcement 112, the overall structural strength and push stability are improved.
Specifically, the tube 111 has a circular structure with a 360 ° arc, an area surrounded by an inner wall is used for blood to pass through, the reinforcement 112 is connected to a side wall of the tube 111 facing the interface 300, and the arc of the reinforcement 112 gradually decreases from the tube 111 to the interface 300.
More specifically, the pushing tube 120 is connected to the outer wall of the reinforced portion 112, with continued reference to fig. 1, since the radian of the reinforced portion 112 gradually decreases from the tube portion 111 to the interface 300, the width of the reinforced portion 112 gradually increases from top to bottom, and the pushing tube 120 is connected to the lower side of the reinforced portion 112, i.e. the contact area between the two is increased, so that the structural strength is further improved.
The area surrounded by the inner wall of the reinforcing portion 112 is communicated with the area surrounded by the tube portion 111, so that when the shunt tube 110 is placed in a blood vessel, the area surrounded by the inner wall of the reinforcing portion 112 and the area surrounded by the tube portion 111 serve as a blood flow channel. It can be seen that the vascular blood flow is ensured to be smooth while the structural strength is ensured.
As shown in fig. 1, the protective balloon 200 is sleeved on the outer wall of the shunt tube 110. The protective balloon 200 may be sleeved on the outer wall of the shunt tube 110 in an integrally formed or fastening manner.
The protecting balloon 200 is in a long cylindrical shape in a full state, the protecting balloon 200 has high compliance, can be fully expanded under lower pressure, conforms to the shape of a blood vessel, avoids damaging the intima of the blood vessel, causes vascular displacement, and can protect the wall of the blood vessel. In addition, the protective balloon 200 can be selected according to different lesions with different specifications, including diameter and length. Referring to fig. 1 and 2, the protective balloon 200 has a balloon 210 inside, and the push tube 120 communicates with the balloon 210 to inflate and deflate the balloon 210 with a contrast medium. By filling the protective balloon 200 to stop bleeding or block the blood flow of branches or lesions, it can be seen that the hemostasis is achieved by filling the protective balloon 200, and the blood flow through the tube portion 111 is maintained, so that compared with the prior art that the hemostasis needs to be blocked, the blood flow maintenance needs to be achieved by a transfer tube, and the smoothness of the blood flow of the main blood vessel is effectively ensured.
With continued reference to fig. 1, the diameter of the pushing tube 120 is much smaller than the diameter of the tube portion 111, and the pushing tube 120 is used for pushing, so that the thinner the pushing tube is, the better the pushing tube is under the condition of meeting the strength.
The length of the push tube 120 is much longer than the length of the tube portion 111. And the length of the push tube 120 meets the length requirement of being delivered via the femoral artery or radial artery to the site where protection of the blood vessel is desired.
Preferably, the protective balloon 200 in the inflated state protrudes outside the tube portion 111 and the push tube 120, respectively, and the protective balloon 200 directly contacts the vessel wall to exert a hemostatic effect.
As shown in fig. 1, the interface (Hub interface) 300 is connected to a pressurizing pump, a tee joint or a bayonet injector for filling the protecting balloon, and the protecting balloon 200 is filled under the action of the filling contrast agent mixture and can be monitored in real time under perspective or DSA. The protective balloon 200 and the interface 300 are respectively positioned at two ends of the device in the length direction.
The using method of the intracavity blood vessel protection and diversion device comprises the following steps:
in a first step, when treating tumors involving blood vessels or aneurysms emanating from the side walls of blood vessels, or even branch vessels of malformed blood vessels, during surgery, a vascular access (artery or vein) is established and the device is guided into place through a guide wire and an intermediate catheter, i.e. a protective balloon 200 of suitable length and diameter is pushed to be positioned at the segment of the blood vessel to be temporarily protected. The protective balloon 200 is exhausted and is connected with a booster pump, a tee joint or a bayonet injector for standby.
Second, the protective balloon 200 may be inflated to indicate when a need for protecting a blood vessel or a need for isolating a lesion for defining a morphology of a blood vessel is felt in a conventional procedure. If the aneurysm needs to be clamped and separated, the protecting balloon 200 can be filled to block the neck of the aneurysm; if the blood vessel is ruptured and bleeding occurs, the protective balloon 200 can be filled for hemostasis, and the ruptured blood vessel can be repaired. During filling of the protective balloon 200, normal blood flow is maintained through the shunt 110.
Thirdly, after the repair is completed, the device is withdrawn after the operation is finished, and the vascular puncture site is treated conventionally.
Reference may be made to the method of use of balloon Guiding catheters, which may be used to complete Guiding into place using conventional guidewire and intermediate catheter intussusception Guiding under relatively tortuous vascular access conditions such as intracranial vascular.
In summary, when the tumor surrounding or involving the blood vessel is resected, or the aneurysm emanating from the side wall of the blood vessel, or even the branch vessel of the blood supply vessel malformation, the device is placed at the position of the blood vessel involved in the lesion by means of the compound operation, and the protection balloon 200 is filled, so that the effects of protecting the blood vessel from blood flow, preventing bleeding and facilitating repair can be achieved. The diversion device can be guided in place through a guide wire and an intermediate catheter in an intravascular intervention mode, is suitable for neurosurgery and other operations with high protection requirements and fine operation, and has the value of balloon forming for pathological blood vessels with atherosclerosis or spasm stenosis. The method is perfectly matched with the compound operation, and solves the problems of great bleeding caused by affected blood vessels in the conventional operation or ischemia and thrombus caused by blood flow interruption when treating focus or repairing blood vessels.
