Embodiment 1
[0022] The structure of the multi-balloon intravascular catheter in this embodiment is shown in Figure 1. One end of the tube body 1 is open, and the other end is equipped with a fixing sleeve 6. At the end close to the tube body opening, the outer wall of the tube body is coated and fixed with The first balloon 2, the second balloon 3, the third balloon 5, and the balloon air delivery tube 7 are three at a certain distance, inserted into the inner cavity of the tube body 1 through the fixing sleeve 6 and respectively connected to the corresponding inner cavity of the balloon. communicated; there are two side holes 4, which are opened between the second balloon 3 and the third balloon 5, and there is no side hole between the first balloon 2 and the second balloon 3; there is one blood vessel 8, It is inserted into the inner cavity of the tube body 1 through the fixing sleeve 6 and communicates with the holes 4 on both sides and the opening of the tube body 1 . Tube body 1, fix...
Embodiment 2
[0027] The structure of the multi-balloon intravascular catheter in this embodiment is shown in FIG. 2 . The difference from Embodiment 1 is that there is only one side hole 4 opened between the second balloon 3 and the third balloon 5 . The method of using the multi-balloon intravascular catheter with this structure is the same as that in Example 1.
Embodiment 3
[0029] The structure of the multi-balloon intravascular catheter in this embodiment is shown in Figure 3, and the difference from Embodiment 1 is that the side hole 4 is opened between the first balloon 2 and the second balloon 3 and the third balloon Between the balloon 5 and the fixed sleeve 6 and close to the third balloon, there is one side hole at both places, and there is no side hole between the second balloon 3 and the third balloon 5; the blood transfusion tube 8 is equipped with a stylet 9 , The stylet and the blood vessel are combined in a push-and-pull manner.
[0030] The multi-balloon intravascular catheter of this structure is also suitable for the operation of cardiovascular aneurysm involving the renal artery, and the usage method is as follows: insert the catheter from above, inflate the third balloon 5, and block the artery. The surgeon cuts off the diseased blood vessel, puts the artificial blood vessel outside the catheter, and first anastomoses the bilate...
