Embodiment 1

[0109] See attached Figure 4 , in this embodiment, the first balloon 1 and / or the second balloon 2 is a multi-chambered balloon 100 . The interior of the multi-chamber balloon 100 includes a first sub-chamber 101a and a second sub-chamber 101b that are independently separated from each other. The first sub-chamber 101a and the second sub-chamber 101b communicate with the first perfusion branch 102a and the second perfusion branch 102b respectively; the first perfusion branch 102a and the second perfusion branch 102b jointly One end of the main channel 103 joins, and the other end of the perfusion main channel 103 is connected to the perfusion liquid delivery pump 8 .

Embodiment 2

[0111] See attached Figure 5 , in this embodiment, the first balloon 1 and / or the second balloon 2 is a multi-chambered balloon 100 . The interior of the multi-chamber balloon 100 includes a first sub-chamber 101a, a second sub-chamber 101b and a third sub-chamber 101c which are independently separated from each other. The first subchamber 101a, the second subchamber 101b and the third subchamber 101c communicate with the first perfusion branch 102a, the second perfusion branch 102b and the third perfusion branch 102c respectively; The perfusion branch 102 a , the second perfusion branch 102 b and the third perfusion branch 102 c join together at one end of the perfusion main circuit 103 , and the other end of the perfusion main circuit 103 is connected to the perfusion liquid delivery pump 8 . The tail ends of the first subchamber 101a, the second subchamber 101b and the third subchamber 101c coincide; the head ends of the second subchamber 101b and the third subchamber 101...

Embodiment 3

[0113] See attached Image 6 , in this embodiment, the inside of the first balloon 1 and / or the second balloon 2 also includes a penetrating inner tube 9, the inner tube 9 is hollow, and the two ends are connected to the first balloon 1 respectively. And / or the external connection of the second balloon 2.

Abstract

The invention relates to the technical field of medical treatment, and relates to sacculus for a bifurcation lesion in a living body, application thereof and a surgical method, in particular to the sacculus of a human vessel bifurcation lesion and the application thereof. The sacculus includes first sacculus and second sacculus which are separately disposed. The drug-loaded sacculus has the following advantages that 1, the drug-loaded sacculus can play a greater role in a lesion portion; 2, in the treatment of the complex bifurcation lesion, the two drug-loaded sacculus is respectively placedin two branch vessels, and the expansion is simultaneously achieved; 3, corresponding fittings are used for modifying to greatly simplify the surgical treatment process and improve the prognosis of the disease treatment.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a balloon for treating bifurcation lesions of pipelines in living organisms, in particular to a balloon for treating bifurcation lesions of blood vessels in a human body, its use and an operation method. Background technique [0002] There are a large number of branch pipelines in the body, especially in the blood vessels, respiratory tract, digestive tract, ear canal, nasal cavity and other lumens in the human body. high incidence area. Interventional therapy using stents or balloons is one of the rapidly developing treatment methods. [0003] Coronary artery bifurcation lesions account for about 20-30% of the interventional treatment of coronary heart disease. It is a common clinical problem and one of the most challenging lesions in the field of coronary interventional treatment. The treatment of coronary bifurcation lesions is difficult, with low success rate, high complic...
