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 Figure 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 present invention relates to the field of medical technology, and relates to a balloon for bifurcation lesions in biological vessels, the use thereof and a surgical method, and in particular to a balloon for bifurcation lesions in human body blood vessels and the use thereof. Said balloon comprises a first balloon and a second balloon provided in split type. The implementation of the drug-loaded balloon of the present invention has the following advantages: ① the drug-loaded balloon can play a greater role at lesion sites; ② the treatment of complex bifurcation lesions is achieved by respectively placing the two drug-loaded balloons in two branch blood vessels for simultaneous expansion, and ③ by means of the corresponding accessory modification, the realization of the surgical treatment process is greatly simplified, and the prognosis of disease treatment is improved.

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 and its application. 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 complication rate an...
