Perfusion and dilation balloon system

Abstract

The invention discloses a perfusion and dilation balloon system. The perfusion and dilation balloon system comprises a perfusion and dilation balloon and a delivery conduit, wherein a perfusion chamber for pouring blood flow is arranged on the perfusion and dilation balloon; a closed balloon pressure chamber is formed by the infusion chamber and the perfusion and dilation balloon; a balloon wire guiding chamber is arranged in the balloon pressure chamber; a conduit pressure chamber communicated with the balloon pressure chamber is arranged in the delivery conduit; a conduit wire guiding chamber communicated with the balloon wire guiding chamber is arranged in the conduit pressure chamber. According to the perfusion and dilation balloon system disclosed by the invention, the balloon pressure chamber is filled with liquid with a certain pressure to dilate the perfusion and dilation balloon, thus forming a hollow cylindrical pipeline body; the hollow perfusion chamber guarantees the perfusion of the blood blow while blood vessel walls are supported and dilated by a balloon wall of the perfusion and dilation balloon; when serious lesion of blood vessel openings, aortic dissecting aneurysm and main blood vessel opening occur, effective blood flow perfusion channels can be effectively provided for important blood vessel opening parts and corresponding visceral organs, thereby guaranteeing further intervention and surgical treatment.

Description

technical field [0001] The invention relates to the technical field of medical intervention consumables, in particular to a perfusion and expansion balloon system. Background technique [0002] Vascular stenosis and occlusion are diseases with high morbidity and mortality. For vascular diseases, especially arteriosclerosis, stenosis and occlusion diseases, vascular lesion balloon dilatation and stent implantation are one of the main treatment methods. The expandable balloon is delivered to the lesion, and the diameter of the lumen of the vessel is enlarged by filling and expanding the balloon to squeeze the plaque outside the blood vessel, and finally, a stent is implanted in the lesion to support the lumen to achieve the purpose of treating vascular stenosis. [0003] In the case of vascular lesions in special clinical parts, such as spontaneous or iatrogenic aortic dissection involving the ostium of main branch arteries such as coronary arteries, renal arteries, and commo...

Problems solved by technology

[0004] At present, in addition to drugs to reduce myocardial oxygen consumption, stabilize plaque, inhibit platelet function, and monitoring methods, the above-mentioned patients with severe coronary ostium stenosis have no better treatment before undergoing coronary artery bypass grafting in cardiac surgery.
