Problems solved by technology

There are some problems in using ordinary microcatheters to achieve local thrombolysis. When injecting thrombolytic drugs, the guide wire needs to be withdrawn and then injected with thrombolytic drugs. When changing the position of the catheter, the steel wire needs to be pushed again. It is difficult to send to the distal catheter lumen again, and there is no balloon expansion function

Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] figure 1 Shown is a schematic view of a rapid exchange reverse thrombolytic balloon catheter device in use when it is used in conjunction with the guide wire 9 . For ease of description, define: figure 1 The side where the Chinese medicine injection hole 1 is located is left, and the side where the second outlet hole 8 of the guide wire is located is right.

[0019] A rapid exchange reverse thrombolytic balloon catheter device according to the present invention comprises: a catheter body 4, a Y-shaped catheter connected to the left end of the catheter body 4, and a distal catheter connected to the right end of the catheter body 4. The drug injection cavity and th...

Abstract

The invention discloses a quick-switching reverse thrombolysis balloon catheter device comprising a drug injection passage, a balloon compression and decompression passage, and a guide wire passage; the passages are mutually independent and arranged side by side. Two ends of the drug injection passage are provided with a drug injection hole and a drug filling side hole respectively. Two ends of the balloon compression and decompression passage are provided with a balloon compression and decompression hole and a balloon respectively. The two ends of the guide wire passage are provided with a guide wire first outlet and a guide wire second outlet. The drug injection passage, the balloon compression and decompression passage and the guide wire passage are integrated to one catheter, the functions of injecting drug, expanding the blood vessel and moving the device are achieved with one catheter by single puncturing, the expanded balloon can further function in blocking blood flow, thrombolytic drug that is injected is prevented from being flowed away by the blood flow, and thrombolytic effect is guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for performing local precise thrombolysis in coronary arteries during interventional treatment of thrombosis occlusion in acute myocardial infarction, specifically a rapid exchange reverse thrombolysis balloon catheter device. Background technique [0002] Acute myocardial infarction is a process in which, on the basis of coronary atherosclerotic stenosis, plaque rupture leads to rapid formation of local thrombus, and complete blockage of the lumen leads to ischemic necrosis of the myocardium at the vascular innervation site. Opening the infarction-related vessels as soon as possible is the most effective way to save the ischemic myocardium. The effective treatment of a large number of soft thrombus in the coronary artery is one of the main problems in the treatment of acute myocardial infarction. When the interventional therapy is performed, the balloon is directly expan...
