Embodiment Construction

[0025] see figure 1 with figure 2 As shown, a steerable laser balloon catheter of the present invention includes a laser catheter 1 and a balloon catheter 2, the laser catheter 1 and the balloon catheter 2 are arranged in parallel from the head end to the tail end, and the balloon catheter The catheter 1 has a balloon 3, the head end of the laser catheter 1 exceeds the head end of the balloon catheter 2, and one end of the balloon catheter 2 is fixed to the wall of the laser catheter 1 at one end, and the fixed position is located at Before the balloon 3 of the balloon catheter 2; in this way, the catheter of the balloon 3 part forms a cross connection with the laser catheter 1. After the balloon 3 is inflated, the laser catheter 1 realizes the function of steering and windowing; the laser catheter 1 At least four laser fibers 11 are embedded in the tube wall at the head end, and the four laser fibers 11 extend all the way to the tail end of the laser catheter 1 .

Abstract

The invention provides an interventional therapy device realizing steering and positioning fenestration through a laser catheter. The interventional therapy device is characterized by comprising the laser catheter and a balloon catheter which are parallelly arranged from the head end to the tail end, the balloon catheter is provided with a balloon, the head end of the laser catheter exceeds that of the balloon catheter, one end of the balloon catheter is fixed to the catheter wall of one end of the laser catheter, the fixing position is positioned in front of the balloon of the balloon catheter, and at least four laser optical fibers are embedded in the catheter wall of the head end of the laser catheter and straightly extend to the tail end of the laser catheter. The invention further provides an interventional therapy device realizing steering and positioning fenestration through the laser catheter. Steering and positioning functions are realized through the laser catheter, and a fenestration function is realized; the laser catheter and the balloon catheter are combined for accurate positioning fenestration of artificial blood vessels of covered stents.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an interventional treatment device and method for realizing turning and positioning of windows through a laser catheter. Background technique [0002] The treatment of aortic dissection and thoracoabdominal aortic aneurysm has become more and more endoluminal. Simple B-type dissection and infrarenal type abdominal aortic aneurysm have been treated in the entire cavity; selective partial A-type dissection Endovascular treatment is also being attempted; thoracic aortic aneurysm, thoracoabdominal aortic aneurysm, and perirenal or suprarenal abdominal aortic aneurysm are also increasingly More use of intracavitary methods of treatment. Endovascular treatment of aortic dissection and aortic aneurysm has gradually become a popular choice for doctors and patients due to its minimal invasiveness, high efficiency, perioperative mortality rate, medium and long-term survival rate...
