Embodiment Construction

[0024] see figure 1 and figure 2 As shown, a kind of steerable laser balloon catheter of the present invention comprises a laser catheter 1 and a balloon catheter 2, and the balloon catheter 2 is divided into two parts; the balloon catheter 21 of the first part has a ball The balloon 3, the tail end of the laser catheter 1 and the tail end of the first part of the balloon catheter 21 are connected with the head end of the second part of the balloon catheter 22; the head end of the laser catheter 1 exceeds the first part The head end of the balloon catheter 21, the balloon catheter 21 of the first part is fixed to the tube wall of the laser catheter 1; in the present invention, the way the balloon catheter 21 of the first part is fixed to the tube wall of the laser catheter 1 It is fixed by rivets 4, and in practical applications, it can also be fixed by coils, or other more ways. In this way, the catheter of the balloon 3 and the laser catheter 1 form a cross connection. Af...

Abstract

The invention provides a reversible laser balloon catheter which comprises a laser catheter and a balloon catheter. The balloon catheter is divided into two portions; a first portion of the balloon catheter is provided with a balloon, and the tail end of the laser catheter and the tail end of the first portion of the balloon catheter are connected with the head end of the second portion of the balloon catheter; the head end of the laser catheter goes beyond the head end of the first portion of the balloon catheter, and the first portion of the balloon catheter is fixed to the wall of the laser catheter; at least four laser fibers are embedded in the wall of the head end of the laser catheter and extend all along to the tail end of the second portion of the balloon catheter. The invention further provides a method for applying the reversible laser balloon catheter. The reversible laser balloon catheter and the method have the advantages that the laser catheter has reversing and positioning functions, and the reversible laser balloon catheter further has a fenestration function; the laser catheter and the balloon catheter are used jointly for carrying out accurate positioning and fenestration on artificial blood vessels of covered stents.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a steerable laser balloon catheter and a use method thereof. 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, and incidence of complications that are not inferior to or...
