Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0021] An embodiment of the present invention provides a device for intima fenestration, such as figure 1 and 2 As shown, the device includes a first sheath tube 1 and a second sheath tube 2 , wherein the terminal end of the first sheath tube 1 and the terminal end of the second sheath tube 2 are magnetically connected.

[0022] here, as figure 1 and 2 As shown in , the first sheath tube 1 and the second sheath tube 2 can be the same or different, and the first sheath tube 1 and the second sheath tube 2 can be cylindrical, or In other cylindrical structures, the sheath includes an end protruding into the artery and an outer end outside the human body when in use. When in use, the first sheath 1 is introduced from the femoral artery to the intima, and the second sheath 2 is...

Abstract

An embodiment of the invention discloses an inner membrane fenestration device. The device comprises a first sheath tube and a second sheath tube, wherein the tail ends of the first sheath tube and the second sheath tube are magnetically connected; thus, when the device is in use, the first sheath tube is introduced from a femoral artery to an inner membrane, the second sheath tube is introduced from a brachial artery to the inner membrane, and then the tail ends of the first sheath tube and the second sheath tube are magnetically connected, so that the tail ends of the first sheath tube and the second sheath tube are aligned to each other, and finally, fenestration is implemented, and therefore the problem of serious complications such as aortic puncture and the like caused by puncture into a blood vessel is avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for intima fenestration. Background technique [0002] The treatment of aortic dissection has developed by leaps and bounds, and the in-hospital mortality rate has continued to decline. However, about 30% of patients with aortic dissection are complicated with severe complications such as distal tissue blood supply disorders. , the death rate is high. Simply replacing diseased blood vessels with artificial blood vessels cannot completely alleviate the problem of vascular obstruction in the internal organs of the extremities caused by the collapse of the intimal dissection, and the operation is risky. With the advancement of diagnosis and treatment technology, intraluminal stents can block the entrance of dissection tears and expand the narrow true lumen. Intimal fenestration can open a window between the true and false lumens to relieve the pressure gradient between the true and fals...
