A kind of ascending aorta endoluminal isolation and transplantation device

Abstract

The invention provides an isolating transplanting device in the aorta ascendens cavity. The device is arranged in the aorta ascendens inner membrane cavity which has dissection of aorta to adjust the blood flow of the cracking holes of the dissection layer. The isolating transplanting devicein aorta ascendens cavity is a metal tubulous naked support rack, has a resetting adjustment part which is arranged in the inner membrane cavity of the dissection layer, and comprises multiple first Z-shape support rack rings which are parallelly and mutually connected through 2-5 first elastic metal rods. A anchor fixing part is arranged in an far end aortic arch cavity and upper end cavity of an aorta descendens which is communicated with the aortic arch cavity, and is connected with the far end of the resetting adjustment part through a second elastic metal rod. Multiple second Z-shape support rack rings are parallelly and mutually connected through 2-3 second elastic metal rods, wherein the wave number of each first Z-shape support rack ring is 10-24, the wave height is 2mm-10mm. The wave number of the of each second Z-shape support rack ring is 6-8, the wave height is 5mm-20mm. The gap between two adjacent first Z-shape support rack rings is -8mm-3mm. The gap between two adjacent Z-shape support rack rings is 1mm-20mm.

Description

technical field

[0001] The invention belongs to the field of medical devices, and in particular relates to an ascending aorta intraluminal isolation transplantation device specially suitable for ascending aorta dissection. Background technique

[0002] In recent years, the incidence of aortic dissection has increased significantly, and there is a trend of younger age. The so-called aortic dissection (AD) refers to a partial tear of the inner wall of the aorta. Axial expansion, thus forming a pathological change of true and false aortic lumens. The blood supply of important branches of the aorta is interrupted during the formation of the dissection, resulting in the loss of severe ischemic function of important organs, and even serious complications or death. In addition, the direct rupture of the false lumen or the rupture after the formation of an aneurysm may also cause Hemorrhage to death.

[0003] In response to this situation, endovascular exclusion of aortic dissect...

Embodiment Construction

[0023] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0024] figure 1 It is a structural schematic diagram of the ascending aorta endoluminal isolation graft device installed in the ascending aorta lumen in this embodiment; figure 2 It is a structural schematic diagram of the ascending aortic endoluminal isolation grafting device in the embodiment of the present invention.

[0025] Such as figure 1 and figure 2 As shown, the ascending aortic endoluminal isolation grafting device 10 is a metal tubular bare stent, which is used for minimally invasive treatment of ascending aortic dissection, and includes a reset adjusting part 11, an anchoring part 12, an auxiliary anchoring part 13 and a developing marking part 14.

[0026] The reset adjustment part 11 includes a plurality of first Z-shaped stent rings 111 and a first elastic metal rod 112 connecting two adjacent first Z-shaped stent ri...
