Embodiment Construction

[0033] Such as Figure 1-5 As shown, the present invention discloses a branched aortic artificial stent delivery device, which includes a transporter 100 , an artificial stent 200 disposed in the transporter 100 , and a catcher for matching the transporter 100 .

[0034] Wherein, the artificial stent 200 includes an aortic stent 210 and at least one branch arterial stent, the aortic stent 210 includes a stent body 211 and a film 212 sutured on the stent body 211, the film 212 is provided with a branch connection Area 230, the branch connection area 230 is seamless with the membrane 212; the branch arterial stent is connected to the branch connection area 230 of the membrane 212, the branch connection area 230 is provided with a folded portion, and the folded portion is located at Periphery of the branch artery stent.

[0035] The delivery device 100 includes an outer tube 110, an inner tube 130, a soft sheath 120, a main body guide wire 150 and a branch guide wire, the soft s...

Abstract

The invention relates to a branch type aorta artificial stent conveying device. The branch type aorta artificial stent conveying device comprises a conveyor, an artificial stent arranged in the conveyor and a catcher used for cooperating with the conveyor. The catcher is guided into branch arterial blood vessel, the conveyor is guided into the focus position of the aorta, then a soft sheath is fixed, an outer tube is gradually withdrawn to expose branch guide wires, then the catcher is used for catching the branch guide wires, and therefore, branch arterial stents are guided into the branch arterial blood vessel through the branch guide wires. In the surgical operation process, due to the fact that the branch guide wires are not reserved on the aorta in advance, the phenomena of crossing and winding of the guide wires cannot occur, the surgical operation difficulty is reduced, the surgical operation is simpler, the surgical time is shortened, and the surgical risk is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a branched aortic artificial stent delivery device. Background technique [0002] Aortic aneurysm and aortic dissection are aortic lesions that seriously threaten the life of patients. If not treated in time, the aortic aneurysm will increase in size, leading to rupture and death; aortic dissection may rupture and cause death. Ischemia of the kidneys, limbs and other organs and serious complications, such as cerebral infarction, paraplegia, acute liver and kidney damage, lower limb dysfunction, etc. In some cases, aortic aneurysms and aortic dissections require emergency surgery. [0003] With the development of endovascular technology, Thoracic EndovascualrAortic Repair (TEVAR) has become the main method for the treatment of some thoracic aortic aneurysms and aortic dissection. It puts a stent in the thoracic aorta, isolates the aortic lesion from the stent, and restricts the b...
