Abstract
The invention relates to the technical field of medical devices, and in particular relates to a novel combined intracavitary isolation implant used for the treatment of ascending aortic dilatation diseases, which comprises a metal wire stent (1) and an artificial blood vessel (2) sutured or stuck on the inner side of the stent. The novel combined intracavitary isolation implant is characterized in that: the metal wire stent (1) is divided into the following two parts: a tubular part (11) and a protruding part (12); the tubular part is a Z-shaped stent with a coating and represents a curved bow which conforms to the physiological morphological characteristics of the ascending aorta, so that the stent can fit well with an arterial wall; the protruding part is a meshed naked stent with a spherical shape and can closely fit on the inner wall of the coronary sinus after being placed in the coronary sinus, so as to prevent the displacement of the coated stent of the tubular part. The combined intracavitary isolation implant has a simple structure, can effectively occlude the dissection tear of the ascending aorta or isolate the aneurysm in the ascending aorta, prevents the occurrence of blood internal leakage due to the looseness or displacement of the intravascular isolation implant, and ensures the blood supply to the coronary artery, the brachiocephalic trunk and other branch arteries.
Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of interior isolation implant of compound aorta lumen for the treatment of ascending aorta dilatancy disease.
Background technology
Ascending aorta dilatancy disease comprises ascending aorta interlayer and ascending aorta tumor.Dissection of aorta (aortic dissection, AD) be meant that the aorta inner wall section tears, blood in the aorta lumen enters aortic tunica media from the aortic tunica intima tearing port, film is torn separation in making, and along the expansion of aorta long axis direction, thereby a kind of pathological change in true and false two chambeies of formation aorta.Its main harm is, directly breaking or forming to break after the aneurysm of false chamber causes massive hemorrhage death, interrupted the blood confession of aorta important branch in the interlayer forming process, causes the severe ischemic afunction of important organ, causes severe complications or death.Aortic aneurysm (aorticaneurysm) is meant aorta wall part or diffusivity expansion.Main harm has the following aspects: 1. the tumor body breaks, and aneurysm tumor wall is constantly impacted by blood flow and expands attenuation gradually, and posterior tuberosity body breaks and causes the lethal massive hemorrhage; 2. mural thrombus forms, and the tumor body expands place's slow blood flow, forms eddy current, and is coarse as tumor wall inner face, then easily forms thrombosis, and thrombosis comes off and can cause thromboembolism; 3. tumor body compressing normal surrounding tissue organ can cause discomfort or other illness, causes dysphagia as the compressing esophagus, and the compressing trachea causes dyspnea, and the compressing recurrent laryngeal nerve causes hoarseness etc.Along with hypertension incidence of atherosclerosis rate raises, the aortic distensibility disease incidence significantly rises, and rejuvenation trend is arranged in recent years.
Carried out aortic distensibility disease endovascular graft at present, promptly adopted invasive methods, come closed sandwich cut or isolated aortic aneurysm by the intracavity implant of inserting straight pipe type or branching type in the lumen of vessels, thereby reach therapeutic purposes.Isolation implant is made up of tubular metal silk support and stitching or the artificial blood vessel that is bonded in the support inboard in the said lumen of vessels, tubular metal silk support surrounds straight tube shape by elastic metallic yarn and forms after Z-shaped folding, artificial blood vessel is made by the artificial blood vessel membrane material, the artificial blood vessel membrane material is generally terylene (polyethylene terephthalate, English name polyethylene terephthalate is called for short PET).To be loaded in the carrier after the isolation implant compression in the lumen of vessels during use, deliver to the aortic aneurysm place again with its release by carrier by distant place femoral artery or iliac artery, because the elastic force effect of wire rack mount reverts to straight tube-like automatically and is close to the aorta inwall, diseased region and blood flow are isolated, thereby reached therapeutic purposes.This method need not open operation, and simple and direct Wicresoft, determined curative effect have successfully been given treatment to large quantities of patients.
Yet, because ascending aorta is relatively shorter, and the coronary ostium of the oriented heart blood supply of near-end, the brachiocephalic trunk opening of oriented brain of far-end and right upper extremity blood supply, this morphologic feature limits the application of existing straight tube-like intracavity implant in the ascending aorta district, graft is difficult to firm grappling in ascending aorta district lumen of vessels, in case internal hemorrhage due to trauma will take place in loose shift, and the operation fall through.Thereby need develop a kind of novel intracavity implant system and solve this problem.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can firmly be anchored to the ascending aorta district, can effectively seal the interlayer breach or the isolated aneurysmal compound inner cavity insulation graft that is positioned at ascending aorta that are positioned at ascending aorta.
The present invention also is made up of wire rack mount and stitching or the artificial blood vessel that is bonded in the support inboard, it is characterized in that wire rack mount is divided into siphonata and bulge two parts, siphonata is the Z type support of overlay film, the same with existing straight tube-like intracavity implant, but siphonata is the corresponding bow action of physiology and appearance feature with ascending aorta, and support can be fitted with ductus arteriosus wall better.Bulge is netted bare bracket, is sphere shape, so that can be close to the coronary sinus inwall after inserting it in coronary sinus, prevents the overlay film frame displacement of siphonata.This shape and structure meets the form characteristics of human body ascending aorta district blood vessel, graft firmly can be anchored to the ascending aorta district, and the overlay film frame of siphonata is effectively sealed the interlayer breach of ascending aorta or the aneurysm of isolated ascending aorta.
During use, according to aortal position of pathological changes and corresponding tremulous pulse internal diameter, select the appropriate size model, the induction system of packing into after routinely isolation implant in the compound aorta lumen being compressed also is delivered to ascending aorta release, notes the bulge of wire rack mount is inserted in the coronary sinus.Isolation implant reverts to original state automatically and is close to the inwall of ascending aorta and coronary sinus respectively in the compound aorta lumen under the elastic force effect of wire rack mount, thereby reaches the purpose of rebuilding blood flow.
The present invention is simple in structure, can effectively seal the interlayer breach or the isolated aneurysm that is positioned at ascending aorta that are positioned at ascending aorta, prevent because of isolation implant loose shift in the lumen of vessels causes the generation of blood internal hemorrhage due to trauma, and ensure that the blood of branch's tremulous pulsies such as coronary artery, brachiocephalic trunk supplies.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
The specific embodiment
Now in conjunction with the accompanying drawings the present invention is described in detail.
The present invention is made up of wire rack mount 1 and the artificial blood vessel 2 of sewing up or be bonded in the support inboard, it is characterized in that wire rack mount 1 is divided into siphonata 11 and bulge 12 two parts, siphonata 11 is the Z type support of overlay film, the same with existing straight tube-like intracavity implant, but siphonata is the corresponding bow action of physiology and appearance feature with ascending aorta, and support can be fitted with ductus arteriosus wall better.Bulge 12 is netted bare bracket, is sphere shape, so that can be close to the coronary sinus inwall after inserting it in coronary sinus, prevents the overlay film frame displacement of siphonata.
The present invention can make different specifications and models as required.
