Abstract

Devices and methods for implanting prostheses capable of radial expanding in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. Also disclosed is an Endovascular aneurysm repair system.

技术领域 FIELD

本发明一般涉及把血管假体附着于天然血管,并且特别地涉及用于修复罹病和/或损伤了的血管段的方法和装置系统。 The present invention relates generally to vascular prosthesis attached to the native blood vessel, and in particular to repair diseased and / or damaged a method and device system for vessel segment.

技术背景 technical background

由受损伤或者罹病而削弱血管壁可以导致血管扩张并且形成血管瘤。 By a damaged or diseased vessel wall can result in weakened blood vessel dilation and hemangioma formation. 如不加治疗,血管瘤的大小可增长并且将最终破裂。 Such as untreated, the size of the hemangioma can grow and eventually rupture.

例如,主动脉血管瘤主要地发生在腹动脉区域, 一般地在肾动脉与主动脉叉之间的肾下区域。 For example, aortic aneurysms occur in the abdominal main artery region, generally infrarenal area between the renal arteries and the aortic fork. 动脉瘤也可发生在主动脉弓和肾动脉之间的胸部区域。 Aneurysms can also occur in the thoracic region between the aortic arch and renal arteries. 主动脉瘤破裂可造成大出血并且致死率高。 Aortic aneurysm can cause bleeding and death rate.

开放手术更换罹病的或者损伤的血管段可以降低血管破裂的风险。 Open surgery to replace damaged or diseased vessel segment can reduce the risk of vascular rupture. 在该手术中,切除罹病的或者损伤的血管段并且安装或以直的构形或以分杈的构形制造的假体移植物,然后用缝线永久地附着和密封在天然血管的末端上。 In this surgery, removal of diseased or damaged section of vessel and the installation configuration or in a straight or Forking configuration fabricated prosthetic grafts, and then permanently attached and sealed with sutures on the end of a native blood vessel . 这些手术用的假体移植物一般地是无支持的编织管并且典型地用聚合物,ePTFE或者其它适当的材料制造。 These surgical prosthetic grafts typically braided tube is unsupported and is typically a polymer, ePTFE or other suitable materials. 所述移植物纵向无支持从而它们可以适应血管瘤和天然血管的形态上的改变。 The graft longitudinally unsupported so they can accommodate changes in the morphology of native blood vessels and vascular tumors. 然而,这些手术需要大的手术切口并且致病率和死亡率高。 However, these procedures require a large surgical incision and the high morbidity and mortality. 另外, In addition,

许多患者由于其它复合发病(co morbidity)而不适于这种类型的大手术。 Since many patients the incidence of other composite (co morbidity) are not suitable for this type of major surgery.

引入了血管内动脉瘤修复以克服与开放手术修复相关联的问题。 The introduction of endovascular aneurysm repair in order to overcome the problems associated with open surgical repair. 动脉瘤用血管腔内安置的血管假体搭桥。 With a vascular aneurysm endovascular prosthesis placement of bypass. 典型地,这些动脉血管瘤假体移植物縮瘪地用导管经股动脉发放。 Typically, these arterial aneurysm prosthetic grafts deflated catheter through the femoral artery with a payment. 这些移植物一般地设计有附着在金属的支架(斯腾氏支架)结构的纤维材料,所述的金属支架膨胀或者被膨胀以接触血管的内径。 These grafts designs have generally adhered to the fiber material of the metal stent (stent Sternberg's) structure, or the expansion of the metal stent is expanded to contact the inner diameter of the blood vessel. 与开放手术动脉瘤修复不同,血管腔内布设的移植物不缝合在天然血管上,而是依赖于从支架伸出的在布设过程中穿入天然血管内的倒钩,或用支架本身的径向膨胀力把移植物固定在位。 Open surgery different artery aneurysm repair, endovascular grafts are not sutured laid on a natural blood vessel, but rely on penetration of barbs extending from the stent within the native vessel during emplacement, or stent diameter itself the expansion force to the graft in place. 与缝合比较时,这些移植物附着手段不提供相同的附着力度,并且可能在布设时损伤天然血管。 When compared to suturing, these grafts attached to attachment means do not provide the same strength, and can damage the native vessel upon laying.

因此,有这样的血管内动脉瘤修复系统的需要,所述的血管内动脉瘤修复系统首先提供可以适应血管瘤的形态改变并且可以不损伤天然血管地布设的假体移植物,其次提供一种将移植物永久性附着到血管壁的独立的血管内固附系统。 Accordingly, there is a need aneurysm repair system in such a vessel, said vascular aneurysm repair system can be adapted to provided first aspect of the hemangioma changed and prosthetic grafts can not damage the native vessel laid, secondly to provide a a separate vascular graft vessel wall permanently attached to a solid attachment system.
