Description

主动脉覆膜支架 Aortic stent graft

技术领域 FIELD

[0001] 本实用新型涉及医疗器械,尤其涉及一种主动脉覆膜支架。 [0001] The present invention relates to medical devices, particularly to an aortic stent graft.

背景技术 Background technique

[0002] 本实用新型中,术语“远端”指沿血流方向远离心脏的一端,“近端”指沿血流方向靠近心脏的一端。 [0002] In the present invention, the term "distal" refers to the end remote from the direction of blood flow in the heart, "proximal" means in the direction of blood flow near one end of the heart.

[0003] 主动脉瘤指主动脉壁局部或弥漫性的异常扩张,压迫周围器官而引起症状,瘤状破裂为其主要危险。 [0003] aortic aneurysm refers to the aortic wall abnormalities localized or diffuse expansion, oppression surrounding organs and cause symptoms, tumor-like rupture of its major risk. 常发生在升主动脉、主动脉弓、胸部降主动脉、胸腹主动脉和腹主动脉。 Often it occurs in the ascending aorta, aortic arch, descending thoracic aorta, abdominal aorta and abdominal aorta. 传统的手术治疗方法为开胸、开腹行病变主动脉切除人工血管置换术,手术风险大,而且多数病变根本不能手术,手术病死率高,易引起心、脑、肾功能不全等严重病发症。 The traditional surgical treatment for thoracic, abdominal aortic lesion was excised graft replacement, surgical risk, and most lesions can not surgery, high surgical mortality, can lead to heart, brain, kidney failure and other serious disease disease. 20世纪90年代以后,自从人体腹主动脉瘤腔内隔绝术出现,它就很快成为主动脉瘤的首选治疗方法。 After the 1990s, since the human abdominal aortic aneurysm endovascular exclusion occurs, it will soon become the treatment of choice for aortic aneurysm.

[0004] 主动脉瘤腔内隔绝术就是先对主动脉瘤患者进行CT动脉造影等影像学检查,获得主动脉瘤的精确数据,然后据此选择或定制口径和长度适合的主动脉覆膜支架。 [0004] Aortic endovascular exclusion of patients with aortic aneurysm is to be CT angiography and other imaging studies, accurate data is obtained aortic aneurysms, and selected accordingly suitable length and diameter or custom aortic stent graft . 手术时,在腹股沟部位做3cm长的小切ロ,在X线透视监视下,通过相应的输送系统经股动脉将支架送到病变主动脉部位,然后将支架从导管内释放。 Surgery, in the groin area did ro 3cm long small cut in the X-ray monitoring, the femoral artery to diseased aortic stent portion through a respective delivery system and then release the stent from the catheter. 释放后的主动脉覆膜支架张开至原来ロ径,并在支架本身弾力作用下,贴附在主动脉管壁上覆盖住主动脉病变部分,覆膜在病变血管中制造出新的血液通道,阻断其获得新鮮血液供应,使主动脉瘤逐渐形成血栓,从而减轻主动脉瘤对周围组织、器官的压迫,并消除由于主动脉瘤破裂造成大出血的危险。 After release of the aortic stent graft to the original expanded diameter ro, and the force of the stent itself Tan, attached on aortic wall covering live aorta lesion, producing a new film in the passage of blood vessel lesions , blocking its access to fresh blood supply, so that gradually thrombosis aortic aneurysm, aortic aneurysm thereby reducing the surrounding tissues, organs compression, and eliminate the risk of causing bleeding due to the rupture of aortic aneurysm.

[0005] 腔内隔绝手术经远离病变部位的血管进行操作避免了病变区域的解剖带来的副损伤;并且操作过程中对血流的阻断时间极短,避免了脏器缺血并发症;此外,多数中心型血管的腔内治疗能在局部麻酔小切ロ条件下进行,降低了麻酔要求,极大的減少了手术创伤,加速了术后恢复过程。 [0005] endoluminal vascular surgery was isolated away from a lesion operation avoids anatomical lesion area caused by the side injury; during operation and blocking of blood flow in very short time, avoiding the complications of organ ischemia; in addition, most of the center endovascular treatment vessel can be performed under local anesthesia ro small cutting conditions, reducing the requirements of Anesthesiology, greatly reducing the surgical trauma and accelerate postoperative recovery procedure. 这些优点使其成为目前主动脉瘤的首选治疗方法,但是目前这种主动脉瘤腔内隔绝术仍存在一定的问题,比如容易发生支架移位,这也是导致治疗失败和出现远期并发症的原因之一,其可以通过合理的选择和改进支架来解決。 These advantages make it the preferred treatment method currently aortic aneurysm, but now that aortic endovascular exclusion are still some problems, such as prone to stent migration, which is leading to treatment failure and the emergence of long-term complications one of the reasons that can be resolved by rational choice and stand improvement.

[0006] 专利文献W02004002370A1公开了ー种带有倒钩的胸主动脉覆膜支架,包括管状的覆膜材料、Z形支架和与覆膜支架远端相连接的裸支架组成,其中远端的覆膜材料上设置有显影部件,并且在管状覆膜材料近端的Z形支架和所述裸支架上设置有用于防脱固定的倒钩结构。 [0006] Patent Document W02004002370A1 discloses a thoracic aortic stent graft ー species barbed, comprising a tubular graft material, Z-shaped bracket and distal bare stent and stent-graft interconnected parts, wherein the distal end a developing material is provided on the coating member, and is provided with a barb for retaining the fixed structure on the proximal end of the tubular graft material Z-bracket and the bare stent.

[0007] 该现有技术中覆膜支架上指示覆膜位置的显影部件设置在支架远端的覆膜上,但由于覆膜和显影部件都具有一定的厚度,覆膜支架收缩后,覆膜与显影部件叠合在一起,因此收缩后的覆膜支架体积较大,所配置的输送器体积也较大,这就导致输送器不够小巧,在将输送器送入主动脉时可能会造成不易移动、释放覆膜支架困难的问题。 [0007] The prior art indicates the position of the stent-graft film developing member disposed on the distal end of the stent coating film, but the film and the developing member having a certain thickness, the stent graft shrinkage, film laminated together with the developing member, so the volume of the stent graft after shrinkage is large, the configured transport volume is large, which results in insufficient small conveyor, while the conveyor into the aorta may cause easy move, release the stent graft difficult problem.

[0008] 进ー步,上述现有技术中覆膜支架主要应用于主动脉弓处,覆膜支架通过其近端和远端的倒钩插入主动脉血管壁进行锚定,有效地防止了由于血液流动对弯曲的覆膜支架产生的横向力所造成的支架主体的近端朝向远端的移动和其远端朝向近端的移动。 [0008] Step ー into the stent-graft prior art are mainly used in the aortic arch, aortic stent-graft is inserted through the wall for anchoring the proximal and distal barbs, it is effectively prevented due to blood flow the proximal end of the stent body lateral force generated by bending of the stent graft caused by moving toward the distal end thereof towards the distal end and proximal movement. 但是随着主动脉的舒缩运动,覆膜支架与设于其上的倒钩会相对血管壁进行运动,则倒钩可能会脱离开血管壁或者不能完全插入到血管壁上,且同一个体主动脉的内径不均一,当所选择的覆膜支架倒钩的直径尺寸不适合锚定处主动脉的内径时,仅靠覆膜支架近端设置的ー组倒钩结构无法完全锚定住覆膜支架,特别是当覆膜支架应用于腹主动脉时,由于腹主动脉与肾动脉相连接,覆膜支架脱落后,其覆膜容易覆盖肾动脉阻挡腹主动脉与肾动脉之间的血液流动,从而给患者的生命带来危险。 However, with the systolic and diastolic movement of the aorta, the barbs will be provided on the stent graft and the vessel wall relative motion thereof, the barbs may be detached from the vessel wall, or can not be fully inserted into the vessel wall, and the same main subject uneven inner diameter of the artery, the stent graft when the selected diameter is not suitable barbed anchor at the inner diameter of the aorta, the set of barbs ー alone stent-graft structure can not be completely disposed proximal anchor stent-graft anchorage, particularly when applied to abdominal aortic stent-graft, since the abdominal aorta and renal artery is connected to the stent graft loss, which barrier coating film easily covers the renal artery blood flow between the abdominal aorta and the renal arteries, thereby to the patient's life at risk.
