技术领域 FIELD

本发明涉及一种入体组织的替代品的输放装置,尤其涉及一种人工心脏支架 The present invention relates to a tissue substitute into the input place, and particularly to an artificial heart stent

瓣膜的输放装置。 A discharge valve apparatus input.

背景技术 Background technique

心脏是人体最重要的器官,心脏分为左右两部分,每一部分又包括心房和心室。 The heart is the body's most important organs, the heart is divided into left and right sections, each section also includes atrial and ventricular. 左右心房和左右心室分别由房间隔和室间隔分开。 Left and right atria and the left and right ventricles are separated by the interventricular septum and the atrial septum. 在心脏内存在四个心脏瓣膜,即三尖瓣、肺动脉瓣、二尖瓣和主动脉瓣。 In the heart of memory in four heart valves, namely the tricuspid, pulmonary, mitral and aortic valve. 在人体血液循环机构中,四个心脏瓣膜起着至关重要的作用。 In the human blood circulation bodies, the four heart valves plays a vital role. 体循环机构的缺氧血液经腔静脉进入右心房,然后通过三尖瓣进入右心室,右心室收縮将血液通过肺动脉瓣压入肺循环机构,经过肺氧饱和后的血液经肺静脉回到左心房,再经二尖瓣到达左心室,左心室收缩将血液通过主动脉瓣排入主动脉而重返体循环机构。 Deoxygenated blood circulation through the vena cava into the right atrium of the mechanism, and then through the tricuspid valve into the right ventricle, the right ventricular systolic pressure of blood through the pulmonary valve into the lungs circulating means, through the pulmonary vein blood oxygenation saturation back to the left atrium, and then to reach the left ventricle through the mitral valve, left ventricular systolic blood through the aortic valve into the aorta and to return to the circulation mechanism. 主动脉瓣膜下有左右冠状动脉开口。 Left and right coronary artery at the aortic valve. 四个心脏瓣膜的结构保证了血液顺方向时瓣膜开放,逆方向时关闭,防止了血液返流而引起的心脏负担加重。 Four heart valves to ensure that the structure of the valve open, closed when the reverse direction along the direction of the blood, preventing the burden on the heart caused by blood reflux worse. 但是,由于各种原因,可以导致心脏瓣膜的后天性损伤或病变,如风湿,动脉粥样硬化等。 However, for various reasons, it may result in acquired heart valve damage or disease, such as rheumatism, atherosclerosis and the like. 此外,先天性心脏病如法乐氏四联症, 术后远期也可产生肺动脉瓣膜病变。 Further, congenital heart disease such as Tetralogy of Fallot, can produce long-term postoperative pulmonary valve disease. 瓣膜病变后表现为瓣膜功能逐渐丧失,如瓣膜关闭不全导致血液返流,瓣膜狭窄导致血液流通不畅,或关闭不全和狭窄二者兼并,以至加重心脏负担,导致心脏功能衰竭。 After the valve valvular lesions showed progressive loss of function, such as valvular regurgitation cause blood reflux, resulting in poor blood circulation valve stenosis, regurgitation or both narrow and mergers, as well as increase the burden on the heart, leading to heart failure. 对于心脏瓣膜的后天性损伤或病变, 传统的治疗方法是开胸,心脏停跳后,在低温体外循环支持下,打开心脏进行病变瓣膜的外科修复或用人工心脏瓣膜置换。 For acquired heart valve damage or disease, traditional treatment is thoracic, cardiac arrest, cardiopulmonary bypass support at low temperatures, open surgical repair diseased heart valves or artificial heart valve replacement. 现有的人工心脏瓣膜分两大类:金属机械瓣膜和生物瓣膜。 Existing prosthetic heart valve divided into two categories: mechanical valves and biological valves metal. 生物瓣膜由牛心包、牛颈静脉瓣、猪主动脉瓣等动物材料处理后制成。 Biological valve made of bovine pericardium, bovine jugular vein valve, porcine aortic valve treated like animal material. 上述开心手术的方法,手术时间长,费用高,创伤大,风险大,金属机械瓣膜置换后病人需要长期抗凝治疗,生物瓣膜的材料寿命有限,通常需要再手术。 The above-mentioned method heart surgery, surgery for a long time, high cost, large trauma, high risk patients need long-term anticoagulant therapy after mechanical heart valve replacement metal, limited biological valve material life, usually require reoperation.

为了解决上述开心手术治疗心脏瓣膜存在的问题,现在已有人尝试不作 In order to solve the above-mentioned open-heart surgery to treat heart valve problems, it has now been tried without

8开心手术,而采用经皮介入方法输放人工心脏瓣膜。 8 open-heart surgery, and percutaneous interventional lose to put an artificial heart valve. 现有技术的介入式人工心脏瓣膜有二种- The prior art invasive artificial heart valves have two kinds -

1、 球囊扩张型 1, balloon-expandable

这种球囊扩张型人工心脏瓣膜为生物瓣膜,其介入方法是在一个可塑性变形的支架上分别固定生物瓣膜,通过径向压縮在一个球囊上后直径变小, 经皮输放,然后给球囊加压使支架扩张固定,达到工作状态。 This balloon-expandable prosthetic heart valve is a biological valve, which is involved in a plastically deformable stent biological valve are fixed by radial compression in a smaller diameter after the balloon, placed percutaneously lose, then pressurizing the balloon to expand the stent is fixed, reach the working state.

1989年HenningRud ANDERSEN (专利号WO9117720)率先进行了猪主动脉瓣经导管人工心脏瓣膜置换(文献…European Heart Journal 1992 13, 704-708)。 1989 HenningRud ANDERSEN (patent number WO9117720) pioneered a porcine aortic heart valve prosthesis replacement transcatheter (Document ... European Heart Journal 1992 13, 704-708).

2000年Philippe BONHOEFFER (专利号EP1057460 )和Alain CRIBIER (专利号EP0967939 )分别首次进行了在人体的经导管介入的肺动脉瓣膜和主动脉瓣膜的人工心脏瓣膜置换。 In 2000 Philippe BONHOEFFER (patent number EP1057460) and Alain CRIBIER (patent number EP0967939), respectively, for the first time in human intervention transcatheter pulmonary valve and the aortic valve prosthetic heart valve replacement.

球囊扩张型人工瓣膜存在的缺点和问题是:其直径由球囊直径所决定, 如果人工瓣膜的直径一开始没选择好,或某些生理变化后,如自然生长、病理性血管扩张等,自然瓣膜的口径大小可能增大,而人工瓣膜的口径不能适应性增大,人工瓣膜有松动或滑脱的危险,只能进行二次球囊再扩张。 There is balloon-expandable prosthetic valve disadvantages and problems are: its diameter is determined by the diameter of the balloon, if the diameter of a prosthetic valve did not choose a good start, or some physiological changes, such as natural growth, pathologic vascular dilation, natural valve aperture size may increase, while the prosthetic valve diameter can not be increased adaptability, artificial valves are loose or dangerous slippage, and can only be re-secondary balloon dilation.

2、 自扩张型 2, self-expandable

这种人工瓣膜设有一个弹性变形支架,径向压縮后可自行扩张。 This prosthetic valve with a resilient deformable stents, self expandable after radial compression.

Marc BESSLER (专利号US5855601 )和Jacques SEGUIN (专利号 Marc BESSLER (patent number US5855601) and Jacques SEGUIN (No.

FR2826863,FR2828091)也设计了经导管人工心脏瓣膜置换。 FR2826863, FR2828091) also designed a transcatheter cardiac valve replacement. 不同的是他们用 The difference is that they use

了一个可弹性变形支架,径向压縮后可自行扩张。 A bracket elastically deformable, self expandable after radial compression.

Philippe BONHOEFFER (专利号EP1281375, US2003036791)的人工心脏瓣膜利用一个可弹性变形支架,在支架上游端或远端装有触头,压在内外两个鞘管内。 Philippe BONHOEFFER (Patent No. EP1281375, US2003036791) utilize a prosthetic heart valve stent is elastically deformable, at the upstream end or distal end of the stent with the contacts, both internal and external pressure in the sheath.

本申请人曾在中国发明专利申请号200410054347.0中提到使用了中段为鼓型的支架瓣膜和自扩型加强化合成支架瓣膜,及捆绑式输放装置。 The present applicant has invented in Chinese Patent Application No. 200410054347.0 mentioned middle is used for self-expanding stent-valve and the stent-valve reinforcing synthesis and release the bundled transmission of a drum-type apparatus.

自扩张型人工瓣膜存在的缺点和问题是:自扩张型人工心脏瓣膜与鞘管间摩擦力大,影响人工瓣膜准确释放。 The existence of a self-expandable prosthetic valve disadvantages and problems are: a self-expandable prosthetic heart valve between the sheath and high friction, impact prosthetic valve accurate release.

该捆绑式输放装置的支架拉线,穿过人工瓣膜的可变形单元时摩擦力大,不穿过时拉线易脱位。 The stent device bundled transmission cable release, high friction when the deformable section through the prosthetic valve through the cable is not easily dislocated.

上述球囊扩张型和自扩张型人工心脏瓣膜存在的共同缺点和问题是- Above balloon-expandable and self-expanding presence of artificial heart valves are common shortcomings and problems -

1、 现有的介入式人工支架瓣膜的输放装置和径向压缩下的支架瓣膜较硬,弯曲性差,经过主动脉弓不容易,不能对准自然主动脉瓣膜口。 1, a conventional transmission artificial intervention stent-valve in the discharge device and the stent-valve hard radial compression, bending is poor, not easily through the aortic arch, misalignment of the native aortic valve orifice.

2、 即便在X光透视帮助下,介入式人工支架瓣膜和它的输放装置的轴向上下游定位也因对解剖位置的判断不准和血流冲击下的人工瓣膜不稳定而变得不容易。 2, even in X-ray help, artificial intervention stent-valve and its output axial discharge means positioned downstream also because the prosthetic valve is determined under unstable and blood allowed to impact on the anatomical location and becomes easily. 介入式人工主动脉瓣膜如果位置偏上游可影响二尖瓣,如果位置偏下游可堵阻冠状动脉开口。 If invasive prosthetic aortic valve upstream of positional deviation may affect the mitral valve may be blocked if the positional deviation downstream blocking the coronary ostia.

3、 介入式主动脉瓣人工支架瓣膜和它的输放装置的旋转方向定位没能解决。 3, interventional artificial aortic stent-valve and its output rotation direction the discharge means is positioned failed to solve. 介入式人工主动脉瓣膜如果旋转位置不对可堵阻冠状动脉开口。 Invasive prosthetic aortic valve may be blocked if the rotational position of not blocking the coronary ostia.

4、 自扩型人工支架瓣膜高度压縮下,鞘管的回退会遇到很大的阻力。 4, the self-expanding stent-valve Artificial highly compressed, the rollback of the sheath encounter strong resistance. 退 Retreat

鞘管的阻力和困难还会使操作者将已定好位的人工支架瓣膜移位。 Resistance and difficulties sheath also allows the operator to have a good bit of the artificial stent-valve displacement.

5、 在释放过程中,支架瓣膜逐渐半扩张到全扩张,所需时间超过一个心 5, during the release, the stent-valve is gradually expanded to half full expansion, the time required for more than one heart

跳周期。 Skip cycle. 扩张的支架瓣膜会阻碍血流,支架瓣膜也可因血流冲击而使其位置改变。 Expanding stent-valve impede blood flow, the stent-valve may also be due to the impact of blood flow and change its position. 特别是球囊扩张型人工支架瓣膜在球囊扩张过程中完全阻断血流。 Artificial particular balloon-expandable stent balloon during expansion valve completely blocking blood flow.

6、 如果病人已有冠状动脉搭桥(Coronary Artery Bypass),已植入的人工支架瓣膜不应该在升主动脉处影响搭桥开口的血液灌流。 6, if the patient has CABG (Coronary Artery Bypass), the stent implanted artificial aortic valve should not affect the blood perfusion of the bypass opening.

7、 Jacques SEGUIN和Philippe BONHOEFFER的主动脉瓣自扩型支架瓣膜如能成功植入,虽然术后不会马上影响冠状动脉的灌流,但是支架中部在主动脉根部不贴血管壁,让血流从支架网眼中流过, 一方面会有血栓形成的可能;另一方面会影响或妨碍未来可能的冠状动脉介入诊断和治疗。 7, Jacques SEGUIN and Philippe BONHOEFFER aortic valve, such as self-expanding stent successfully implanted, although surgery will not immediately affect the perfusion of the coronary arteries, but the center stand is not attached to the vessel wall in the aortic root, let the blood flow from flowing through the stent mesh, may be an aspect of thrombosis; on the other hand that affect or interfere with possible future diagnosis and treatment of coronary intervention.

8、 释放扩张后的支架瓣膜的固定也存在以下问题: 8, released after expansion of the stent-valve also fixed the following problems:

a) 收縮期和舒张期血流冲击会使固定不好的人工支架瓣膜移动。 a) systolic and diastolic flow impact will fix a bad move artificial valve stent.

b) 有些主动脉瓣关闭不全的病人其主动脉根部术前已有病理性扩张,需要很大的支架瓣膜才能与其吻合固定。 b) Some patients with aortic insufficiency of its roots before surgery pathologic aortic dilatation, requires a lot of stent-valve to match its fixed.

c) 有些病人在人工支架瓣膜植入后局部会有解剖性变化,如扩张,使不能相应变化的支架瓣膜失去有效固定。 c) there will be partial in some patients after stent-valve implantation of artificial anatomical changes such as expansion, the stent-valve is not fixed to a corresponding change in the effective loss.

9、 扩张固定后的人工支架瓣膜在很多情况下有瓣周漏(Para valvular leaks),即血液从支架瓣膜和血管壁之间漏过。 9, the expandable stent-valve artificial fixed paravalvular leak (Para valvular leaks) In many cases, i.e., from the blood pass undetected between the vessel wall and the stent-valve.

1011、如果为了固定好而采用大直径支架瓣膜,瓣叶联合点(Commissure) 会承受很大应力,造成瓣膜叶联合点撕损。 1011, if in order to secure the stent and the use of large diameter valve, the leaflets joint point (Commissure) will be under a lot of stress, causing the valve leaflets joint tear point loss.
