Abstract

一种栓塞预防装置包含一个可收缩滤芯(105),其安装在一个滤芯载体,如导丝(101)上。滤芯(105)可以收缩到一个导管(118)的外端中,以展开和回收于患者血管系统中。滤芯(105)包含一个带有近侧进入端和远侧排出瑞的可收缩过滤体。近侧进入端带有进入口,它们的尺寸允许血液和栓塞物质进入过滤体。排出端带有排出口,它们允许血液通过但会将不希望的栓塞物质限制在过滤体中。在使用之后,导管(118)可以沿导丝(101)移动,以咬合滤芯的近端并封闭进入口,接着会从近端至远端在滤芯上滑动,从而逐渐将过滤体压缩在导丝(101)上以便回收。滤芯(105)可以方便地安装在一个管状套筒(105)上,套筒可以在位于导丝(101)上的相隔挡块(106,120)之间沿着导丝(101)滑动和旋转,从而在滤芯使用时能够对导丝进行一些独立操作。

栓塞预防装置
介绍
本发明涉及一种栓塞预防装置。
术语“中风”用于描述一种医学现象,其使得供应到脑部或脑部特定区域中的血液受限或阻塞到这样的程度,即不能充分地提供维持功能所需的氧合血液流动。脑部将被临时或永久损伤,而患者将失去某些功能,例如,视觉、语言或四肢的控制能力。中风有两种截然不同的类型,即出血性和栓塞性中风。本发明涉及栓塞性中风。
医学文献中认为颈动脉疾病是栓塞物质的只要产生源。通常,会有动脉粥样硬化斑块形成在颈动脉中。斑块的性质差别很大,但在大多数情况下,斑块可以裂开并流向血管远侧,从而阻塞流向脑部特定区域的血流并导致神经性损伤。这种疾病的传统治疗方法是外科颈动脉内模切除术,即切开颈动脉并将斑块从血管中物理去除。这种方法被广泛接受,因为据文献称神经性并发症比例低,有的文献称该比例为6%左右,尽管声称该比例可以有很大变化。
不是所有患者均适宜接受手术。有很多原因可能导致患者不能承受手术介入。这样的患者以及越来越多的实施手术的患者将接受一种贯穿导管方法的治疗。在这种情况下,该方法采用某些装置插入股动脉中并控制装置到达狭窄部位。一个气囊原生质导管将膨胀以张开动脉,而且有时需要在狭窄部位采用一个血管内扩张器。这些装置的作用同手术一样,可以使栓塞物质移出,而这种物质将随动脉血流动,并且如果增长到足够大,最终将阻塞血管并导致中风。
现已知道,可以在人的血管系统中永久性植入一个过滤器以收集栓塞物质。还知道,为此可以使用可换过滤器。这种可换过滤器通常包括伞式过滤器,在伞式过滤器中,一个过滤膜被支撑在一个可收缩架上,该架位于一根导丝上,后者用于带动过滤膜在一个顶靠着导丝的收缩位置与一个封闭血管的横向伸展位置之间运动。这种过滤器的例子见于US 4723549、US 5053008、US5108419和WO 98/33442中。各种展开和/或收缩装置可以用于伞式过滤器中。然而,当过滤器收缩时,所俘获的栓塞物质容易被向外挤压到过滤器的一个开口端,而栓塞物质块将从过滤器中逃脱,从而有可能导致灾难性后果。更常见的情况是,在从一个导管或类似物中移出之前,过滤伞就已经收缩了。同样,在过滤膜收缩时,将导致栓塞物质被挤出。此外,伞式过滤器通过要被固定在导丝上,而导丝在介入过程中的任何偶然动作都可能导致过滤器移位。
本发明的目的是克服这些问题。
因此,需要有一种栓塞预防装置,以克服这些问题。

详细说明
请参考各附图,它们显示了根据本发明的各种栓塞预防装置。总体上讲,这些装置中均包含一个滤芯,其在手术或介入过程中通常通过导丝和导管而被临时放置在一个所需位置上。滤芯提供了一个血液通道,并带有工具以俘获和保持手术过程中释放出来的不希望有的栓塞物质。当介入过程结束之后,容纳着栓塞物质的滤芯被取出。通过这种方式,可以防止因手术过程中不希望有的栓塞物质的释放而导致患者出现中风或其它并发症。
在装置的一个实施例中,采用了跨丝贯穿导管结构。临床医师将一个可控导丝穿过损伤的器官区域。之后,栓塞预防装置被穿在导丝上并远程放置到被治疗的部位处。通过操作或其它途径,滤芯被展开在血管中并收集在气囊膨胀和扩张器放置过程中产生或移出的栓塞。
首先请参考图1和2,在本例中滤芯由一个可压缩多孔结构聚合泡沫滤芯1构成,其嵌套模塑或接合在一个聚合物或金属管或弹簧或其它空心支撑元件2上。泡沫滤芯1被压缩到一个位于导管6远端的壳或罩3中,以便被推进到所需位置。一旦就位之后,罩3将后退或滤芯1被推进。这个动作将导致压缩滤芯1膨胀到所需尺寸并阻塞住血管4,只留下滤芯1中提供的一个或多个通道。滤芯1被这样设计,即提供出一个或多个通道,用以使血细胞和其它血液成分通过,但能够俘获尺寸大于滤芯孔尺寸的栓塞。通过滤芯的形成,可以保持血液流率,以使滤芯两侧的局部压降最小化。滤芯1具有一个近侧进入端7和一个远侧排出端8。进入端7带有一组进入口,它们的尺寸允许血液和栓塞进入滤芯。排出端8带有一组排出口,它们的尺寸允许血液通过,但会将不希望有的栓塞物质限制在滤芯1的本体中。
在本例中,滤芯1由多孔结构或聚合泡沫制成,这种泡沫具有开口腔结构且通常密度小于每立方米400公斤。优选的是,密度小于每立方米100公斤,理想的是小于每立方米50公斤。通过适宜地构造泡沫体的孔尺寸或附加去除材料,可以产生具有适宜尺寸的血液流通通道和俘获大尺寸栓塞的途径,从而获得过滤能力。在后文中将描述多种可以单独或同时实现滤芯1的尺寸和流率特性的结构。滤芯1的操作和展开可以通过滤芯1与覆盖壳3之间的相对运动而实现。
在操作过程中不希望导管相对于支撑元件2移动。可以通过多种不同方式将内部支撑元件2固定在导管6上,从而防止上述运动。在描述的实施例中,这种固定是通过一个导管6罩盖着支撑元件2和滤芯1而实现的。如图3A和3B所示,这种固定是这样实现的,即一个收缩卷绕管5通过收缩而捕获了罩盖导管6和支撑元件2。一旦滤芯1到达理想位置,则通过一个剥离环7而将收缩卷绕接头打开,以使外侧导管6随后移出,并使支撑元件2和滤芯1就位。
可以采用多种其它可操作结构以将支撑元件2和导管6连接起来。可以使用一个双瓣套环结构10(图4和5),其可以通过松开一个或多个螺钉或诸如小型卡箍11(图6和7)等可以松开的结构而被卸下,以释放开各部件之间的连接。
另一种可以用于将内部支撑元件2临时固定在外套或导管6上的方法是采用止血高压Touhy Borst Y连接器。利用这种市场有售的连接器,医生可以在插入动脉之前冲洗外套。外套或导管可以永久性连接在连接器上。内部管状支撑元件2穿过连接器的Touhy Borst段,并因此而穿过外套中心。拧紧Touhy Borst段将导致这种夹持松开,以使内部管状支撑元件2和外部外套在此彼此相对移动。
图8中显示了滤芯1的一种典型实施例,其中一个泡沫基体的过滤体中通过去除材料而产生了一组路径或通道20,它们能够使血液流过但能够限制住栓塞物质并防止栓塞物质通过滤芯。通道20可以通过各种方法加工出来,例如,采用激元、YAG(钇铝柘榴石)、CO2或其它激光类型的激光切割,冻结和加工或失蜡加工。多种尺寸形式可以满足需要。在图示结构中,进入口优选具有0.5mm或以上的尺寸,以俘获大的栓塞,而排出口则小于300微米。可以根据不同尺寸血管中的不同流体介质中所需过滤的不同尺寸的颗粒而容易地改变上述尺寸。
过滤介质可以通过任何现有技术连接在基管上,例如通过机械接合、溶解或粘接,并嵌套模塑在一个结构中,即基管被放置在模具中,之后,聚合材料被注射到模具中,从而在基管与聚合物元件之间的界面处连接起来。此外,泡沫或多孔元件可以基础或粘接在一个基管上。
应当指出,滤芯1具有一个圆形远端21,以便于插入,而近端22则为锥形的,以便于抽出。或者,如图9所示,远端21也可以是锥形的。
特别请参考图10,在介入过程结束后,可以将一个大孔导管25推进到滤芯1的近端22并将滤芯1拉入导管25中,从而将装置抽出。当起始锥体被拉入导管25而过滤体的其它部分在缩扁之前,滤芯1会压缩并封闭滤芯近端进入口。一旦滤芯1被完全抽入导管25中,即可以从患者体内去除。滤芯1中容纳着俘获的栓塞。
在图11至15中所示的本发明的另一个实施例中,一个被薄膜或多孔织物或网31覆盖着的辐条结构30可以被叠合入一个输送外套或罩中,以便随后在目标血管中展开。本结构中包含一个基轴33,其上沿径向或圆周方向连接着一组预成形丝30。丝30在近端汇聚成一个安装在基轴33上的可移动环或管32,而在远端汇聚成一个固定管34。管32可以移近和移远到一定程度,从而将组件以类似于伞的方式打开和封闭,以阻塞血管。辐条30可以由金属、聚合或合成材料制成。构架上覆盖着多孔材料31,多孔材料的孔尺寸被选择,以使介质能够通过,从而有效地形成一个滤膜。可以通过将一种材料,如聚氨脂或PET注塑在预成形丝上,从而将覆盖织物31连接在构架30上。之后,薄膜被lazed或通过其它方法,如机械或加热冲孔或化学蚀刻而制成多孔结构。此外,也可以在聚合物基质中加入可溶颗粒,之后再去除这些颗粒以使聚合物多孔。通过调节颗粒在聚合物基质中的比率和分布,可以控制孔隙度。
当组件被构造为轴向形状后,一个外套或罩可以在组件上滑动以覆盖组件。与前面实施例中相同,加载后的导管是通过穿在导丝上而被放置在所需位置上的。一旦到达了所需位置,外套可以向后移动,以使组件暴露在血管中。之后,一个套筒35可以向前移动以张开或展开组件。通过构造相对尺寸和选择材料可以使得套筒35不会在内管上滑动,除非施加外力以使之移动。在展开后,装置将保持张开并捕捉流向脑部的栓塞。在过程结束后,一个沿内管进给的预成形部件将与可移动管32对接,以使后者移向装置的近端,从而导致结构被封闭。之后,一个较大外套可以单独地进给到滤芯位置,而滤芯可以被拉入或被操纵着向近侧进入外套。在被抽入外套或管中后,装置可以沿着导丝或与导丝一起被取出。
请参考图16和17,图中显示了另一种栓塞预防装置。在本例中,滤芯的基本结构是一个连接在基管上的成形薄膜部件。在实际应用中,有很多种形状可以采用。当约束力去除之后,一个处于预成形形状的元件将张开成为一个构架40,其连接在一个基管41上。构架元件40可以由各种金属或聚合材料制成,例如,诸如镍钛诺等形状记忆合金或形状记忆聚合物或具有类似性能的成形不锈钢或金属,从而可以从变形状态充分恢复原形,以导致薄膜部件张开。否则的话,也可以通过机械运动或操作以使装置张开。成形薄膜部件连接在构架40周围。薄膜部件可以通过多种现有的工业技术成形。这些技术包括吹塑、浸渍模塑、溶解模塑、旋转模塑、薄膜接头以及粘接剂粘接。薄膜部件的目标是制造出一个成形形状并能够在血管中张开到一定尺寸和形状以阻塞血管。通过在元件的远端和近端产生一个点阵或组的孔,可以获得过滤能力,以使栓塞和血液能够进入装置,但远端较小的孔则允许血液通过而到达远侧血管,同时又限制住了栓塞。
在被输送到所需位置时,滤芯被一个外套覆盖或限制着。通过抽回外套或进给滤芯,可以使滤芯露出并张开以阻塞血管。在随后的过程中,滤芯能够俘获试图流向远侧的栓塞。在过程结束后,一个外套前进到装置的近端,而滤芯则带着俘获的栓塞而被向近侧拉入外套中。在这种结构中,栓塞可以容易地取出,以便随后分析。
前面所描述的本发明涉及的是一种套在导丝上使用的装置。幸运的是,本发明可以以这样的方式构造,即其自身可以被用作基本横贯装置。所有上述滤芯结构均可以安装在导丝或下面所述的横贯装置上。对于基本横贯装置,滤芯可以连接在一个实心基体上。由于不需要在另一个工具上移动,因此滤芯的缠绕内径可以较小,从而带轮某些益处。图18中显示了有关差异。滤芯1安装在一个基轴33上。一个可收缩滤芯支撑元件50在滤芯1的近端安装在基轴33上。支撑元件50带有多个可折叠臂51,它们在收缩时顶靠着轴33,并在释放后展开时向外伸展以使滤芯1在血管中扩张。
请参考图20至22,图中显示了滤芯的一种替换性结构,所示的一个处于扩张位置的可压缩滤芯1带有一个大的进入口60和若干小的排出口61。一个可收缩丝支承62装于滤芯1的近端。丝支承62可以带着滤芯1收缩在一个壳或罩中,并在释放后展开以将滤芯1支撑在血管4中。
图23至27中显示了一种替换性滤芯结构,在本例中,滤芯包含一个镍钛诺网,其可以从图23所示的收缩位置展开到图27所示的扩张位置,从而提供出一个带近端入口66和远端出口67的过滤体65。
对于基本横贯装置,装置的远端应是柔性和无损伤的。这可以通过多种途径实现,例如,制作一个弹性或聚合物元件,其具有足够的柔性从而能够在接触到血管内壁时偏转。末端部分被安装在滤芯的远端。装置的一个中央部分套着滤芯1,滤芯在展开之前一直被覆盖着。一个外套可以具有装置的全长,或者也可以利用一个致动器连接着只套着滤芯的短外套。装置的近侧部分带有气囊膨胀和扩张装置的工作台。图示中的获得工作台的方法是去除近端盖子以暴露出一个丝或弹性组件。或者,整个近端部分可以用作一个工作台。基本上讲,在用作气囊导管和扩张器时,装置应这样构造尺寸,即它的外径尺寸能够使得导管在其上自由移动。冠状制品的普通工业标准允许装置在0.014”或0.018”的直径上自由移动,而外围原生质制品采用0.035”外径。
请参考图28,连接着滤芯的基管33可以在两个挡块63与64之间移动,所示挡块安装在基本横贯导丝2上。挡块可以由各种金属或聚合材料制成,以使基管33能够在它们之间移动。在实际医用导丝中,挡块还可以采用台阶的形式。在这种应用例子中,挡块63与64之间的距离可以有很大变化。挡块的尺寸可以防止基管相对于它们移动,从而用作基管的近侧位置和远侧位置挡块。挡块可以通过多种现有工业技术安装在基本横贯导丝上;这些技术包括低温焊接、焊接、braising、碾压和粘接剂粘接。近端挡块的尺寸应足够小,以便能够装配在输送导管的内轴中。滤芯可以相对于导丝独立地轴向移动和旋转。这样可以获得良好的导丝运动和滤芯位置控制。在更换导管时,滤芯位置保持不变。可以采用任何现在有售的导丝以实施本技术。
图29中涉及一个“橄榄形”部件65;该橄榄形部件可以由各种金属或聚合材料制成,例如聚合泡沫、塑料、不锈钢或金属。橄榄形部件可以在导丝2与加载了滤芯的罩3之间形成光滑过渡,并使得滤芯容易在罩中定位。橄榄形部件可以直接连接在导丝上,或者也可以连接在一个基管33上。橄榄形部件可以通过各种现有技术,如粘接剂粘接和低温焊接而连接到导丝或基管上。橄榄形部件可以根据需要在一定范围的距离内移动到滤芯远端。橄榄形部件可以具有多种形状和尺寸。
图30中涉及处于最远侧位置时的滤芯1。滤芯在加载过程中或展开之后可以到达这个位置。挡块元件64可以防止滤芯1向远侧移动超出它。
图31中显示了处于最近侧位置时的滤芯,滤芯在装置展开过程中或展开之后可以到达这个位置。挡块元件63可以防止滤芯1向近侧移动超出它。
图32中涉及一种浮动远端,在本例中,一个挡块部件66邻近于滤芯的远端。滤芯的最远端固定在一个标记圈70或其它适宜的基体上。标记圈70不固定在基管33上。这使得滤芯远端能够沿轴向自由移动超出挡块部件。挡块部件可以采用任何适宜的形状或形式,以防止滤芯的远端向近侧移动超出挡块部件的固定点。挡块部件可以由金属或聚合材料制成,其可以通过各种现有技术,包括粘接剂粘接和低温焊接,而连接在基管33上。挡块部件66可以工作在50与70之间的任何位置上。由于滤芯可以沿轴向伸展并缠绕在较大长度上,因此滤芯的浮动远端有助于将滤芯加载到加载罩。这将使所需的加载力降低,同时又减小了加载滤芯的轮廓。浮动远端结构方便了大范围滤芯结构的加载。
图33中涉及一种带浮动远端的手风琴形滤芯。这种滤芯形状提高了滤芯的周边整体性,从而可以防止滤芯沿长度方向出现褶皱。图33a中滤芯处于展开就位状态。图33b中显示了滤芯被加载到一个加载罩中后其远端沿轴向伸展的情况。浮动远端结构适合于加载多种形状的滤芯结构。对于所示滤芯结构,在加载时需要采用一个长套以容纳滤芯增加了的轴向长度。
图34中涉及添加了弹簧元件67的浮动远端。弹簧安置在滤芯的远侧。如前面图33中所示,在加载后浮动远端沿轴向伸展,弹簧在滤芯展开时用作一个安全装置,以确保浮动远端能够返回初始位置。弹簧元件足够软,以使远端能够在加载时沿远侧方向自由伸展,但又足够硬,从而能够在展开后将远端推回初始位置。弹簧元件可以由聚合物或金属材料制成。弹簧元件可以安装在一个基体33上,而且一个挡块元件用于防止弹簧向远侧轴向移动。也可以采用其它方法,例如粘接、焊接、碾压、低温焊接,以保持弹簧元件的远端静止,或者也可以将弹簧远端碾压在基体33上。这种技术也可以通过将弹簧制成实际导丝的一部分而实现。还有其它装有回复弹簧元件的结构,如图35和36中所示。
在图35中,弹簧元件67在其近端连接在基体33上,而滤芯的远端连接着弹簧轴。这种结构使得滤芯的远端能够向远侧伸展。伸展长度可以由一个挡块68的定位或弹簧刚度确定。当外力从滤芯上撤除之后,弹簧将推动滤芯返回初始位置。在图36中,一种形状记忆合金,例如镍钛诺,用于使滤芯返回初始位置。镍钛诺支撑构架69以其远端70固定在基体33上,且其近端71是浮动的。镍钛诺的形状记忆性能将确保滤芯返回初始位置。这种结构便于使用其它市场有售或已知的形状记忆合金。这种结构也可以通过弹簧部件实现。
在图37中也采用了浮动远端结构。如前面在图27中所示的过滤体65安装在一个基体33上。扩张器的近端固定在基体上而浮动远端结构使得过滤体65能够向远侧伸展。当远侧伸展时,其外径会减小而总体长度增大。可以带有也可以不带一个挡块68,因为过滤体65最多伸展到其自身的弹性极限,该极限是由过滤体的尺寸和几何形状确定的。在外力撤除之后,过滤体的形状记忆功将导致过滤体返回初始位置。过滤体65的近端可以通过现有技术,如粘接、低温焊接或碾压而固定在基体上。
图38中显示了可以用在栓塞预防装置中的多种滤芯结构。在滤芯过大时,这些滤芯结构可以减小褶皱的轴向长度,从而用作褶皱破坏器。图示滤芯的每个端部均可以用作滤芯的远端和近端。过滤体可以是筒形的或截头圆锥形的。
请参考图40至42,图中显示了一个根据本发明的栓塞预防装置,其总体上以参考代号100表示。装置100中包含一个导丝101,其具有一个近端102和一个远端103。一个管状套筒104以可滑动的方式安装在导丝101上。一个可收缩滤芯105安装在套筒104上,该滤芯105可以在一个顶靠着套筒104的收缩储存位置与图中所示的从套筒104向外伸展以阻塞血管的扩张位置之间移动。
套筒104可以在导丝101上在一对相隔的端部挡块之间滑动,这一对挡块包括一个内挡块106和一个外挡块,在本例中外挡块由位于导101远端103处的弹簧末端107构成。
滤芯105中包含一个网110,其安装在一个可收缩支撑构架111上。网110的每端均收集在套筒104中,网110刚性连接着套筒104的一个近端112,而且网110还连接在一个可以沿着套筒104的远端114滑动的套环115上。这样,网110的远端可以沿着套筒104轴向滑动。支撑构架111也固定在套筒104的近端112上。支撑构架111的一个远端116不固定在套筒104上,因而可以以沿着套筒104轴向滑动,以便于使支撑构架111收缩顶靠在套筒104上。支撑构架111可以如图所示自然展开,也可以向内收缩顶靠在套筒104上,以装载到一个导管118或类似物中。
滤芯105带有大的近侧进入口117和小的远侧排出口119。近侧进入口117使得血液和栓塞物质能够进入过滤体中,而远侧排出口119允许血液通过但能够将不希望有的栓塞物质限制在过滤体中。
一个橄榄形导向件120安装在套筒104的远端处并具有一个圆筒形中央部分121和锥形端部122和123。远端122可以具有一个箭头形状,以使导管与橄榄形表面光滑过渡。支撑构架111被这样成形,即在滤网110上带有一个圆周槽125。如果滤芯相对于血管来说过大,则网可能出现褶皱,而该槽125可以确保不会有任何褶皱沿滤芯扩展。
在滤网110的近端带有扩大开口,以使血液和栓塞能够进入网110内部。
在使用时,滤芯105在收缩状态下安装在导管118的远端中并被输送到一个展开位置。当滤芯被蒸汽就位后,导管118后退,以使支撑构架111展开,从而使网110横贯安置着滤芯的血管。血液和栓塞可以进入滤网110的近端扩大开口。血液可以通过网壁,而网的开口或孔的尺寸使之可以限制住栓塞。在使用之后,导管沿导管101传输并首先滑过与近侧进入端112咬合着的滤芯105以封闭各开口,之后,随着导管118在滤芯105上前进,又逐渐使网收缩顶靠在套筒104上。一旦滤芯105被完全装载到导管118中,即可以被抽出。
应当指出,滤芯的一个近端是固定的,而滤芯的一个远端可以沿套筒轴向移动,从而便于收缩滤网。
此外,导管首先咬合滤网的近端,从而可以封闭滤网进入口,以防止滤网在收缩过程中栓塞物质从滤网中逃逸。
方便的是,构成滤芯的接收壳或罩的导管的末端可以由弹性材料制成,其可以径向扩展以容纳俘获了栓塞物质的滤芯。通过适宜地选择材料,同一个导管或罩可以用于展开或收缩滤芯。在展开时,弹性材料在一个缩紧位置上保持着滤芯,以使导管末端或罩的尺寸最小化。之后,在收缩滤芯时,导管末端或罩充分地弹性变形,以容纳因栓塞物质造成的滤芯的额外体积。
此外,滤芯并不紧固在导丝上,因此,例如,在更换医疗装置或替换导管时,导丝的偶然动作不会导致滤芯的意外移动。
还应当指出,根据本发明的滤芯不象很多伞式过滤器那样带有锋利的外棱边。相反,滤芯的普通管状形状更容易被血管内壁接纳。
方便的是,当滤芯在血管中展开时,导管可以取出,从而留下一个与滤芯邻近的裸露导丝,从而可以与诸如导管等现有装置和位于滤芯上游的扩张装置一起使用。
