本申请要求于2013年3月15日提交的美国临时申请No.61/789,423的优先权权益,并且将该文件的全部内容通过引用结合于此处。
技术领域
本发明涉及一种可植入装置。更特别地,本发明涉及可通过静脉植入的闭塞装置,且在一些实施例中用于动脉瘤治疗。
背景技术
血管系统的壁(尤其是动脉壁)可形成所谓动脉瘤的病理性增大区域。众所周知,动脉瘤具有易于破裂的薄弱的壁。动脉瘤可能是由疾病、损伤或者先天异常所引起的血管壁变弱的结果。动脉瘤可能在身体的不同部位发现,最常见的是腹主动脉瘤和神经血管中的大脑或者脑动脉瘤。当变弱的动脉瘤壁破裂时,尤其如果是脑动脉瘤壁破裂时,可能会导致死亡。
动脉瘤通常通过将血管变弱部分从动脉循环排除来治疗。为了治疗脑动脉瘤,这样的加强按照包括以下方式的多种方式来完成:(i)外科夹紧术,其中金属夹围绕动脉瘤的底部固定;(ii)采用小的柔性线圈(微线圈)填塞动脉瘤;(iii)采用栓塞材料“填充”或“填塞”动脉瘤;(iv)利用可分离的气球或者线圈闭塞向动脉瘤供应的载瘤血管;以及(v)血管内支架植入术。
在将压缩支架引入至血管中并将其定位在狭窄部或者动脉瘤的区域中的常规方法中,具有远侧末端的引导导管经由皮肤引入至病人的血管系统中。引导导管在血管中前进直到它的远侧末端接近该狭窄部或动脉瘤。设置在第二内导管内腔中的导丝和该内导管通过引导导管的远侧末端前进。导丝接着前进至引导导管的远侧末端之外而进入到血管中,直到携带压缩支架的导丝的远侧部分设置在血管中的病变处。一旦该压缩支架位于病变处,支架就可释放并膨胀,以使它支撑血管。
许多公司已采用球型栓塞装置用于动脉瘤的治疗。通常,用于治疗动脉瘤的编织球栓塞装置和/或其它类型的栓塞通过中断血液流动并随之形成血栓而操作。
该装置的编织密度影响了通过该装置的血液流动。在植入物中更大的编织密度导致更大的流动中断、更少的闭塞时间和/或耐久闭塞的提高可能性。装置按轨迹前进实现血管内进入所经过的微导管的尺寸对于可包括在该装置中的编织物量(即,丝的尺寸和数量)设置了主要限制。用于按轨迹前进的装置构造因而变成了剩余设计变量,可改变该剩余设计变量以获得期望的性能。
发明内容
用于治疗动脉瘤的系统和过程可包括具有一个或更多个可膨胀元件的栓塞装置,该可膨胀元件可插入至动脉瘤中以促进血栓形成的治疗效果。该元件可具有不同的具体特征,上述特征包括孔隙率、组成、材料、形状、尺寸、涂层等。这些特征可为了获得该装置期望的治疗或放置而选定。
根据一些实施例,该装置可包括由单一连续材料件所形成的至少两个部分,该材料件定形成使上述部分包括不同的形状或尺寸。在一些实施例中,第一部分可提供第一功能,第二部分可提供第二功能。第一功能可包括降低该装置的元件或部分的移动以确保该装置不会刺穿为该装置提供框架的动脉瘤壁、或者用于该装置操作的其它支撑或结构的功能。第二功能可需要采用单个或者多个互连元件填充动脉瘤体积。当放置时,第一功能可在第二功能之前或者之后实现。因此,第一部分可在第二部分之前、之后或者与第二部分同时放置在动脉瘤中。
例如,第一部分可用作在第二部分之前可放置于动脉瘤中的无创伤末端部分,当容置于动脉瘤中时该第一部分为第二部分提供“巢”或垫子。进一步,第一部分可包括内部可插入有第二部分的框架构件。因此,在一些实施例中,第一部分和第二部分可具有相关的或随附的功能。因此,该装置的一些实施例可有利地将多个元件集成至提供了动态和复杂功能性的包括单一连续材料件的装置中。
例如,根据以下描述的各个方面,示出了主题技术。为了方便,该主题技术的多个方面的各种示例以编号的条款(1、2、3等)来描述。这些作为示例而提供并且不限制主题技术。需要注意的是,任何从属条款能够以任何结合方式结合并置于各自的独立条款中(例如条款1或条款5)。其它条款可以以类似的方式存在。

具体实施方式
在以下详细描述中,阐述许多具体细节以对主题技术提供全面理解。应当理解的是,主题技术在没有一些这些具体细节的情况下也可实施。在其它情况下,众所周知的结构和技术未详细示出,从而不会模糊主题技术。
进一步,虽然本说明书阐述了各种实施例的具体细节,但是可以理解的是说明书仅为说明性的,绝不应当解释为限制。另外,可以预料的是,尽管在动脉瘤治疗的背景下公开或示出了特别的实施例,但是这些实施例还可在用于闭塞血管的其它应用中使用。此外,这些实施例和本领域技术人员对其所作改进的各种应用也包含于此处所描述的一般构思。
在此处提供了传送系统、植入物以及制造植入物的方法。该植入物可用于治疗神经血管缺陷。一种是在颅内动脉瘤栓塞/闭塞中所使用,另一种是在载瘤血管闭塞(PVO)或牺牲中所使用。进一步,一些实施例可包括与本受让人的美国专利No.8,142,456的某些方面相关的特征,该专利的全部内容通过引用而结合于此。
根据此处所公开的一些实施例,栓塞植入物或者装置可包括具有不同形状或构造的两个或者更多个部分,这些部分可使得该装置能够提供不同的功能或操作特性。该装置能够包括沿着它的每个部分延伸的单一连续材料件。该材料件可被定形为使得这些部分的每一个获得期望的形状或构造。因此,由于该装置的一些实施例仅使用单一材料件,所以该装置可有利地将在之前通过若干装置所实现的各种功能集成至一连续装置中。因此,一些实施例允许该装置在作为单一或者单个元件操作的同时实现各种不同功能。
例如,该植入物的一些实施例可由在未压缩/未约束状态中限定了开放体积(在横截面中构造成椭圆状、类球状、球状、大体上球/圆状、心形、卵形、桶形或者其它形状等)的管状编织物原料形成,该管状编织物原料包括例如镍钛诺的弹性材料。该装置可设置在动脉瘤囊(例如血管分叉点处)中。该植入物可经过通过主血管(例如基底动脉)的入口(优选地采用例如此处所描述的传送系统穿过商业上可用的未示出的微导管)传送。
该装置可包括至少两个部分:包括无创伤末端、颈部阻塞或框架部分的第一部分以及包括体积填充部分的第二部分。在一些实施例中,第一部分在设置在要被闭塞的身体内腔(例如动脉瘤)中时可设置为先于第二部分。在这些实施例中,该装置的第一部分或者元件可定形为提供与无创伤进入至动脉瘤或者动脉瘤的框架有关的功能。进一步,该装置的第二部分、末端部分或元件可定形为膨胀至一个或者更多个可膨胀元件中,可膨胀元件可前进至动脉瘤中以填充或者填塞动脉瘤空间或者阻塞动脉瘤的颈部或开口以防止栓塞材料由此形成疝。然后,放置顺序还可颠倒,例如在第一部分包括颈部阻塞部分的时候。
在一些实施例中,该装置的第一部分可定形为最小化横截面尺寸、轮廓或直径。例如,该装置的第一部分可拉下(例如扭转或者纵向拉直)至最小横截面尺寸,且定形为使得当未约束时,第一部分呈现最小横截面尺寸。进一步,在一些实施例中,第一部分可定形为提供第二构造(例如螺旋状构件或框架构件)。在一些实施例中,第一部分可定形为包括柔性线圈型部件或者一系列互连的可膨胀元件。因此,第一部分可例如提供无创伤保护、框架或者体积填充的功能。
在一些实施例中,该装置的第二部分可定形为从在无约束时的最小横截面尺寸膨胀至比第一部分的无约束轮廓大得多的膨胀轮廓。例如,第二部分可膨胀成圆形三维形状(例如椭圆体、杯体、桶体以及它们的组合)。因此,第二部分可提供例如体积填充或者颈部阻塞的功能。
进一步,该装置的第二部分可定形为多个可膨胀的互连元件。例如,第二部分可膨胀为一系列互连的椭圆体。正如此处所讨论的,还可应用各种其它形状和特征。
在一些实施例中,该装置可具有预定构造,无论该装置是仅具有单个可膨胀元件还是具有多个可膨胀元件。该预定构造可基于典型的动脉瘤形状,从而允许选择具体装置。然而,装置的个体元件还可基于期望的性质而设置。
在一些实施例中,该装置的第一部分或者第二部分的一个或多个可膨胀元件可定形或者制造成各种几何形状或者部分几何形状。
例如,为了容置各种动脉瘤构造,一个或多个可膨胀元件的形状或尺寸可选自各种球形或者非球形,包括圆柱、半球、面条状、多面体(例如立方体(型)、四面体(例如锥体)、八面体、棱柱体)、线圈、长球体、扁球体、板(例如盘、多边形板)、碗(例如诸如空心半球形容器的开口容器,或者其它开口中空容器,无论是半球形、圆形还是其它形状)、非球形回转表面(例如环、圆锥、圆柱或者绕着中心点或者共面轴线转动的其它形状)以及它们的组合。
各种传送系统和工序可被实施以传送具有具体尺寸或形状且在一些实施例中具有多个可膨胀元件的装置。进一步,提供的系统和方法用于将装置传送至动脉瘤和/或重获该装置以用于移出或者再定位。在此进一步讨论这些系统和工序的示例。
另外,尽管在一些实施例中,单个装置可用于单独填充动脉瘤且提供期望的填塞密度或者填充体积,但是多个装置也可用于填充动脉瘤且提供期望的填塞密度或填充体积。
可选择地,液体栓塞和/或框架元件可用于与一个或者更多个装置结合,以有助于传送、与动脉瘤接合或者提高填塞密度或填充体积。这些实施例的任何一个允许增大填塞密度或填充体积以避免动脉瘤重通。
现在参考附图,图1示出了设置在血管14中的动脉瘤12内部的栓塞装置10的实施例。该装置10可尤其适于在患者的弯曲神经血管中使用,用于至少部分地在脑动脉瘤中部署。
脑动脉瘤可自身以草莓状存在(即所谓的草莓状或者囊状动脉瘤),该动脉瘤在神经血管中凸出。草莓状动脉瘤可位于分叉点或者其它分支血管处。还可利用此处所公开的装置的实施例来治疗包括纺锭状动脉瘤的其它类型的动脉瘤。
该装置10包括至少一个可膨胀元件。在一些实施例中,装置10可包括多个可膨胀元件。进一步,该装置10的给定可膨胀元件与该装置10的另外的可膨胀元件相比可具有一个或者更多个不同的特征。可膨胀元件可由可高度压缩的材料形成,并随后当释放至动脉瘤中时膨胀且与流体(例如在动脉瘤内部的流体)接触。
现在参考图2至3C,一些实施例可提供具有两个或更多个可膨胀元件的装置100。例如,该装置100可包括从第一或者收缩的横截面尺寸或轮廓膨胀至膨胀的横截面尺寸或轮廓的第一部分102和第二部分104。正如此处所讨论的,该第一部分102的膨胀轮廓可在形状或尺寸上不同于第二部分104的膨胀轮廓。如图3C中所示,第一部分102可包括大体上球形形状,同时第二部分104可包括在螺旋路径上延伸的带束构造。
该装置100可由连续材料件形成。例如,该材料可包括多根编织丝线、针织材料或者梭织材料。进一步,在一些实施例中,该装置100可包括定形为限定第一和第二部分102、104的管状网状物。例如,对于第一部分102,管状网状物可定形为使第一部分102限定了打开体积并且丝线朝向第一部分的近侧和远侧末端112、114汇集,以形成大体上的椭圆体形状。
根据一些实施例,第一部分102可包括例如椭圆体、类球体、球体、大体上球状/圆状、心形、卵形、筒状等的各种三维形状的任何一个。特别是,在一些实施例中,第一部分102可包括选自如下组的形状,该组包括:圆柱、半球、多面体、长球体、扁球体、板、碗、空心结构、苜蓿状、非球形回转表面以及它们的组合。可提供具有大体上球形形状的附加可膨胀元件。
另外,第二部分104的形状可不同于第一部分102的形状。例如,第二部分104可包括螺旋形状、曲折形状、正弦形状或者各种三维形状的任一形状。
该装置和末端部分示出为由多根编织丝线形成。第二部分104(与第一部分102的尺寸相比)可具有能生成大的线圈环的较大的线圈直径。在一些实施例中,多根编织丝线可成束以形成具有至少两个环以及多达10个环的线圈。进一步,在一些实施例中,第二部分104可具有介于大约3个和大约8个之间的环。此外,在一些实施例中,第二部分104可具有大约6个环。
此外,在一些实施例中,第二部分104可沿着三维形状的边缘延伸,使得第二部分104在插入至动脉瘤中时作为框架构件操作。
可选择地,第一和第二部分102、104可具有不同的尺寸。例如,如图2所示,第一部分102的膨胀轮廓可大于第二部分104的膨胀轮廓。然而,如图11所示,图11示出了该装置的第二部分可形成在框架构件中,该装置的第二部分的膨胀轮廓可大于第一部分的膨胀轮廓。
根据一些实施例,第一和第二部分102、104的轮廓、尺寸或者形状可沿着它们的各自长度变化。例如,在一些实施例中,第一部分102可包括多个可膨胀元件(例如参见图11的部件710)。在这样的实施例中,多个元件可膨胀至不同的轮廓、尺寸或形状。同样地,第二部分104也可膨胀至可变轮廓。例如,第二部分104可定形为沿着可变螺旋状路径延伸的螺旋构件。进一步,根据一些实施例,第二部分104可包括螺旋构件和框架构件。
根据一些实施例,还提供了将栓塞装置置于动脉瘤中的方法。图3A至3C示出了装置100移动通过导管200的部署顺序。这些图示出了装置100在导管200中膨胀或重获的各种阶段。根据此处所公开的方法的一些实施例,装置100在初始部署至动脉瘤的基底中之后可在导管200中局部地释放和重获。因此为了提供在动脉瘤中的较好的放置和最佳的结果,可谨慎地选定装置100的放置。
在传送系统使得临床医生能够取回或者重获该装置的一些实施例中,传送/取回构件可包括由Covidien LP所制造的鳄鱼线取回装置。鳄鱼线取回装置可包括柔性线,该柔性线在柔性线远侧末端具有多个抓紧臂或者部件(例如四个臂)。用于抓紧部件的其它实施例包括苜蓿叶状设计、鱼钩状设计或者可分解的联接器。
进一步,适用于通过弯曲神经血管的空间进入治疗位置的导航的合适的微导管在通常所授予的美国专利No.7,507,229中公开,该文件的全部内容结合于此。
如图3A所示,装置100可朝向导管200的远侧末端202前进。在一些实施例中,可在第一部分102的近端处推压装置100。然而,通过在第二部分104的远侧末端118处施加远侧力,装置100还可经由附接至引导线或者可操作以使装置100通过导管200前进的其它构件的远侧末端而被牵引。
可选择导管200,以使内腔204的内径非常接近第二部分104的第一或者收缩的定形横截面尺寸或者轮廓210。例如,在一些实施例中,第二部分104可定形为直径为0.021英寸。当前进通过导管内腔204时,如果导管内腔204非常接近第二部分104的定形直径,则第二部分104可趋于避免屈曲。因此,在一些实施例中,内腔204的直径应当小于装置100的最小部分的横截面尺寸或直径的2倍。优选地,内腔204的直径小于装置100的最小部分的横截面尺寸或直径的2倍。进一步,内腔204的直径可小于装置100的最小部分的横截面尺寸或者直径的1.5倍。
有利地,当装置100放置于动脉瘤中时,第二部分104可为装置提供软垫或者缓冲区。起初,第二部分104可用于有助于将装置100最初放置和定位至动脉瘤中。例如,第二部分104可部分地暴露(例如,鞘管或导管可相对于该装置100向近侧缩回,使得第二部分104的至少一部分从鞘管或导管的远侧开口延伸)。第二部分104的暴露部分可接着用于“锚定”或者抓住组件,使得装置100和/或鞘管/导管可进一步插入至动脉瘤中。
在一些实施例中,装置100可包括不透射线标识。例如,不透射线标识可放置于第二部分104的远侧末端118。因此,当该装置100前进时,装置100的定位和放置可在荧光透视法下易于可视化。进一步,在一些实施例中,一根或更多根丝线、材料或者涂层可施加至第一部分102和第二部分104中的任一或者两者。
一旦装置100和导管200相对于动脉瘤合适地定位(例如在动脉瘤中或者至少邻近于动脉瘤的颈部,以使该装置100可膨胀至与动脉瘤壁接触)时,该装置100可之后膨胀至与动脉瘤壁接触。
如图3B所示,当该装置100前进至该导管200的远侧末端202的外部时,第二部分104可膨胀。根据一些实施例,即使当从导管200释放时,第二部分104的横截面尺寸也不会倾向于膨胀超过0.021英寸的定形横截面尺寸或者直径。代之的是,第二部分104可膨胀至第二构造(例如螺旋构件或者框架构件)。
当释放时,如图3C所示,装置100可从它的第一或者收缩构造膨胀,以使第一和第二部分102、104膨胀至与动脉瘤壁接触。根据一些实施例,当装置100膨胀至与动脉瘤壁接触时,第二部分104可提供一套或一定体积的材料,远侧末端(且在一些实施例中在该远侧末端处的标识或紧固件)可抵靠该材料放置。这能够尤其有利于保护动脉瘤的壁免受该装置的任何衬套或者非柔性结构(例如参见图4B的部件322)的损害。
例如,在一些实施例中,第二部分104可包括一束编织丝线,第二部分104可提供明显的衬垫或缓冲,该装置100的远侧末端可安全地安置于衬垫或缓冲中。这些和其它的实施例的特征可有利地用于将第二部分104(例如在一些实施例中是该束编织丝线)聚集为成束构造,如图1所示,该成束构造可为了防止或避免刺穿动脉瘤穹顶而插置于该装置100的远侧末端和动脉瘤穹顶之间。
图4A至4B示出了装置300、320的侧截面图。参考图4A,装置300、320均包括第一部分302和第二部分304。如图所示,装置300可包括从第一部分302延伸至第二部分304的单一连续材料件310。例如,材料310可包括管状的编织物、针织物、梭织物或者网状物。管状编织物或网状物可包括从第一部分302连续地延伸至第二部分304的内腔312。然而,如图4A至4B二者中所示,内腔312的内部轮廓或尺寸在第二部分304中可包括大体上为零的横截面尺寸。根据此处所公开的任一实施例,横截面尺寸可包括直径或宽度。
例如,即使内腔312具有开口穴部,横截面尺寸也可“大体上为零”。术语“大体上为零”可涵盖第二部分304的内腔312在非零横截面尺寸中汇集于自身(例如当内腔312在定形构造中塌缩,它的内表面接触自身)的构造。此外,术语“大体上为零”还可指的是相对于第一部分302的膨胀尺寸形成鲜明对比(即小得多)的尺寸。实际上,当从约束释放时,在第一部分302中的内腔312的横截面尺寸可膨胀至远大于在第二部分304中的内腔312的程度。
另外,根据一些实施例,第一和第二部分302、304可限定过渡部分314,在此处第一部分302的材料朝向自身汇聚,直到获得显著减小的轮廓,在此处第二部分304起始。在一些实施例中,如图4A所示,过渡部分304可形成为定形构造。然而,在一些实施例中,如图4B所示,过渡部分314可进一步包括衬套322,该衬套322可固定过渡部分并朝向减小的轮廓推动材料310。
现在参考图5,示出了栓塞装置400的另一实施例。该装置400可包括单层材料。例如,装置400可包括单层编织丝线。然而,如图7所示,栓塞装置500的至少一部分可包括多层的材料(例如编织丝线)。
用于制造图5的装置400的工艺在图6A至6C中示出。如图5所示,装置400包括大致球状的第一部分402和大致螺旋状的第二部分404。起初,如图6A所示,具有大体上恒定的内部尺寸或轮廓的单一管状编织物410放置于第一线420上。之后,该编织物410可放置于模板430上。在一些实施例中,一旦该模板430已插入至该编织物410中,压缩模板432就可围绕编织物410放置。该编织物410可接着定形为使得该编织物410在模板430上所配合的部分被定形为期望的三维构造。
其后,该编织物410的剩余部分440可纵向伸展、扭曲、纵向拉直或者沿着该编织物410的纵向轴线拉伸。编织物410的这种伸展可减小编织物410在剩余部分440中的横截面尺寸。
根据一些实施例,剩余部分440还可被物理上修改。例如,剩余部分440的一根或者更多根丝线可从剩余部分440上切除和/或去除。该剩余部分440的改变可有助于经由定形来变化轮廓,并允许该装置的第二部分取得期望的构造或轮廓。
当剩余部分440减小至期望的轮廓时,剩余部分440可绕着心轴或者线450缠绕并定形为期望的三维形状。
另外,如图7所示,该装置500可包括多层(在该实施例中示出为双层)第一部分502和单层第二部分504。第一部分502可由管状编织物形成,该管状编织物可外翻或者内翻至自身上以使该编织物连续地延伸为多个层。例如,如图7所示,管状编织物510可限定第一端部512和第二端部514。另外,管状编织物510可限定折叠端部516。
图8A至8C示出了可形成装置500的工艺的实施例。如图所示,编织物材料510可放置在线520上。编织物材料510的一部分522可(例如利用丝线扣)夹紧或者系在线520上。该部分522可接着在编织物材料510的一部分524在图8B中所示的步骤中外翻在该部分522上并定形之后变成折叠端部516。
如图8B中所示,一旦该部分524外翻,模板530就可插入至编织物材料510的第二端部514中。与以上关于图6B所记载的讨论相似,为了定形该装置500的第一部分502,压缩模板532可接着设置在编织物材料510和模板530的周围。另外,在第一部分502定形之后,第二部分504可通过绕着心轴550缠绕编织物材料510而定形,以使第二部分504定形为期望的构造。关于图6B至6C以上已经讨论的进一步细节为了简洁而将不再重复。
这样,在该装置包括椭圆体形状的实施例中,该椭圆体可被包封于另一椭圆体中以提供具有两层的椭圆体形状装置。因此,该装置的第一部分和/或第二部分可包括多层。然而,如图7至8C的实施例中所示,尽管附加层可绕整个装置或者仅绕第二部分延伸,但是一些实施例可有利地构造为使得附加层仅局部地绕着该装置的第一或者第二部分延伸。
根据一些实施例,该装置的第一部分可包括体积填充部分和/或颈部阻塞部分,该装置的第二部分可包括无创伤部分、体积填充部分和/或框架构件。例如,图1至4B示出了一种装置的实施例,该装置的第一部分包括体积填充部分,第二部分包括无创伤部分。图9A至10B示出了一种装置的实施例,其中,该装置的第一部分包括颈部阻塞结构,第二部分包括体积填充和/或无创伤部分。进一步,图11示出了该装置的实施例,其中,第一部分包括体积填充部分,该装置的第二部分包括框架构件。
图9A至9B示出了具有杯状形状的第一部分602和螺旋延伸的第二部分604的装置600。正如此处所讨论的,该装置600可由单一连续材料件形成,使得第一和第二部分602、604彼此一体连接。
图9B示出了该装置600放置于动脉瘤12中。如图所示,第一部分602可膨胀为与横跨动脉瘤12的颈部16的血管壁并置。另外,第一部分602可接合血管壁,以使第一部分602横跨动脉瘤颈部16锚定,从而防止第二部分604在动脉瘤12中形成疝。
类似地,图10A至10B示出了具有圆柱形状或者桶形状的第一部分652和螺旋延伸的第二部分654的装置650。正如在此处讨论的,该装置650可由单一连续材料件形成,以使第一和第二部分652、654彼此一体连接。
图10B示出了该装置650放置于动脉瘤12中。如图所示,第一部分652可膨胀为与横跨动脉瘤12的颈部16的血管壁并置。有利地,第一部分652可设置为接合且向外压靠在颈部16处的血管壁上,这可使得该装置650能够用于阻塞宽颈动脉瘤。第一部分652可接合血管壁,以使第一部分652横跨动脉瘤颈部16锚定,从而防止第二部分654在动脉瘤12中形成疝。
图11示出了包括第一部分702和第二部分704的装置700的又一实施例。第一部分702可包括多个个体可膨胀元件710。此处所公开的实施例的任何一个可沿着第一部分包括多个元件。该装置700有利地使用一系列可膨胀元件710,因为第二部分704定形为框架构件720。如图所示,框架构件720可包括多个环或者以其它方式限定具有中空内部的框架或结构,该可膨胀元件710可在部署装置700期间插入该中空内部。
图11还示出了该装置的实施例的第二部分可定形为大致扁平的构件。如图所示,框架构件720包括一系列由扁平构件所形成的圈。
根据一些实施例,一旦该装置700已放置于动脉瘤中,附加线圈或者栓塞材料就可穿过框架构件720的开口端部前进。合适的编织物材料、结构和用于制造该框架构件的方法在以下文件中公开:共同受让的、授予Mazzocchi的美国专利No.6,168,622、美国专利No.8,142,456(2012年3月27日发布)、美国专利申请公开No.2011/0319926(2010年11月11日提交)以及美国专利申请公开No.2012/0330341(2011年6月22日提交),上述文件的每一个的全部内容通过引用而结合于此。编织物材料可包括不锈钢、镍钛钴铬合金等。
与可膨胀元件710和可选择地线圈或其它材料结合起来的框架构件720可提供以下益处:提供良好的颈部覆盖,同时防止栓塞装置在载瘤动脉中形成疝。另外,这种系统的使用还可增加填塞体积效率并实现停滞。
在将框架构件720和可膨胀元件710放置于动脉瘤中时,框架构件720的开口端部或最宽间隙可设置在动脉瘤的颈部处,以有助于经由可放置于框架构件720的开口端部或间隙中的导管插入可膨胀元件710和任何附加材料。在用于该框架结构的具有梭织、针织、编织或网状材料的实施例中,编织图案可适当地对齐以有助于材料进入该框架结构中。正如在此处所公开的其它实施例中,框架结构可包括不透射线的材料或者元件,该不透射线的材料或者元件有助于可视化且使得临床医生能够根据需要在动脉瘤中对齐该框架结构。
液体栓塞的注入可增加该装置中的总填塞密度或者填充体积。
一种适合的液体栓塞是由加利福尼亚州阿尔文市(Irvine)的Covidien LP所制造的OnyxTM液体栓塞系统。OnyxTM液体栓塞系统是用于治疗脑动静脉畸形的非粘性液体。OnyxTM液体栓塞系统由溶解在DMSO(二甲亚砜)中的EVOH(乙烯醇)共聚物和悬浮的微粉化钽粉末组成,以提供用于在荧光透视法下的可视化的对比。其它液体栓塞溶液也是可以预期的。
根据一些实施例,该装置的至少一部分可包括用于增强该装置的至少一个或者每一个可膨胀元件的治疗性、易膨胀性或者成像性质或者特性的涂层或材料。
在一些实施例中,该装置的至少一部分可涂覆有生物相容性材料以提升内皮化或者提供治疗效果。
该涂层包括血栓形成涂层(例如纤维素、纤维蛋白原等)、抗血栓形成涂层(例如肝素和它的衍生物)或者t-PA、内皮增强涂层或者促进剂(例如诸如VEGF和RGD肽)、和/或它们的组合。药物洗脱涂层和药物洗脱泡沫复合物(例如消炎药或抗生素)涂层也是预期的。这些药物洗脱组份可包括营养素、抗生素、消炎药、抗血小板剂、麻醉剂(例如利多卡因)以及抗增生剂(例如诸如泰素的紫杉醇衍生物)。亲水性的、吸湿的以及疏水性的材料/剂也是预期的。
在一些实施例中,该装置的一个或者更多个部分还可包括膨胀限制涂层,该涂层将元件的膨胀从它的自然膨胀率减缓至更低的膨胀率,以使在膨胀工艺期间,如果有必要,该元件的位置可在动脉瘤中调整或者该元件可从动脉瘤去除。能用作膨胀限制涂层的聚合物的示例可包括疏水性聚合物、有机非极性聚合物、PTFE、聚乙烯、聚苯硫醚、油类以及其它类似的材料。
在一些实施例中,该装置只有特定区段可嵌入或者涂覆有为可膨胀元件提供期望特性的试剂。例如,该装置可包括非血栓形成涂层,所施加的该非血栓形成涂层小于整个第一部分或者第二部分以最小化该位置处的结块。这样的涂层在位于分叉点处的动脉瘤中是期望的,以允许流至分支动脉的血流穿过发泡结构的具有非血栓形成涂层的区段。该涂覆区域的颜色可与可膨胀元件的剩余部分不同,从而帮助外科医生识别该区域。
可选择地,该涂覆区域还可包括不透射线材料,以帮助外科医生可视化以及在相对于该动脉瘤的期望的定向上放置该装置的部分。该装置可通过将不透射线填料添加至材料件(例如铋)或者附接不透射线标识而具有不投射线性特征。可选地,不透射线材料可(例如通过浸渍、喷涂或者以其它方式机械地、化学地或者热附接)附接至该装置、注射至或者混合至该装置中。
根据一些实施例,如果该装置具有例如旨在用于在动脉瘤的某些位置中放置的孔隙率分布、涂层、形状等的具体特征,临床医生可通过用手转动、移动或者保持在该装置膨胀时动脉瘤中的装置的位置或者以别的方式调整在该装置膨胀时动脉瘤中的装置的位置而定位该装置。因此,通过轻轻地操作该装置,临床医生可调整该装置以确保该装置在动脉瘤中合适的定向。可膨胀装置的位置可利用各种部署或者传送装置来操作。
此处所讨论的许多特征可用于所公开的实施例的任何一个。例如,任何一个实施例可包括在空间中变化的平均孔隙率、各种所公开形状的任何一种、各种所公开的材料或涂层的任何一种、所公开的2-D或3-D互连构造的任何一种、所公开的相互接合构造或结构的任何一种、所公开的传送系统的任何一种等等。
此处所讨论的设备和方法不限于在血管系统中的医疗装置或支架的部署和使用,而且可包括任何数量的其它治疗应用。其它治疗位置可包括身体的区域或部位,包括任何中空解剖结构。
