Description
技术领域
本发明涉及可植入的医疗器械,诸如支架,它们的制造、传送以及使用方法。
背景技术
支架是导入到体腔中的医疗器械,并为本领域人员所熟知。通常,支架通过所谓的“微创技术(minimally invasive techniques)”植入到心内的狭窄处或动脉瘤处的血管中,在该微创技术中,径向收缩形态(可选为通过鞘和/或导管限制成径向压缩形态)的支架被支架传送系统或“导入器”传送到所需部位。该导入器可从体外的出入口位置(例如通过患者的皮肤)进入患者体内或者通过“切除(cut down)”技术进入患者体内,该技术中进入血管通过较小的外科装置而被暴露出来。
支架、移植物、支架-移植物、腔静脉过滤器、可扩张框架以及类似的可植入医疗器械-在下文中统称为支架-是径向可扩张的内镜置管(endoprosthese),它们为通常能够穿过腔壁(transluminally)被植入并在经皮导入之后径向扩大的血管内植入物。支架可被植入到各种体腔或脉管中,诸如脉管系统、泌尿系统、胆管、输卵管、冠状血管、二级脉管等。支架可以是自扩张的、通过诸如当安装在充气球囊时的内部径向力扩张、或者是自扩张和充气球囊扩张的组合(混合扩张)。
可以制造出支架的方法包括由管状原料切削或蚀刻出设计图样,由平面片材经切削或蚀刻然后将其卷起,或者由一个或多个交织的金属丝网或编制物制成。
在脉管系统中,在脉管的分叉处形成狭窄部是很常见的。分叉处是脉管系统或者身体其他部位中第一(或主)脉管分叉成两条或两条以上支脉管的区域。在这一分叉处发生狭窄损伤或损伤,该损伤可以只是影响这些脉管中的一条
(即支脉管中的任一条或者是主脉管),这些脉管中的两条,或者是全部三条脉管。然而,需要运用支架是在与动脉或静脉分叉处(例如,哺乳动物大动脉进入髂总动脉的分叉处)并排设置的或延伸穿过该分叉的部位时,许多现有技术的支架不能完全满足使用要求。
还有需要能够向脉管分叉处提供骨架支撑的新式支架设计。

具体实施方式
尽管本发明可以许多不同形式来实施,但在此描述的为特定的较佳实施例。这一描述是本发明原理的范例,而并无意将本发明限制于所阐示的特定实施例。
为了揭示,图中相同的附图标记指向相同的特征,除非另有说明。一幅图中所示的元件在需要时可以与另一幅图中所示的元件相结合,或者被其所替代。
图1显示了支架10的一个实施例的平面展开图。图2显示了根据图1所示图案的支架10。该支架10具有近端14和远端16,并包括多个结构件,这些结构件界定出带有多个栅格12的大致管状体。这些结构件还界定出多根相交连的蛇形带20。相邻的蛇形带20通过至少一个接头36连接。
各蛇形带20包括多根由回转部30连接的柱杆22。回转部30可包括位于蛇形带20近侧的近回转部32;或可包括位于蛇形带20远侧的远回转部34。各柱杆22包括连接于近回转部32的近端52,以及连接于远回转部54的远端54。
各柱杆22还包括其近端52和远端54之间的曲线路径,并且因此包括至少一个弯23。在某些实施例中,柱杆22可包括多个弯23,诸如具有不同朝向的峰24和谷26。如果可认为峰24是从给定的基准框凸出的,则认为谷26是凹下的。拐点25可位于沿着峰24和谷26之间的曲线路径上。
柱杆22的谷26位置在连接柱杆22的远回转部34和连接柱杆22的近回转部32之中更靠近连接柱杆22的近回转部32。柱杆22的峰24位置在连接柱杆22的远回转部34和连接柱杆22的近回转部32之中更靠近连接柱杆22的远回转部34。
各柱杆22还可包括直部27。直部27可包括近直部28或远直部29。近直部28可位于柱杆22的近端52和谷26之间。远直部29可位于峰24和柱杆22的远端54之间。
柱杆22可包括第一柱杆40或第二柱杆42。第一柱杆40相对蛇形带20可与第二柱杆42交替形成。各回转部30可在一端连接至第一柱杆40并且可在另一端连接至第二柱杆42。各回转部30可还包括上部56和下部56。应当理解在这一基准框中所用的术语“上”和“下”是应用于结合支架的平面展开图所用的相对用语,并且本领域的普通技术人员应当理解该相对方位在应用于另一基准框的三维支架框架结构时可改变。
在某些实施例中,近回转部32上部56可连接至第一柱杆40的近端52。近回转部32下部58可连接至第二柱杆42的近端52。远回转部34上部56可连接至第二柱杆42的远端54。远回转部32下部58可连接至第一柱杆40的远端54。
所有的第一柱杆40界定了相似形状的曲线路径。所有的第二柱杆42界定了相似形状的曲线路径。由第一柱杆40界定的曲线路径不同于第二柱杆42界定的曲线路径。第二柱杆42上的峰24和谷26彼此之间比第一柱杆40上的峰24和谷26更靠近些。第二柱杆42的直部27比第一柱杆40的直部27更长一些。第一柱杆40的近端52可纵向地且圆周向地偏离于远端54,其中远端54可位于近端52的“上方”(如图1所示),该偏离的周缘分量(circumferentialcomponent)朝向第一方向。第二柱杆42的近端52可以纵向地且圆周向地偏离于远端54,其中远端54可位于近端52的“下方”(如图1所示),该偏离的周缘分量朝向第二方向。
第一柱杆40的近直部28和远直部29可为基本平行的。第一柱杆40的直部27可以平行于其它第一柱杆40的直部,包括共同的蛇形带20中的其它第一柱杆40和不同蛇形带20中的其它第一柱杆40。类似地,第二柱杆42的近直部28和远直部29可为基本平行的。第二柱杆42的直部27可平行于其它第二柱杆42的直部,包括共同的蛇形带20中的其它第二柱杆42和不同蛇形带20中的其它第二柱杆42。并且,第一柱杆40的直部27可以平行于第二柱杆42的直部27。
包含在蛇形带20中的所有近回转部32可相对于共同支架圆周18p对齐。包含在蛇形带20中的所有远回转部34可相对于另一共同支架圆周18d对齐。支架圆周意欲与支架中心纵轴线11成正交。
蛇形带20的所有柱杆22的所有峰24可沿着支架圆周18p基本对齐。蛇形带20的峰24沿着支架圆周18p还与相邻蛇形带20的近回转部34基本对齐。蛇形带20的所有柱杆22的所有谷26可沿着支架圆周18d基本对齐。蛇形带20的谷26沿着支架圆周18d还与相邻蛇形带20的远回转部34基本对齐。
蛇形带20的朝向为使得相邻的蛇形带20沿着支架10的长度与另一个重叠。因此,单个的共同支架圆周18a可与第一蛇形带20a以及第二蛇形带20b相交。在某些实施例中,重叠足够使共同支架圆周18a可与第一蛇形带20a的每个柱杆22以及第二蛇形带20b的每个柱杆22都相交。第一蛇形带20a的远回转部34位置可远离共同支架圆周18a,并且第二蛇形带20b的近回转部32位置可靠近共同支架圆周18a。
蛇形带20的柱杆22的谷26相对于支架圆周18可与相邻蛇形带20的远回转部34基本对齐。蛇形带20的柱杆22的峰24相对于支架圆周18可与相邻蛇形带20的近回转部32基本对齐。
各蛇形带20可横跨带长21,该带长是在平行于支架中心纵轴线11的方向测量出的。重叠的相邻蛇形带20可界定出重叠长度41,该重叠长度是在平行于支架中心纵轴线11的方向上测量出的。支架10的不同实施例可包括不同量的重叠长度41。在某些实施例中,该重叠长度41可以是带长21的10%、15%、20%、25%、30%、35%或35%以上。
根据图1所示图样制成的支架10意欲成为非螺旋型支架。当蛇形带20具有完全的圆周方位时,描绘在相邻蛇形带20之间的重叠成为现实,其中蛇形带20的圆周包括支架10的实际圆周,其中该实际圆周的方位与支架10的中心纵轴线11正交。
各蛇形带20可界定多根柱杆对38。柱杆对38包括由回转部30连接的第一柱杆40a和相邻的第二柱杆40b。因此,柱杆对38包括已连接端44和未连接端46。在某些柱杆对38中,已连接的回转部30可包括近回转部32。在某些柱杆对38中,已连接的回转部30可包括远回转部34。
一根蛇形带20的第一柱杆对38a的一部分可以容纳在相邻蛇形带20的另一柱杆对38b的一部分中。第一柱杆对38a的已连接端44可以容纳在另一柱杆对38b未连接端46处的柱杆22之间。该重叠或容纳区域可以从已连接的回转部30横跨到第一柱杆对38a的柱杆22的谷26,并且可以从未连接端46b横跨到另一柱杆对38b的柱杆22的峰24。
相邻蛇形带20被至少一个接头36连接。接头36可以从一根蛇形带20的任何适当位置横跨到另一根蛇形带20的任何适当位置。在某些实施例中,接头36可以连接于回转部30。在某些实施例中,接头36可以连接于柱杆22的一部分。
图1所示的支架10实施例包括从一根蛇形带20的回转部30横跨到相邻蛇形带20的柱杆22上的接头36。更为具体地,接头36从一根蛇形带20的远回转部34上部56横跨到相邻蛇形带20的柱杆22的谷26。
接头36可具有任何适当的尺寸和形状。在一些实施例中,与现有技术的支架交连元件相比,可认为接头36是较短的。在一些实施例中,接头36的宽度与其它支架元件的宽度相同,诸如回转部30和柱杆22。在一些实施例中,接头36的宽度可以大于其长度。
蛇形带20可在连接至支架10的其它部分的各点之间,诸如第一连接点65和第二连接点66之间,界定出自由柱杆长度64。在一些实施例中,连接点65、66是蛇形带20连接于接头36之处。在一些实施例中,第一连接点65包括与沿支架10长度靠近该蛇形带20的支架结构的连接,并且第二连接点66包括与沿支架10长度远离该蛇形带20的支架结构的连接。自由柱杆长度64可包括多根柱杆22和多个回转部30,并且在一些实施例中,可包括四个回转部30和至少四根柱杆22。自由柱杆长度64也可描述为蛇形带20的未支撑长度或蛇形带20的未连接长度。
在某些实施例中,连接点65、66之间沿自由柱杆长度64的横向总距离等于或大于支架10的圆周18。在各种实施例中,当柱杆处在名义上的扩张状态(即在被制造或被激光切割时)及/或当柱杆处在蜷曲或扩张传送状态时,这一情形得以实现。
自由柱杆长度64界定了圆周长度分量68,或者以圆周方向测量的连接点65、66之间的距离。针对各种自由柱杆长度64,可以描述“自由柱杆长度:圆周长度分量”之比。在各种实施例中,该比例可以是:1∶1,2∶1,7∶3,3∶1,4∶1,5∶1或更大。对于图1示出的所标记的自由柱杆长度64,该比例预期为约4.67∶1。为了测量自由柱杆长度64和圆周长度分量68,图1可以认为是按比例绘制的支架10一些实施例的图。
自由柱杆长度64界定了多个拐点区62,各拐点区62包含蛇形带20的凹度产生变化的拐点25。自由柱杆长度64可包括任何适当数量的拐点区62,并且在一些实施例中可包括5、7或9或更多的拐点区64。例如,图1的自由柱杆长度64的实施例标有9个拐点区62。
图2显示了根据图1所示图样形成的、处于蜷曲或传送状态中的支架10。该支架10能够有高扩张量。
图3显示了图2的支架10处于第一扩张状态。第一扩张状态下支架10的直径约为传送状态下支架10的直径的1.9倍。相邻蛇形带20沿支架10的长度连续重叠。单个共同支架圆周18a可连续与第一蛇形带20a和相邻的第二蛇形带20b相交。在一些实施例中,具有足够的重叠,使得共同的支架圆周18a与第一蛇形带20a的每个柱杆22以及第二蛇形带20b的每个柱杆22都相交。
图4显示了图2的支架10处于大于第一扩张状态的第二扩张状态。第二扩张状态下支架10的直径约为传送状态下支架10的直径的2.7倍。即使在该第二扩张状态,单个共同支架圆周18a也可连续与第一蛇形带20a和相邻的第二蛇形带20b相交。
支架10能够扩张到远大于图4所示的第二扩张状态。在支架10的一些实施例中,“蜷曲直径∶扩张直径”的比例高达1∶5.1或更高,同时支架10保持适当的形状和功能,并且能为脉管壁提供足够的骨架支撑。因此,支架若没有变成“过度扩张”,该扩张比可以实现。应当注意,本文描述的支架10能够以轴向相对缩短10%或以下来进行这一扩张。此外,引述的支架直径通常可认为是支架的外径(即,蜷曲外径∶扩张外径),然而,在一些实施例中,文中作出的陈述可描述内径(即,蜷曲内径∶扩张内径)。
该支架10还能够沿其长度具有不同程度的扩张量。例如,支架10的第一部分可以根据图4进行扩张,而支架10的第二部分可以扩张到更大的程度。该第一部分和第二部分可以沿支架10的长度彼此直接相邻。从而,支架10在脉管分叉处特别有用。
该支架10还特别适用于儿童。随着儿童年龄增大和体内脉管的生长,先前植入的支架可能需要一次或多次的附加扩张手术。该支架10的高扩张能力可以让支架10用于原先所需的更大的第二替代支架的场合。
图5显示了支架10在主脉管70中靠近分叉处的方位。支架10处在基本等于第二扩张状态的扩张状态,例如图4所示的状态。该支架10的直径/尺寸大体等于主脉管70的直径/尺寸71。
支架10包括可扩张到侧支脉管72中以支撑侧支脉管72的结构,例如如图6所示。该适当的结构可以例如使用具有第一和第二可充气部的球囊进行扩张。第一可充气部可用于扩张支架10的主圆柱框架。可独立于第一可充气部充气的第二可充气部可用于将一部分支架结构扩张到侧支脉管72中。
在一些实施例中(未显示),支架10可设有侧支开口,以容置第二支架。支架10可定位在主脉管70中,同时侧支开口定位在侧支脉管72的附近。第二支架可定位在侧支脉管72中并与主支架10相结合。
图6显示了图5的支架10,其中支架10的第一部分76保持在第一扩张状态,而第二部分78已进一步扩张到侧支脉管72中。延伸到侧支脉管72中的支架结构向对侧心门壁(contralateral ostial wall)74提供了支撑。第二部分78的区域中的支架10扩张到大于主脉管70的尺寸73。因此,第一蛇形带20c可在主脉管70中扩张成第一扩张状态,并且第二蛇形带20d可部分地扩张到侧支脉管72中成更大的第二扩张状态,其中该第一蛇形带20c和第二蛇形带20d沿着支架的长度彼此直接相邻。第一蛇形带20c的实体部可位于隆线80的一侧,同时第二蛇形带20d的实体部可位于隆线80的另一侧。
任何蛇形带20的任何适当部分都可扩张到侧支脉管72中。因此,不同于现有技术中带有特定和专用侧支结构的支架,发明的支架10不需要被放置成相对于侧支脉管72具有特定的旋转方位。支架10可根据合适的长度方位简单地放置,并且蛇形带20上因此朝向侧支脉管72附近的部分可以扩张到侧支脉管72中。支架10还可适用于具有一个以上分叉的脉管位置。
在一些情况下,会需要专用的侧支结构。图7显示了包括第一部分84和第二部分88的支架10实施例的平面展开图样。第一部分84可包括重叠的蛇形带20和如文中所述,例如,参考图1的支架结构。第二部分88可包括任何适当的支架结构以及局部侧支结构96。
第二部分88的支架结构可包括蛇形带116和接头柱杆120的图样。该蛇形带116可包括通过回转部128连接的交替的直柱杆93和S形柱杆94,例如参考美国专利申请第11/262,692号所披露的各种柱杆实施例所描述的,通过整体引用而将该美国申请的全部公开内容合并在此。
局部侧支结构96可包括任何合适的支架侧支结构,并且在一些实施例中可包括多个可向外展开的瓣形结构98。例如,在美国专利申请公开第20050060027号中描述了支架侧支结构的实例,通过整体引用而将该美国申请的全部公开内容合并在此。
该局部侧支结构96可认为是“局部”结构,因为其不试图在完整的360度上支撑该侧支脉管,并且因此,该局部侧支结构96与现有技术中通常所示的“完整”侧支结构相比是缩短了。如图7所示,局部侧支结构96延伸约为180度,并且因此可认为是半冠结构。
当图7的支架10在脉管分叉处扩张时,第一部分84可延伸到侧支脉管72中并支撑对侧的心门壁74(见图6)。该局部侧支结构96可展开到隆线80附近的侧支脉管72中。因此,支架10的第一部分84支撑了侧支脉管72的第一部分,并且局部侧支结构96支撑了侧支脉管72的第二部分,这样各部分84、96大致提供了该侧支脉管72的全部支撑的一半。因此,第一部分84支撑与局部侧支结构96支撑之比约为50∶50。支架10的各实施例可包括由各部分84、96向侧支脉管72提供的支撑量之间的任何适当分配比。例如,支架10的各实施例可具有的支撑比为:55∶45,60∶40,65∶35,70∶30等,以及45∶55,40∶60,35∶65,30∶70等。
在支架10的各实施例中,第一部分84的支架图样可比图7所示的结构包括整个支架结构中更多的部分或更少的部分。例如,在一些实施例中,第一部分84可包括两或三根蛇形带20位于与局部侧支结构96直接相邻处。较佳地,第一部分84所跨越的支架轴向长度等于或大于局部侧支结构96所跨越的支架轴向长度。在一些实施例中,支架10可在第一部分84的近侧和远侧都包括第二部分88的结构。此外,局部侧支结构96和第一部分88的配对可位于沿支架10长度上的任何位置,并且在一些实施例中,如图7所示是处于大致中间位置。
图8显示了支架10的另一实施例的平面展开图样。该支架10包括多根例如参考图1所述的蛇形带20。该支架10还包括局部侧支结构96和至少一根局部蛇形带82。局部蛇形带82不绕着支架10的整个圆周延伸,并且基本上与局部侧支结构96连接。
支架结构可使用任何适当的方法扩张到侧支脉管中。在一些实施例中,例如美国专利申请公开第20050060027号中所述的具有第二可扩张部分的球囊,可以用来扩张第二部分78(见图6)和局部侧支结构96中任意一个或两个。自扩张实施例也可以是较合意的,因为它们会自行扩张到侧支脉管中。
图9显示了支架10的另一实施例的平面展开图样,其中端部设置的结构框架图样与中部的不同。在一些实施例中,支架10包括第一部分49、第二部分50和第三部分51。各部分49、50、51可以占据支架10不同的长度部分。例如,第二部分50可包括中间部。第一部分49可从支架10的近端14横跨至第二部分50。第三部分51可从第二部分50横跨到支架10的远端16。
在一些实施例中,第一和第三部分49、51可包括与第二部分50的支架结构不同的支架结构。例如,第一和第三部分49、51可各包括彼此隔开的蛇形带116,并且第二部分50可包括彼此重叠的蛇形带20。在一些实施例中,位于第一和第三部分49、51中的各蛇形带116占据了支架10上分离且不同的长度部分。
较佳地,第二部分50包括,例如参考图1所述的,蛇形带20和具有高扩张性能的接头36。
第一部分49和第三部分51可各包括任何适当的支架结构。在一些实施例中,第一和第三部分49、51可以是彼此相似的形状。在某些实施例中,第一和第三部分49、51可以彼此不同。
在一些实施例中,第一部分49和/或第三部分51可以包括多根蛇形带116和多个接头柱杆120。各蛇形带116包括多根带柱杆122和多个回转部128。当横穿蛇形带116时,带柱杆122和回转部128可交错。该回转部128可包括交替的近峰124和远谷126。各近峰124大体上相对于支架10的近端14为凸出,并且相对于支架10的远端16为凹入。各远谷126大体上相对于支架10的远端16为凸出,并且相对于支架10的近端14为凹入。
各部分49、51可具有任意合适数量的蛇形带116。在各个实施例中,蛇形带116可具有任意合适数量的带柱杆122和任意合适数量的回转部128。各蛇形带116可沿支架10的长度跨越任意合适的距离。在一些实施例中,支架10可以包括跨越不同距离的蛇形带116。增加蛇形带116长度方向跨度的一种方法是增加带柱杆122的长度。
沿部分49、51的长度彼此相邻的蛇形带116由至少一个接头柱杆120连接。在一些实施例中,接头柱杆120跨越在相邻蛇形带116的回转部128之间。在一些实施例中,接头柱杆120可包括第一种接头柱杆136和第二种接头柱杆138。第一接头柱杆136以第一方向延伸。第一接头柱杆136可与支架长度方向轴线11成第一角度。第二接头柱杆138以不同于或不平行于第一方向的第二方向延伸。第二接头柱杆138可与支架长度方向轴线11成第二角度。
在一些实施例中,部分49、51上位于两相邻蛇形带116之间的区域可以认为是接头列144。各接头列144包括多根接头柱杆120。在一些实施例中,接头列144中的各接头柱杆120可以彼此是相似的。例如,第一接头列144a中的各接头柱杆120可以包括第一种接头柱杆136。第二接头列144b中的各接头柱杆120可以包括第二种接头柱杆138。在一些实施例中,第一接头列144a和第二接头列144b可以沿部分49、51的长度交错设置。
回转部128可包括已连接的回转部158或未连接的回转部155,这取决于回转部128是否连接到接头柱杆120。
可适用于任意一个部分49、51的支架结构的其它实例揭示在美国专利申请公开第2002/0095208号和美国专利申请第11/262692号中。
支架10还包括第一部分49和第二部分50之间的第一过渡区87,以及第二部分50和第三部分51之间的第二过渡区89。各过渡区87、89可以包括至少一个在该过渡区87、89的任意一侧连接于支架结构的过渡接头97。例如,第一过渡区87的过渡接头97可在一端连接于第一部分49的支架结构,并且可在另一端连接于第二部分50的支架结构。
在一些实施例中,任意一个过渡区87、89可包括单过渡接头97。在一些实施例中,过渡区87、89可包括多个过渡接头97。
在一些实施例中,第一过渡区87中的过渡接头97可包括与第二过渡区89中的过渡接头97相同的形状。在一些实施例中,第一过渡区87中的一个或一个以上的过渡接头97可包括与第二过渡区89中的过渡接头97不同的形状。
在一些实施例中,过渡接头97沿其长度可以是直的。在一些实施例中,过渡接头97可与支架纵轴线11成一角度。
图9所示的支架10可以在脉管分叉处展开,例如如图13和图14所示。第二部分50的蛇形带20设计成沿支架10的长度有重叠,并且具有较长的未受支撑的柱杆长度。因此,第二部分50的蛇形带20能够扩张到支脉管72中,并且同时支撑主脉管70和支脉管72,例如支撑对侧的心门壁74。
第一和第三部分49、51的蛇形带116包括与第二部分50相比更为常规的结构图样。通常,第一和第三部分49、51的结构提供了比第二部分50更大的抵抗径向变形的阻力,但能更小地扩张的程度。因此,第二部分50构造和设置成扩张到侧支脉管72中,同时第一和第二部分49、51在脉管分叉处的任意一侧上提供了用以支撑主脉管70的更大强度。
图10显示带有第二部分50的支架10的另一实施例的平面展开图样,该第二部分50包括与第一和第三部分49、51不同的结构框架图样。在一些实施例中,支架10还包括多个附加物60。该附加物60可构造和设置成支撑脉管分叉处的隆线,诸如以下参考图13和图14所述。
在一些实施例中,附加物60包括未受支撑端或自由端61。在一些实施例中,附加物60在已连接端57连接至蛇形带116,例如第一部分49的蛇形带116,并且沿其长度是未受支撑的。因此,在一些实施例中,附加物60仅在单个已连接端57处可以连接至其它的支架框架,并且可以包括悬臂型结构。
附加物60可以位于过渡区87、89中。在一些实施例中,支架10包括在第一过渡区87中的附加物60,如图10所示。在一些实施例中,支架10可在第一和第二过渡区87、89中都包括附加物60。
在一些实施例中,附加物60可以连接于第一部分49的蛇形带116并且延伸到第二部分50中。在一些实施例中,附加物60和第二部分50的至少一根蛇形带20的柱杆22可以相对于共同的支架圆周重叠。在一些实施例中,附加物60在已连接端57连接于第一部分49的蛇形带116的近峰124,并且朝支架10的远端16延伸穿过第一过渡区87。
在一些实施例中,附加物60可以是直的。在一些实施例中,附加物60可以包含曲线,例如包括弯67。在一些实施例中,附加物60可包括多个弯67。在一些实施例中,附加物60可包括一个或多个与支架纵轴线11平行的部分。在一些实施例中,附加物60可包括至少一个与支架纵轴线11成一角度的部分。
在一些实施例中,附加物60的宽度沿其长度是不变的。在一些实施例中,附加物60的宽度大致等于支架10的蛇形带20、116的柱杆22、122的宽度。在一些实施例中,附加物60的宽度可接近支架10的蛇形带20、116的柱杆22、122的宽度,例如包括柱杆宽度的80-120%。
在一些实施例中,附加物60可包括比起支架10其它部分为射线更透不过的材料,例如包括射线透不过的标志。射线透不过的附加物60可有助于支架的放置。
图11显示了带有第二部分50的支架10的另一实施例的平面展开图样,该第二部分50包括与第一和第三部分49、51不同的结构框架图样。在一些实施例中,支架10还包括多个附加物60。在一些实施例中,支架10还包括多个横跨在附加物60之间的连接部件79。在一些实施例中,连接部件79在一端连接于附加物60,而在另一端连接于圆周向相邻的附加物60。
连接部件79可位于过渡区87、89中。在一些实施例中,连接部件79可支持附加物60以防止变形,诸如在支架扩张/展开过程中在切向中的变形。
在一些实施例中,附加物结构可包括蛇形结构85。在各实施例中,蛇形结构85的峰和谷可以有角度或者是弯曲的,并且蛇形结构85可包括波浪形或之字形结构。该附加物结构可进一步包括连接柱杆91和附加物尖端柱杆95。连接柱杆91可将蛇形结构85连接到位于第二部分50之外的支架结构,诸如第一部分49的蛇形带116上。在一些实施例中,连接柱杆91可以在一端连接于蛇形带116的近峰124,并且可在另一端连接于蛇形结构85。附加物尖端柱杆95可以连接于蛇形结构85并且可进一步包括自由端61。
图12显示了带有第二部分50的支架10的另一实施例的平面展开图样,该第二部分50包括与第一和第三部分49、51不同的结构框架图样。在一些实施例中,附加物60可包括峰69。在一些实施例中,附加物60可在一端连接于蛇形带116,诸如位于第一部分49中的蛇形带116的柱杆122。附加物60可延伸穿过第一过渡区87进入第二部分50,并且通过第一过渡区87转回,并延伸返回到第一部分49中。附加物60的第二端可以然后连接于另外的支架结构,诸如蛇形带116、圆周向相邻的附加物60等。
图13显示了扩张操作过程中位于脉管分叉处的支架10的实施例。支架10可以放置在主脉管70中,同时第二部分50与支脉管72对齐。较佳地,例如当支架10包括附加物60时,第一过渡区87可以放置成与分叉处的隆线80纵向对齐。较佳地,支架10的第一部分49可以位于分叉处的近侧,并且支架10的第三部分51可以位于分叉处的远侧。
支架10可以使用任何合适的方法,诸如充气球囊15,在主脉管70中扩张。在一些实施例中,充气球囊15可包括能将第二部分50的蛇形带20扩张到支脉管72中的突出部19。当支架10包括附加物60时,较佳地,球囊15也将一个或多个附加物60扩张到支脉管72中。具有突出部的球囊的例子如美国专利申请公开20060036315所述,通过引用将其整份说明书合并在此。其它适当的球囊例子,诸如具有辅助可充气部的球囊,在美国专利申请公开20050060027中被公开,如前所述。在一些实施例中,球囊15可包括顺应性球囊。在一些实施例中,球囊15可包括带有顺应性外层或环绕有顺应性球囊的非顺应性球囊,其中该非顺应性部分使支架10扩张到主脉管70中,并且顺应性层或部分进一步扩张将蛇形带20扩张到支脉管72中。在一些实施例中,球囊15可包括具有扩张到支脉管72中的部分的半顺应性球囊。在如图13所示的扩张完成后,球囊15可以去除。
图14显示了图13的支架10进一步扩张的状态。在一些实施例中,在参考图13所述的扩张之后,导线可通过分叉处放置到支脉管中,并用于引导第二球囊31进入分叉处。在各实施例中,第二球囊31可为顺应性球囊或非顺应性球囊。在一些实施例中,第二球囊31可以设有用以支撑支脉管72的第二支架(未示出)。
第二球囊32可以被充气,将第二部分50的蛇形带20进一步扩张到支脉管72中并抵靠住对侧的心门壁74。第二球囊31还可形成隆线80周围的附加物60,从而向隆线80提供支架支撑。
在一些实施例中,支架10可以蜷曲或缩小到传送尺寸,让蛇形带20的一部分在支架径向重叠到附加物60。因此,在支架传递过程中,蛇形带20可用于重叠和保护附加物60。在一些实施例中,支架10的尺寸可以分为两个步骤来缩短。首先,支架10的第一部分49,连同附加物60,可以缩短尺寸。接着,支架10的剩余部,包括第二部分50,可以缩短尺寸。在一些实施例中,蛇形带20最靠近第一过渡区87的部分会重叠附加物60的部分。
在一些实施例中,支架10可以是自扩张的,例如由形状记忆材料,诸如镍钛合金制成。
当自扩张支架10包括在不同区域49、50、51中的不同蛇形带20、116图样时,例如如图9-12所示,第二区域50中的蛇形带20可以设置成自扩张到比端部区域49、51的蛇形带116更大的尺寸。例如,任意一个端部区域49、51的蛇形带116可以被热设定成扩张到名义扩张直径d,并且第二区域50的蛇形带20可以被热设定成扩张到更大直径,诸如1.1d;1.25d;1.5d;1.75d;2d等。因此,第二区域50能够扩张进入到支脉管。
本发明还涉及将在此所述的支架10传送到展开位置的方法,并且将支架结构在主支脉管内扩张并扩张到侧支脉管中,正如本领域技术人员所能理解的。
在一些实施例中,支架、传送系统或组件的其它部分可包括一个或多个区域、带、涂层、部件等可以被成像模式,诸如X光、MRI、超声等检测到。在一些实施例中,至少一部分支架和/或相邻组件是至少部分射线透不过的。
在一些实施例中,至少一部分支架配置成包括一个或多个传送治疗药剂的机构。药剂经常会以涂层或其它材料层的形式设置在支架的表面区域,这样可适于在支架的植入部位置或其邻近区域进行释放。
当支架10包括在不同区域49、50、51中的不同蛇形带20、116图样时,例如如图9-12所示,第二区域50可具有更密集的柱杆图样,并且因此单位面积内的结构材料量比端部区域49、51更多。因此,在密集度较低的区域施加更多的治疗药剂可以是较佳的。
向区域49、50、51的各个区域提供不同量的治疗药剂也可以是较佳的。例如,第二区域50的局部区域,诸如期望延伸到支脉管72中的区域,可以包括更高浓度的治疗药剂。
在一些实施例中,支架10可以包括可充填治疗药剂的储室。例如,通过蚀刻和/或激光切除,在支架内可形成储室、凹槽和/或其它适当区域。该储室可用任何适当技术进行充填。
在一些实施例中,治疗药剂可采用网线辊(Anilox rolling)技术来施加。在美国专利5989639;6006665和6312367中描述有网线辊,这些内容通过引用将其全部合并在此。
在一些实施例中,治疗药剂可使用可通过德国Microdrop技术有限公司(Microdrop Technologies GmbH,Muehlenweg 143,D-22844 Norderstedt,Germany)生产的机器,诸如其AD、MD或MJ系列分配系统来施加。
在一些实施例中,治疗药剂可使用可通过爱尔兰Labcoat有限公司(LabcoatLimited,Ballybrit Business Park,Unit 4,Galway,Ireland)生产的机器,诸如适用于其特有的Juxtaposed Ablumenal(JATM)涂层及处理工艺的机器。
在一些实施例中,治疗药剂可使用喷墨打印技术来施加。在一些实施例中,治疗药剂可根据美国专利6676987所公开的方法来施加,通过引用将其整体合并在此。
在一些实施例中,治疗药剂可使用直接写技术来施加,例如美国专利4485387所公开的,通过引用将其整体合并在此。直接写装置可例如从Ohmcraft有限公司(Ohmcraft,Inc.,93Paper Mill Street,Honeoye Falls,NY 14472.)获得。
在一些实施例中,可于第二部分50上施加一层治疗药剂,并且于第一和第三部分49、51上施加多层药剂。
在一些实施例中,射线透不过材料可施加在支架的多个部分上,诸如附加物60上。在一些实施例中,可在支架10上同时施加射线透不过材料和治疗药剂。例如,网线辊的雕刻单元可交替提供治疗药剂和射线透不过材料,并且两者可施加到支架10的局部区域。
治疗药剂可为药物或其它药用制品,诸如非遗传药剂(non-genetic agents)、遗传药剂、细胞材料(cellular material)等。适当的非遗传治疗药剂的一些例子包括但不限于:抗血栓剂,诸如肝素,肝素衍生物、血管细胞生长促进剂、生长因子抑制剂、红豆杉醇等。当药剂包括遗传治疗药剂时,此遗传药剂可包括但不限于:DNA、RNA及其各自的衍生物和/或成分;刺猬蛋白等。当治疗药剂包括细胞材料时,该细胞材料可包括但不限于:人类起源的细胞和/或非人类起源的细胞,以及它们各自的成分和/或衍生物。当治疗药剂包括聚合物药剂时,该聚合物药剂可为聚苯乙烯-聚异丁烯-聚苯乙烯三嵌段共聚物(SIBS),聚环氧乙烷,硅橡胶和/或任何其它合适的基材。
上述说明的意图是用于阐述而非穷举的。该描述对于本领域普通技术人员会有许多变化和替代的启示。个别附图中显示的以及以上所描述的各个元件在需要时可以组合或为了组合而作改动。所有这些替代和变化意欲包含在权利要求的保护范围中,其中术语“包括”意味着“包含但不限于”。
还有,从属权利要求中出现的具体特征可以用本发明范围内的其它方式互相合并,从而应当承认本发明,还明确地涉及其它具有从属权利要求特征的任意可能组合的实施例。例如,为了权利要求的公布,下列任何从属权利要求应当可以采用多项从属形式的另一种写法,即其从属于所有的、具有该从属权利要求所引用的全部前提条件的在先权利要求,如果该多项从属的格式在法律范围内是可接受的格式的话(例如,每个直接从属于权利要求1的权利要求,应当换成从属于所有在先的权利要求的写法)。如果法律限制多项从属权利要求的格式,下列从属权利要求应当分别采用另一种写法,即从属于在先的、具有前提条件的权利要求的各单一的从属权利要求格式,而不是以下从属权利要求中所列出的具体权利要求。
