Description

可选择膨胀的骨支架
技术领域
本发明总的来说涉及可以插入到骨中的可膨胀装置。更具体地说,本发明涉及可选择地膨胀的骨支架。
背景技术
小型组织插入物和小型展开工具允许通过某些最小侵入方法进入目标组织部位。当在目标组织部位内展开时,这种工具可以呈现扩大的、坚固的形状。这允许皮层骨以所希望的方式排出,和/或在网状骨中形成空腔,不会过度膨胀、刺穿和/或磨损结构。工具可以留在骨内部,以在工具膨胀之后为骨提供附加支撑。
这些已知的可膨胀工具可以,例如,压实网状骨以固定骨折,或者改善人骨和兽骨的其它骨质疏松状态和非骨质疏松状态。但是,由于工具在结构中具有间隙,这些已知装置或者缺乏足够的方向控制,或者对骨结构不能提供相容的压实或分散。
因而,需要对设置在骨中的可选择膨胀结构进行改进。
发明内容
一种设备,其包括构造成设置在组织(例如骨、脊椎骨、椎间盘等)中的支架。该支架构造成从第一构造移动至第二构造。处于第二构造的支架从第一构造膨胀。可选择地膨胀的致动器构造成可移除地设置在支架内部。可选择地膨胀的致动器构造成,当其移动至膨胀构造时,使支架的至少一部分移动至第二构造。当可选择地膨胀的致动器处于膨胀构造并且支架处于第二构造时,可选择地膨胀的致动器的形状基本上与支架的形状相同。可选择地膨胀的致动器构造成当其处于收缩构造时从支架上移除。在支架被致动器膨胀之后,支架构造成大体上保持在第二构造。

具体实施方式
一种设备,其包括构造成设置在组织(例如骨、脊椎骨、椎间盘等)中的支架。该支架构造成从第一构造移动至第二构造。处于第二构造的支架从第一构造膨胀。可选择地膨胀的致动器构造成可移除地设置在支架内部。可选择地膨胀的致动器构造成,当其移动至膨胀构造时,使支架的至少一部分移动至第二构造。当可选择地膨胀的致动器处于膨胀构造并且支架处于第二构造时,可选择地膨胀的致动器的形状基本上与支架的形状相同。可选择地膨胀的致动器构造成当其处于收缩构造时从支架上移除。在支架被致动器膨胀之后,支架构造成大体上保持在第二构造。
支架构造成当移动至膨胀构造时可塑性变形。一旦支架变形,它的位置就保持在所设置的身体内部(即,骨)。塑性变形指的是材料在不断裂的情况下形状和/或尺寸由于超过材料的弹性极限的应力维持一段时间而引起的永久改变。
在此使用的术语″支架″是指构造成设置在骨例如椎骨内部的可展开装置。支架可以随意地移动其所设置在的身体结构的一部分(例如椎骨内的网状骨)。不管支架在展开时是否改变身体结构的位置,支架都可以保持或者帮助保持身体结构的形状和/或位置。
支架构造成在已经移除可选择地膨胀的致动器之后大体上保持在第二构造。在这里,术语″大体上″指的是支架保持在骨中时可能遭受一些微量的压缩(例如形状和/或位置发生改变)。
在此使用的术语″可选择地膨胀的致动器″是指在一段时间内周期地和/或随机地膨胀和收缩的致动器。另外,致动器可以间歇地膨胀和/或通过改变膨胀和收缩的程度来膨胀。例如,致动器不一定完全膨胀或完全收缩。
图1是依照本发明实施例的医学装置10的示意性剖视图。该医学装置包括构造成设置在骨(未示出)中的支架20。支架20构造成在如图1中实线所示的第一构造与如图1中虚线所示的第二构造之间移动。支架20在第一构造收缩,在第二构造膨胀。
可选择地膨胀的致动器30构造成可移除地设置在支架20内部。可选择地膨胀的致动器30构造成,当可选择地膨胀的致动器30移动至膨胀构造时,使支架20的至少一部分移动至第二构造。
当可选择地膨胀的致动器30处于膨胀构造以及支架20处于第二构造时,可选择地膨胀的致动器30的形状基本上与支架20的形状相同。另外,可选择地膨胀的致动器30和支架20可以同心地和/或同轴地对齐。
在可选择地膨胀的致动器30将支架20移动至第二构造之后,可选择地膨胀的致动器30返回至其收缩构造,并可以从支架20上移除。支架20构造成在已经移除可选择地膨胀的致动器30之后在骨内部大体上保持在第二构造。可选择地膨胀的致动器30必须仅仅收缩一足够的程度才能从支架20上移除。换句话说,收缩构造可以是允许可选择地膨胀的致动器30插入支架20中和/或从支架20上移除的任何构造。
当支架20处于第一构件时,支架20可以经皮插入到身体中,并穿过骨。当支架20移动至第二构造之后,支架20保持在骨内部。
支架20移动至第二构件时塑性变形。换句话说,支架20的机械性能发生变化,使得支架20不能回复至其初始构造。支架20的几何形状被永久改变。
当支架20在椎骨中膨胀(即,移动至其第二构造)时,支架20构造成在椎骨的网状骨中膨胀一定体积。该体积可以通过例如压实网状骨和/或移动并随后抽取网状骨或其它生物材料试样得以形成。当致动支架时,医学装置10能够通过提供横穿支架20的力来压实骨。支架20被可膨胀的致动器30展开。
在有些实施例中,可选择地膨胀的致动器30包括气囊。气囊可以关于气囊的纵向轴线对称或不对称。气囊构造成通过例如液体和/或气体膨胀。
医学装置10包括耦联于支架20的轴50。轴50构造成沿图1中箭头X-X所示的远离支架20的方向移动。轴50用于将医学装置10插入到骨中,其在支架20膨胀到第二构造之后被移除。在有些实施例中,轴50可以是限定通路或工作通道55的插管。
支架20可移除地耦联到轴50上。在展开支架20之前,轴50可用作填充管。填充材料可以通过放置在椎骨内部(例如邻近网状骨)的支架20的缝隙注入。轴50的工作通道55还可以用作用于另外的工作工具的通路。
轴60构造成可移除地插入在由轴50限定的通路55内。为了从支架20内部移除可选择地膨胀的致动器30,轴60可以沿箭头Z所示的方向退出医学装置10。
图2是医学装置10′的透视图,医学装置10′包括依照发明实施例的骨支架20′。如图2所示,支架20′沿其长度包括多个卵形缝隙15。当支架20′处于膨胀构造时,各个缝隙15的形状影响支架20′的形状。缝隙15可以关于支架20′的圆周对称或不对称。当致动器(在图2中未显示)膨胀时,支架20′在骨内部膨胀。在有些实施例中,当支架和致动器移动至各自的膨胀构造时,支架20′和致动器(未显示)压实网状骨。
支架20′可移除地耦联于轴50′,轴50′可用作例如插管。一旦支架20′膨胀,就可以从支架20′上移除轴50′,使支架20′留在骨中。
图3是医学装置10″的透视图,医学装置10″包括依照本发明进一步的实施例的骨支架20″。支架20″包括多个绕支架20″的圆周设置的线22。在有些实施例中,线22被致动器例如气囊致动器膨胀到椎骨的网状骨内。然后移动支架20″(例如旋转地和/或横向地),这样,线切割网状骨,并移除网状骨,从而改变由医学装置10″在椎骨中形成的体积。
图4-6示出了图2中医学装置10′处于各种构造时的侧视图。图4是医学装置10′处于第一构造时的侧视图。如上所述,在被插入到骨例如椎骨中之前,医学装置10′处于第一构造。在有些实施例中,当被插入到骨中时,可选择地膨胀的致动器30′设置在支架20′内部。在有些实施例中,可以首先将支架20′插入骨中,然后通过由轴50′限定的通路将可选择地膨胀的致动器30′插入到支架20′的内部。
图5是医学装置10′处于第二构造时的侧视图,可选择地膨胀的致动器30′设置在支架20′内部。当可选择地膨胀的致动器30′使支架20′膨胀时,在位于医学装置10′周围的网状骨内部限定了一体积。在有些实施例中,网状骨被致动器30′和支架20′压实。
图6是设备10′在可选择地膨胀的致动器30′已经从支架20′上移除之后处于第二构造时的侧视图。一旦可选择地膨胀的致动器已经从支架20′上移除,就可以从支架20′上移除轴50′,而支架20′保持在骨中。
轴50′通过已知的连接件可移除地耦联于支架20′。例如,轴50′可以利用螺纹接头、分离连接件、锁连接和键连接等等与支架20′耦联在一起。假如一旦支架20′定位在骨中并膨胀,轴50′就可以从支架20′上移除,任何适当的连接装置都是合适的。
图7是依照本发明另一个实施例的支架20在处于第一构造时的其一部分的侧视图。图8是图7所示的支架20部分处于第二构造时的侧视图。在有些实施例中,缝隙25沿支架20限定,使得当支架20被致动器(未示出)如上所述膨胀时,支架20移动至如图8所示的第二构造。在第二构造,多个空隙27形成在支架20的相邻部分之间。
如图7所示,开口17限定在各个缝隙25的一端。当支架20移动至第二构造时,支架20沿其长度均匀地膨胀。支架20越长,直径在用于制造支架20的材料的应力极限之内的可能改变就越大。例如,如果材料在开口17可以容许三度的分离(three degrees ofseparation),对相同的三度容差来说,更长的支架20可以引起更大直径变化。
在替换配置(未显示)中,多个支架20可以彼此同心地(即一个在另一个内部)定向。另外,同心定向的支架20可以彼此相对旋转,使得一个支架20的缝隙17与另一个支架20的缝隙17不同相(即,不完全重叠)。在这样的构造中,当支架20被膨胀时,空隙27的尺寸一起减小,支架组合(即,内部支架20和外部支架20)的强度增加。支架20可以焊接在适当位置,以保持它们的相对位置。
当支架20同心定向然后被膨胀时,内部支架20部分向外膨胀,同时外部支架20部分向内收缩。各个支架20的相邻部分基本上阻止剩余的支架20在外压力作用下收缩。这种支架20可以由例如形状记忆材料形成,形状记忆材料在收缩构造被插入,在插入到椎骨体中之后被膨胀。
图9-11显示了医学装置100,包括具有第一部分210和第二部分220的支架200,第一部分210和第二部分220可一起在第一收缩构造(见图10)与第二膨胀构造(见图11)之间移动。第一部分210和第二部分220实际上是截然不同的第一部分210构造成当支架200处于第一构造时接触第二部分220。当支架200移动至第二构造时,第一部分210与第二部分220间隔开,如图11所示。
致动器130可移除地耦联于支架200。该致动器130构造成使支架200从第一构造移动至第二构造。套筒300绕支架200设置。套筒300构造成朝着支架200的第二部分220偏压支架200的第一部分210。在有些实施例中,套筒大体上是弹性的。当致动器130向外的压力足够时,向外的压力克服套筒300的弹性力。可改变套筒300的性能,使得在致动时,支架200的第一部分210以与支架200的第二部分220不同的比率膨胀。换句话说,支架200可以各向异性地膨胀。
在图12-14中显示了依照本发明实施例的医学装置500。图12是医学装置500处于第一构造时的侧面剖视图。图13是图12所示的医学装置500处于第二构造时的侧面剖视图。图14是依照本发明实施例的医学装置500处于第二构造时的透视图。
如图12-14所示,支架520具有大体上螺旋形的形状。如图12和13所示,当可选择地膨胀的致动器530移动至第二构造时,只有与致动器530接触的支架520部分522才移动至第二构造,不与致动器接触的支架520部分524不移动至第二构造。
支架520可以弹性变形或者可以塑性变形。另外,可选择地膨胀的致动器530可以均匀地膨胀或者可以非均匀地膨胀,以便处于第二构造的支架520的形状可以沿着其长度变化。
尽管上面已经描述了本发明的各种各样的实施例,但是,应当理解,这些实施例仅仅作为例子,不作为限制。因而,本发明的外延和范围不应当由上述任何实施例来限定,而是应当仅仅依照下列权利要求及其等效物来限定。
虽然已经参照实施例具体显示和描述了本发明,但是,本领域技术人员应该理解,在没有背离本发明的精神和范围的情况下,在形式和细节方面可以对此进行各种各样的改变。
例如,虽然可选择地膨胀的致动器30、30′、130、530描述为单个气囊,但是,在替换实施例中,可以在支架内部之间设置多个单独的致动器。例如,致动器可以包括被单独致动以容许各向同性地展开支架的多个腔。
虽然没有参照具体材料描述支架,但是,支架可以由足以插入身体组织中并足以改变组织体积的任意材料制成。例如,支架可以由镍钛诺或不锈钢制成。
虽然可选择地膨胀的致动器30如上所述耦联于单独的轴60,但是,在替换实施例中,致动器30可以与支架20一起耦联到同一轴50上。在这样的构造中,当轴50被分离并从支架20上移除时,致动器30也可以被移除。
另外,虽然可选择地膨胀的致动器30基本上描述为气囊类型的致动器,但是,可选择地膨胀的致动器30可以是构造成从支架20内部膨胀支架20的任何类型的机械致动器。例如,致动器可以是包括横向延伸突起的可横向膨胀装置,所述横向延伸突起构造成接合支架20,以使支架20移动至膨胀构造。在有些实施例中,机械致动器可以使被偏压的可膨胀支架对后退轴向运动比对前行运动具有大体上更大的阻力。
虽然支架20在第一构造描述为大体上圆柱形,但是,在替换实施例中,可以使用足以变为膨胀构造以改变支架周围组织的体积的任何形状。例如,支架可以为三角形、六边形、八角形等。
虽然在此披露的是在膨胀支架之后移除致动器,但是,在替换实施例中,致动器可以保持在支架内部适当位置上,与其附着的轴分开,并保持在椎骨内部的支架中。在有些实施例中,骨填充材料可以插入到在与支架相邻的椎骨内部形成的空隙中。
虽然上述各个实施例是分开描述的,但是,所披露的实施例的特征可以互换地联合。
