技术领域
本公开整体涉及用于通过将干预治疗装置放置在脉管系统内来治疗脉管系统中的缺陷的外科工具。更具体地,其涉及用于从导管的远侧端部释放治疗性治疗装置的装置。
背景技术
血管内治疗装置诸如栓塞线圈、支架、塞等通常通过使用导管放置在脉管系统内。例如,栓塞线圈可放置在破裂动脉瘤内,以在动脉瘤内形成栓塞,并且阻塞血液流入动脉瘤中。此类血管内治疗装置通过导管的管腔被推到治疗位置,并且被部署到待治疗的区域中。
将引导导管或递送导管系统插入期望的治疗部位是用于现代形式的血管内治疗的第一步骤,并且是用于治疗神经血管中的缺陷的最重要步骤之一。尤其是治疗部位周围的脉管系统的大小常常使得治疗装置的准确放置和可靠的分离变得困难。希望最大化放置工具的远侧端部的柔性和分离治疗装置的可靠性这两者。
发明内容
在一个示例中,血管内外科工具包括柔性的导电芯线、回路导体、附接到芯线的远侧端部的电阻加热元件以及通过线圈连接构件附接到电阻加热元件的环的治疗性有效载荷。芯线在其远侧端部处可包括至少一个区段,该至少一个区段从基本上均匀的近侧横截面过渡到较小的远侧横截面。回路导体与芯线电绝缘并粘结到芯线。电阻加热元件可包括电连接到芯线的第一端子、电连接到回路导体的第二端子、螺旋线圈和环。螺旋线圈和环在第一端子与第二端子之间电串联。线圈连接构件可具有低于环的熔融温度的释放温度。

具体实施方式
外科装置包括柔性递送构件、绝缘回路导体和电连接到两者并且被定位在递送管的端部处的加热元件。现在参考附图,其中相同的附图标记表示相同的部分,将详细地公开计算装置和方法的各种示例。
递送构件
图1是血管内分离系统100的一个示例的图示。待递送的治疗装置102借助柔性递送管(未示出)或柔性芯线104通过导管被推动到适当位置中。在图1中,治疗装置102是栓塞线圈,但是其他治疗装置可通过相同或类似的方式进行递送。递送管和/或芯线104通常可具有圆柱形横截面。递送管和/或芯线可由任何生物相容的导电材料制成。递送管或芯线104可以是单件构造,或者可具有由一种材料(诸如不锈钢)组成的近侧端部106和连接到近侧端部106并由不同材料(诸如镍钛诺)制成的远侧端部108。递送构件在其整个近侧端部106更具刚度,并且朝向管的远侧端部108是柔性的。柔性递送构件的远侧端部可包括特殊特征结构以增强其柔性。在一个示例中,芯线104的远侧端部108可以是渐缩的,以降低其刚度并增强其柔性。在另一个示例中,芯线104的远侧端部可具有多个锥形部。在另一个示例中,递送管的远侧端部可包括垂直于递送管的轴线的一系列局部横向狭槽408或狭槽,以降低其刚度并增强其柔性。
具有渐缩的远侧端部的芯线
在图1所示的该示例中,通过减小远侧端部108的至少一部分的横截面来实现芯线104的远侧端部的柔性。在一些示例中,芯线104可从一个横截面到另一横截面112渐缩114。在其他示例中,横截面之间的过渡可以是突然的或阶梯状的,而不是渐缩的。为了方便而非限制,本公开的其余部分将提到渐缩的过渡。锥形部的长度和数量将确定远侧节段的柔性。
绝缘回路导体116附接到芯线104的外表面。在一些示例中,回路导体116的绝缘体118可粘结到芯线104。芯线104和回路导体116一起向在芯线104的远侧端部108处连接的电加热器120供应电力。加热器120允许治疗装置102的分离。
可采用多个示例来控制芯线104的远侧端部的柔性。在一个示例中,芯线104可渐缩114到减小的横截面112,并且然后在加热器附接之前继续该减小的横截面至某一长度。在另一个示例中,芯线104可渐缩到减小的横截面,其中加热器直接附接在锥形部的端部处。在图2所示的另一个示例中,芯线202可具有两个或更多个锥形部204、208,从而导致逐渐较小的横截面206、210和对应地增加的柔性。
在图3所示的另一个示例中,芯线302可具有在不太柔性的节段之间交替的一个或多个柔性节段。例如,芯线302的横截面可向下渐缩304至减小的横截面306,然后向上渐缩回308至较大的横截面310,从而产生功能上类似于接头的离散的柔性节段。可重复该技术以产生芯线的远侧端部,该远侧端部具有如同它们被铰接的那样作用的区段。
具有开槽的远侧端部的递送管
在图4所示的该示例中,递送构件是导电递送管402。单独的绝缘回路导体404在递送管402的管腔内部通过。
在该示例中,通过以间断的构造将横向切口或狭槽408添加到递送管402的壁来实现递送管的远侧端部406的柔性。为了保持导电性,单个狭槽408均不完全穿透递送管402的外周边。
切口以间断的构造放置以保持柔性远侧端部406的完整性。如图5A和图5B所示,每个狭槽408起始于递送管402的圆周504上的原点502处,并且朝向递送管402的轴线506向内前进。在一些示例中,狭槽408可越过递送管的中心轴线506。狭槽可以是平面的或曲线的。平面切口508、510可垂直于递送管的中心轴线或者与中心轴线成锐角或钝角。例如可通过垂直地横向于递送管402的轴线506的带锯、激光器或狭槽切割器形成平面切口。如本领域的技术人员所理解的那样,也可使用其他技术。
原点502的径向位置在不同的各个切口之间可不同。例如,第一切口508可起始于0°的径向位置处502,之后是起始于90°的径向位置处512的附加切口510。附加的切口可跟随其后起始于180°、270°处等,从而形成螺旋成形的切口。也可在狭槽之间使用其他径向间距。
图6A和图6B分别示出了在厚壁和薄壁递送管402中形成的曲线狭槽608、610。曲线切口608、610可垂直于递送管402的中心轴线506,或者相对于递送管402的轴线506以锐角或钝角形成。可例如使用旋转的切割轮或狭槽切割器形成曲线切口,旋转的切割轮或狭槽切割器从狭槽的原点602、612朝向递送管402的轴线506插入递送管402中。如本领域的技术人员所理解的那样,也可使用其他技术。
原点的径向位置在不同的各个切口之间可不同。例如,第一切口608可起始于0°的径向位置602处,之后是起始于90°的径向位置612处的附加切口610。附加的切口可跟随其后起始于180°、270°处等,从而形成螺旋成形的切口。也可在狭槽之间使用其他径向间距。
如本领域的技术人员所理解的那样,可采用径向原点位置的其他组合以实现用于特定应用的特定柔性轮廓。例如,狭槽408可仅在递送管402的相对侧(例如0°和180°)上交替,这仅增强在相对于递送管402的轴线506的一个平面中的柔性。
沿递送管402的轴线的狭槽408的数量和狭槽408之间的间距也影响管的刚度。例如,狭槽408可彼此接近地形成,以最大化切口区段的柔性。狭槽408的间距可以是一致的或可变的以实现不同的效果。在一个示例中,狭槽408的间距可从近侧位置到远侧端部406线性地减小。这导致沿递送管轴线朝向远侧端部延伸的逐渐降低的刚度(增加的柔性)。在另一个示例中,狭槽可在紧密间距与较宽间距之间交替,分别产生更大柔性和更小柔性的不同区域。
分离机构
在几个步骤中,加热器120(电阻元件)由传导线702形成,如图7A至图7C所示。首先,在图7A中,线702形成为螺旋缠绕的线圈704,线圈704具有用作第一端子的平齐切割的近侧端部706和在远侧端部714处的线的直线节段708。在图7B中,直线节段708弯曲,从而在加热器的远侧端部714处形成环712,剩余的线716穿过线圈704的中心返回。在图7C中,绝缘套筒718被放置在剩余的线716之上,以防止线端部的直线节段708与线圈704的内径之间的电接触(短路)。在一些示例中,绝缘套筒718还可将加热元件机械地连接到芯线104或递送管402。然后,剩余的线716用作第二端子。因此,在其最终形式中,加热器120具有全部电串联的第一终端706、螺旋线圈704、环712和第二终端716。
如本领域技术人员将理解的那样,加热器的第一端子706和第二端子716通过焊接、压接、导电环氧树脂或其他导电方式电连接到芯线104/递送管402和回路导体116、404。在一些示例中,加热器的第一端子706可连接到芯线104/递送管402,并且第二端子716可连接到回路导体116、404。在其他示例中,加热器的第一端子706可连接到回路导体116、404,并且第二端子716可连接到芯线104/递送管402。在任一个示例中,电流现在均可流过由芯线104/递送管402、加热器120和回路导体116、404形成的路径。加热器120通过放置在接头之上的可热收缩绝缘/耦接套筒122、410固定到芯线104/递送管402。
待递送的治疗装置102通过线圈连接构件124附接到加热器120的环712。连接构件124是热敏感的,并且当加热器120将其加热到特定温度时释放治疗装置。在一些示例中,连接构件124具有低于加热器120的线的熔点。在这些示例中,加热器120使连接构件124熔融,从而释放治疗装置102。在一些示例中,例如,连接构件可由具有相对低的熔融温度的聚合物制成。其他温度敏感材料可包括形状记忆合金、双金属结构等,它们在加热时改变形状以释放治疗装置。
栓塞线圈
在一个示例中,治疗装置102可以是以线圈132的形状形成的栓塞部件130。线圈132包括通过其中心的缝合丝线134(或一串丝线)。(一根或多根)缝合线134的(一个或多个)远侧端部136附接到线圈132的远侧端部,从而形成远侧接线138。(一根或多根)缝合线134的(一个或多个)近侧端部140在线圈近侧接合点142处固定到线圈。(一根或多根)缝合线134的目的是向线圈132提供抗拉伸性。独立于(一根或多根)抗拉伸缝合线134的线圈连接构件124穿过在加热元件120的远侧端部714处形成的环712,并且线圈连接构件124的两个端部均固定在线圈近侧接合点142处。因此,可通过使电流通过加热器120来部署栓塞部件130。热使得线圈连接构件124例如通过熔融来释放栓塞部件130。
也可经由在本公开中描述的分离系统来部署其他治疗装置。示例包括但不限于:塞、过滤器、血管闭塞装置、支架和动脉瘤囊内装置。
