导管末端定位方法

[0001] 相关申请的交叉引用:本申请要求2009年6月12日递交的美国临时专利申请序号No. 61/213,474的优先权,该美国临时专利申请的全部公开内容通过引入被并入本文。

技术领域

[0002] 本发明涉及一种血管内设备定位。具体地讲,本发明涉及一种用于使用心电图(ECG)信号将诸如中心静脉导管的血管内设备的末端定位在心脏的内部及周围的方法。

背景技术

[0003] 心脏的导电系统创建特定的电信号,这些电信号的电能分布和行为指示胸腔内的特定位置和/或特定心脏机能或症状。当在血管内测量时,即,从血管内或者从心脏内测 量时,心脏的电活动的某些参数可以用于识别心血管系统中的特定位置和/或正常或异常的机能症状。而且,通过局部地且精确地识别症状的位置和类型,可以优化这样的症状的治疗,并且可以实时地监控治疗效果。

[0004] 通常解决了两种类型的临床应用。第一种涉及引导血管内设备穿过心血管系统,而第二种涉及心脏的电活动的无创或微创远程监控。

[0005] 血管内导管的引导、定位和放置确认在许多临床应用中是有必要的,所述临床应用例如:

[0006] I、中心静脉进入,比如,CVC、PICC、可植入端口 ;

[0007] 2、血液透析导管;

[0008] 3、起搏器引线的放置;

[0009] 4、血液动力学监控导管,比如,Swan-Ganz和中心压力监控导管;以及

[0010] 5、将导丝和导管引导到左心中。

[0011] 导管末端的位置对于患者的安全、手术的持续时间和手术的成功是非常重要的。如今的用于确认导管末端的目标位置的金标准是胸部X射线。另外,目前市场上可以买到设法克服胸部X射线确认的限制的两种类型的实时引导产品:电磁的和基于ECG的。在使用实时引导的医院中,就减少X射线的数量、手术时间和手术成本而言,结果有所改进。在实时引导下,首次成功率通常从75% -80%提高到90% -95%。另外,在比如意大利、比利时、德国的使用ECG引导的医院中,对于超过90%的患者已经省去了胸部X射线确认。美国主要使用电磁系统,而欧洲主要使用基于ECG的系统。在就技术采用而言确定美国市场与欧洲市场之间的差异的其他因素之中:a)被允许执行手术的医护人员的类型:在美国,护士具有更大的灵活性山)所放置的设备的类型:在美国越来越频繁地放置PICC ;c)价格敏感性:欧洲市场似乎对价格更敏感;以及d)特定制造商将目前的引导设备商业化为仅与他们的导管一起工作:引导系统的市场渗透率反映了导管制造商的市场渗透率。

[0012] 还发现,关于目标末端位置应该所处的地方存在不同的意见:例如,SVC的下三分之一处或RA。因此,引导技术应该顾及区分这些位置。作为目前的金标准的胸部X射线不总是顾及这样的区分,这样的区分要求通常好于2cm的精度。此外,由于基于ECG的系统使用与心脏活动相关的生理信息,所以它们引导放置的能力对于解剖来说是精确的。就测量脉管系统中的导管末端与通常放置在患者胸部上的外部参考之间的距离的电磁引导系统而言,情况不是这样。由于这个方面,基于ECG的系统可以用于记载导管放置的最终结果,这可能取代胸部X射线作为金标准。

[0013] 可利用的最有价值的诊断工具之一,ECG将心脏的电活动记录为波形。通过解释这些波形,可以识别节律紊乱、传导异常和电介质失衡。ECG辅助诊断和监控诸如急性冠脉综合征和心包炎这样的症状。心脏的电活动生成辐射穿过周围组织到达皮肤的电流。当电极附接到皮肤时,它们感测这些电流,并且将它们发送到心电图仪。由于来自心脏的电流在许多方向上辐射到皮肤,所以电极被放置在皮肤上的不同位置处,以获得心脏的电活动的总状况(total picture)。电极然后与心电图仪设备或计算机连接,并且记录来自不同测试方法(perspective)的信息,所述不同测试方法被称为导联(lead)和平面。导联提供在两个点或极之间的心脏电活动的视图。平面是提供心脏的电活动的不同视图的心脏截面图。目前,ECG波形的解释基于识别波形分量幅值、分析这些幅值、然后将这些幅值与某些标准进行比较。这些幅值分量的改变指示某些症状(比如,ST段升高)或者指示心脏中的某些位置(比如,P波的幅值)。在如今的实践中,ECG监控器广泛用于记录ECG波形。越来越 平常的应用可供用于ECG幅值分量的自动识别。在某些情况下,可利用用于决策制定支持和用于对于基本心脏病的ECG幅值分量的自动解释的工具。

[0014] 远程患者监控是完善的医学领域。但是,心脏病的远程监控没有如它预期所需要的和可能的那样被广泛接受。原因之一涉及获取与心脏活动相关的信号(具体地,ECG信号)的方式相对复杂。目前远程监控技术的另一个重要限制因素是使用在患者端和医生端这二者都难以通过接口连接的通信信道,比如,电话线。

[0037] 本发明的实施方案有利地提供用于在许多临床应用和设置中获得并使用血管内ECG的具有创造性的仪器(一个或多个)、基于计算机的数据处理算法和方法。例如,设备可以用于将血管内设备引导到心脏的内部及周围,比如,在上腔静脉、右心房和右心室中引导中心静脉进入设备。这样的中心静脉进入设备可以包括中心静脉导管(CVC)、外周置入中心导管(PICC)、可植入端口、血液透析导管、隧道式导管和其他设备。可以从利用具有创造性的仪器进行引导受益的其他设备是遍布中心静脉系统放置的临时起搏器引线。通过减小将这些设备引导到适当位置所需的对比度和辐射的量,左心手术中所使用的导管和导丝也可以从本发明受益。在另一个实施例中,所述仪器可以用于微创监控心脏病和基于其电活动来评估心脏病,比如,评估心搏周期中的前负荷,或者监控充血性心力衰竭中的ST段和T波。 [0038] 在本发明的一方面,描述由无菌适配器、用于信号获取的电子模块、计算机模块、软件以及外围设备和连接构成的仪器。在一个实施方案中,用于信号获取的电子模块可以专用于获取并处理由身体产生的血管内电信号(血管内ECG),在另一个实施方案中,电子模块可以专用于获取并处理血管内ECG以及皮肤ECG。

[0039] 在一个实施方案中,电子模块和计算机模块可以是分离的模块,在另一个实施方案中,它们可以集成在同一模块和外壳中,然而,在另一个实施方案中,它们可以通过诸如蓝牙的无线连接彼此通信。在一个实施方案中,所述仪器可以包含集成的打印机,而在另一个实施方案中,打印机可以是在外部,并且附接到所述仪器,所述仪器通过比如无线的网络与其他设备连接。在又一个实施方案中,所述仪器可以用于遥测和用于将血管内心电图发送到远程位置,比如,通过电话线、互联网和/或无线电话。以上提及的实施方案的任何组合也是可以的。

[0040] 在本发明的另一方面,各种构造使得可将诸如中心静脉进入设备的血管内设备与用于信号获取和处理的电子模块连接。在一个实施方案中,所述设备由具有两个端部的连接线和在每个端部的特定连接器构成。在一个端部,所述线可以与通常可以在市场上买到的金属或镍钛诺导丝或者探针连接。在另一个端部,所述线可以与电子模块安全地连接。在另一个实施方案中,所述设备包括比如由镍钛诺或不锈钢制成的、具有无覆层的远侧端和近侧端以及厘米标记(cm marking)的覆层导丝。在这样的实施方案中,在连接线与覆层导丝的近侧端连接时,覆层导丝被血管内地插入。在另一个实施方案中,所述设备包括设有电连接线的导管-注射器适配器。在一个端部,电连接线与流体接触,所述流体比如是在导管-注射器适配器内流动的盐水。在另一个端部,连接线可以与电子模块连接。

[0050] 图2A、图2B和图2C描绘各种血管内适配器设备。

[0051] 图2A图示说明可以由隔离导电线(255)制成的、具有两个端部的适配器:一个端部与血管进入设备连接(255),另一个端部与电子模块连接(250),隔离导电线由铜或不锈钢制成。与血管进入设备连接的端部包括可以具有几种构造的连接器。在一个实施方案中,该连接器是具有弹簧的J夹连接器(230),所述弹簧在J末端不延伸时用于隔离目的。在另一个实施方案中,连接器是隔离鳄鱼夹(220)。在另一个实施方案中,连接器是导管-注射器适配器(210)。导管-注射器适配器的一个端部(211)可以与导管鲁尔接头(Iuer)连接。另一个端部(215)可以与注射器连接。金属嵌件(214),比如,金属环,位于适配器的本体内部,当盐溶液从注射器朝向导管内腔流动时,与盐溶液接触。金属嵌件通过适配器壁与线(212)连接,线(212)又与连接器(250)连接。在一个实施方案中,连接器(250)通过外部隔离件(241)固定,并且插入电子模块中的安全插头。在另一个实施方案中,连接器(250)具有顾及标准ECG线缆连接器的容易的且安全的连接的优化乳头式形状(242)。

[0081] 图标(920)是心脏的表征,位置A至E(930)图示说明心脏和血管系统中的不同位置,这些位置可以通过分析血管内ECG来进行区分。当脉管系统中的位置通过算法识别时,图标(930)上的对应地方和字母变得高亮,或者以某种其他方式使得图标(930)上的对应地方和字母对于使用者是可见的。条(940)、(950)和(960)示出信号能量水平。“E”条(940)描绘从血管内设备的末端的当前位置处的ECG频谱计算的电能的量。“R”条(950)示 出从参考位置处的ECG频谱计算的电能的量。“M”条(960)示出从使用来自皮肤电极的监控ECG信号的ECG频谱计算的电能的量。按钮“打印”(960)使得使用者可在打印机上(例如,在标签打印机上)打印记载病例的信息,以快速地贴附到患者的病例表。

[0082] 图IOA和图IOB描绘根据本发明的实施方案的图形使用者界面所显示的信息的示例性打印输出。

[0083] 图IOA图示说明将导管末端放置在SVC的下三分之一处的手术的情况的打印输出(1000)。区域1010描绘心脏图标,由此对应于上腔静脉(SVC)的下三分之一的字母“B”高亮(1040)。区域1030描绘在窦房结附近的腔静脉-心房接点的导管末端处记录的参考ECG波形。区域1020描绘在手术结束时其被放置的位置上的导管末端处的ECG波形。关于图10A,该位置是SVC的下三分之一,并且ECG波形对应于该位置。患者姓名(1001)和手术日期(1002)也被打印。

[0084] 图IOB描绘类似的打印输出(1050),除了手术结束时的最终位置是在心脏图标(1060)上的位置C(1090)处的腔静脉-心房接点之外。“SA结”区域描绘参考ECG波形(1080),“最终位置”区域(1070)示出导管被放置成末端在窦房结处:最终位置上的ECG波形与窦房结(SA结)处的参考位置上的ECG波形类似或者甚至是相同的。已知的是,SA结的接近度指示腔静脉-心房接点的位置。这些位置有时被一些临床医生认为是相同的。

[0085] 图11是用于使用心电图信号将血管内设备定位在心脏的内部或附近的基于计算机的方法(1100)的框图。

[0086] 所述算法应用于由适配器获取的到达血管内设备(并且可选地,还通过皮肤电极)的输入信号(1102) (ECG)。错误检测块(1105)检测至少三种类型的错误状况/异常,例如,当除纤颤器已应用于患者时,当起搏器激起激励脉冲时,和/或当引线/电极脱离时。这些错误/异常可以被不同地处理,并且使用者可以被告知异常的存在和处理异常的方式(1110)。

[0087] 预处理块(1115)可以放大信号、降低噪声、除去伪像等。在一个实施方案中,将信号重新缩放到显示范围在使用者控制下发生,并且不是自动的,与最近可用的ECG监控器一样。因此,ECG的幅值的改变易于被注意到。高通滤波器校正基线,并且减少诸如呼吸伪像这样的伪像。宽带噪声抑制可以使用选择性滤波器(比如,小波变换)来实现。对其他设备和电网的心电图干扰可以通过以60Hz或50Hz为中心的陷波滤波器(窄带滤波器)来抑制,以适应国内或国际电源。高频噪声可以利用低通滤波器抑制,在一个实施方案中,所述低通滤波器利用可变长度平均来实现,所述可变长度平均例如为与心搏周期对应的运行窗口、几个连续心搏周期期间的ECG的平均,等等。自适应滤波块(1120)通过使误差信号最小来优化滤波器系数。

[0088] 时域模式识别块(1130)识别ECG波形的元素、它们的关系(一个或多个)和它们随时间的行为(一个或多个)。块1130中的时域模式识别算法以及频域模式识别块1140的重要方面是数据历史。对于某些元素,实时分析ECG,而对于其他元素,在电子和/或计算机模块的存储器中维护具有合适缓冲长度的数据缓冲器,以便使得可进行历史数据分析和基于该分析的预测。在一个实施方案中,数据历史缓冲是使得与几次心跳对应的ECG信号可保存在缓冲器中的几秒长。双缓冲技术使得可在第二缓冲器继续储存信号的同时对一个缓冲器中的波形进行处理。因此,在对一个缓冲器中的波形进行处理时没有信号数据丢失。 在一个缓冲器上的数据处理完成之后,结果被发送到决策支持算法(1150),并且两个缓冲器交换角色。缓冲器的长度适应数据处理的持续时间,以便确保没有数据丢失。类似的双缓冲技术也应用到经历频域模式识别块(1140)的数据。

[0089] 在血管内ECG的情况下,感兴趣的元素可以包括,但不限于,以下中的一个或更多个:

[0090] 1、P、Q、R、S、T和U波、它们的峰值、幅值和持续时间;

[0091] 2、P-R、S-T 和 T-P 段 / 间期(interval)的持续时间;

[0092] 3、S-T段的升高;

[0093] 4、P-P和R-R间期的方差;

[0094] 5、S-T的方差和R-T间期的方差等;

[0095] 6、P波的峰间值和QRS复合波的峰间值;

[0096] 7、P波幅值与R波幅值的比率和P波幅值与QRS复合波峰间幅值的比率;

[0097] 8、P波的极性:单正极、单负极或双极性;

[0098] 9、P波、QRS复合波和T波的导数;

[0099] 10、R-R间期和心跳的时间平均值;

[0100] 11、某个时间段期间的P波幅值/峰值的最大值和P波峰间幅值的最大值;

[0101] 12、某个时间段期间的R波幅值/峰值的最大值和QRS复合波峰间幅值的最大值。

[0102] 几种技术可以用于从ECG波形得到以上列出的信息,包括,但不限于,以下中的一个或更多个:

[0103] I、“峰值检测”;

[0104] 2、一阶导数的计算;

[0105] 3、沿着一次心跳中的信号运行平均(running average)和沿着多次心跳运行平均;

[0106] 4、自适应阈值;

[0107] 5、自动相关。[0108] 块(1125)中的快速傅里叶变换对储存在具有某个长度的缓冲器中的一些ECG采样(比如,256、512、1024、2048或更多的数据采样)执行快速傅里叶变换。傅里叶变换将波形从时域变换到频域。

[0109] 频域模式识别块(1140)图示说明在频域中对ECG执行的模式识别的各个方面,包括,但不限于,以下中的一个或更多个:

[0110] I、主分量分析,S卩,频谱的最重要元素的确定(类似于确定心电图的形态元素,t匕如,时域中的某些波和段);

[0111] 2、为了减少基于主分量的计算量的数据压缩;

[0112] 3、主分量的数量和形态的确定,具体地,确定谱是否具有仅一个、两个或多个主频率(频带);

[0113] 4、从频谱计算谱功率和信号能量;

[0114] 5、为了降低宽带噪声沿着单个谱上的频域范围运行平均;

[0115] 6、为了滤除伪像沿着几个谱运行平均;

[0116] 7、谱的另外的形态元素的确定,比如,最大频率、最大频率中所包含的能量、频率直方图(即,什么频率包含多少能量)、最高有效的最大能量峰值的频率等;

[0117] 8、从谱分布确定的主分量和其他参数的随时间的行为和平均值的计算,比如,确定某个时间段期间的信号能量的最大值和谱功率的最大值;

[0118] 9、基于谱分析来确定/估计某些心脏病。该确定/估计也在决策支持块1150和1250中被更详细地执行。

[0119] 几种决策支持算法使用由时域模式识别和频域模式识别算法提供的信息。在一个实施方案中,块(1150)支持将血管内设备放置在SVC的下三分之一处或者腔静脉-心房接点。

[0120] 具体地讲,块1150基于在导管放置期间首次到达腔静脉-心房接点的概念。在腔静脉-心房接点或者在窦房结附近,P波和其他电参数达到最大值。在腔静脉-心房接点,P波是单极性的。在到达腔静脉-心房接点的窦房结(即,P峰幅值和谱功率的最大值)之后,将导管向后拉几厘米,直到P波减小到在腔静脉-心房接点达到的幅值的一半为止。在P波减小到腔静脉-心房接点的幅值的一半的位置处,认为导管在上腔静脉的下三分之一中。P波峰幅值或峰间幅值以及谱功率用于将脉管系统中的位置映射到ECG波形。

[0121] 更具体地讲,在接收到与血管内设备相关联的血管内ECG信号之后,在多个预定时间段期间对该信号进行处理,以计算每个预定时间段内的P波幅值和谱功率。然后从所述多个P波幅值确定最大P波幅值,并且从所述多个谱功率计算相关联的最大谱功率。将这些最大值被确定所在的位置与心脏内部或附近的预定位置(诸如腔静脉-心房接点)相关联。然后在每个预定时间段内基于P波幅值与最大P波幅值的比率和谱功率与最大谱功率的比率来计算血管内设备的位置,然后向使用者显示血管内设备的位置。另外,还可以使用P波的极性和R波幅值来确定血管内设备的位置。

[0122] 单个标准或者这样的标准的组合可以用于支持决策制定。在一个实施方案中,Tl、T2和T3可以是针对每个患者不同的凭经验建立的阈值,并且所述算法可以基于当前测量使用自适应循环来调整阈值。在另一个实施方案中,这些阈值是预定的。

[0123] 在可替换实施方案中,P峰/P幅值或P波峰间幅值与R峰/R幅值或与QRS复合波峰间幅值之间的比率也可以用于建立相对于窦房结的位置。在一个实施方案中,P峰/幅值必须是R峰/幅值的大约一半,并且对于与SVC的下三分之一对应的位置,P波必须是单极性的。在另一个实施方案中,P波峰间必须是QRS峰间幅值的一半,并且对于与SVC的下三分之一对应的位置,P波必须是单极性的。

[0124] 如上所述,可以例如通过将心脏图标上的与被系统识别的ECG的类型对应的合适位置加高亮来向使用者呈现决策支持算法块1150的结果(1160)。

[0125] 图12中描绘的决策支持算法块1250基于将当前位置处的P波、R波和P波谱功率与从等效导联(比如,导联II)中的皮肤心电图确定的这些参数的值进行比较。阈值Tl至T6是经过相对于每个患者的自适应调整的经验值。可以使用图12中所示的每个标准或标准的组合。

[0126] 还可以使用其他决策算法,特别是与从ECG谱计算的电能水平相关的决策算法。 在放置血管内设备的情况下,一个标准可以是,在与SVC的下三分之一对应的位置处,从血 管内ECG计算的平均电能高达从皮肤水平处的血管内ECG或者从对应导联(比如,导联II)中的皮肤ECG计算的平均电能的两倍。

[0127] 图13图示说明心脏的心脏传导系统,而图14图示说明心脏的传导系统中的电信

号传播。

[0128] 这些图示出心脏的传导机制,该传导机制解释了所测量的心脏内的电能分布为何指示心脏内的特定位置。因此,可以测量局部电信号、行为和能量浓度,并且可以更精确地确定心脏和血管内的位置;还可以更精确地描述局部心脏症状。

[0129] 心脏的传导系统起始于心脏的主导起搏器、窦房结(1310)。SA结的固有速率是60至100次心跳/分钟。当脉冲离开SA结时,在它进入房室(AV)结(1320)和心室的途中,它沿着巴赫曼束(Bachmann’ s bundle) (1350)和结间通路行进通过心房。在脉冲穿过AV结之后,它行进到心室,首先行进到希氏束(bundle of His) (1330),然后沿着束支(bundle branch)行进,最后行进到浦肯野纤维(Purkinje fiber) (1340)。由于结合组织(junctional tissue)中的起搏细胞和心室上的浦肯野纤维从SA结接收脉冲,所以它们通常保持休眠。仅当它们不从SA结接收脉冲时,它们发起脉冲。AV接点的固有速率是40至60次心跳/分钟,心室的固有速率是20至40次心跳/分钟。图14中示出了电脉冲的不同传播速度。脉冲从SA结(1410)起以大约0. 5m/s (米/秒)传播通过心房肌(1420)和心室肌(1460),以大约2m/s传播通过束支(1440)和(1450),以大约4m/s传播通过浦肯野纤维(1470),并且以大约0. 05m/s传播通过AV结(1430)。

[0130] 甚至是在心律失常的情况下,即,在通过标准皮肤心电图测量的相干P波不存在时,电信号和电能分布也有利地用于识别窦房结的接近度和右心房电活动。尽管在心律失常的一些情况下,在右心房中产生的随机电信号的相干性不足以传播通过身体到达皮肤,但是电能仍存在于右心房中,并且可以被局部血管内测量检测为不相关的P波,即,被检测为ECG波形的P段中的重要电活动。能量测量也对于脉冲传导中的一些局部异常不是那样敏感:改变的自律性(心律失常)、脉冲的逆行性传导、再进入异常。

[0131] 电信号和电能分布还有利地用于量化心脏机能,比如,与心肌的去极化和伸展(extension)相关的前负荷。

[0132] 电信号和电能分布还有利地用于引导导丝和引导导管通过主动脉进入到左心中。该方法对于简化左心房和冠状动脉的进入以及减少将血管内设备引导到这些位置所需的对比度和辐射的量是有用的。在不同的应用中,具有创造性的仪器还可以用于引导导管(比如,Swan-Ganz)通过右心室进入到肺动脉中。其他血管内设备可以被引导,并且可以被用于测量心血管系统的其他位置上的血管内电活动,该血管内电活动是通过利用本发明中介绍的新型装置测量的电描记图可识别的。

[0133] 图15图示说明由于神经元控制系统而导致的心血管系统中的电活动。几个传导路径与心脏(1530)和血管(1520)活动的控制机制相关:感受器(1510)(比如,压力感受器)通过延髓中枢(1500)将与血管状态和心脏状态相关的信息发送到神经系统。下丘脑(1540)和高级中枢(1550)涉及对从传感器/感受器接收的信息进行处理并对该信息作出反应。继而,它们将脉冲(1560)发送回血管和心脏。通过测量与控制系统相关的电活动,可以获得以前不能获得的关于心脏病的信息。

[0134] 本发明的许多特征和优点从详细的说明书是明显的,因此,所附权利要求意图覆 盖落在本发明的真实精神和范围内的本发明的所有这样的特征和优点。此外,由于许多修改和变化将容易被本领域技术人员想到,所以不期望将本发明限于所示和所述的精确构造和操作,因此,所有合适的修改和等同形式都可以被诉诸为落在本发明的范围内的修改和等同形式。
