技术领域
本公开内容一般地涉及医疗装置,并且更具体地,涉及集成的导管和脉冲发生器系统和方法。
背景
心脏是人循环系统的中心。它包括执行两种主要的泵送功能的电机械系统。心脏的左边部分从肺汲取氧合血,并且将其泵送到身体器官,为所述器官提供它们对氧的代谢需要。心脏的右边部分从身体器官汲取去氧合血,并且将其泵入肺中,在肺中所述血液被氧合。心肌(心脏肌肉)收缩产生这种泵送功能。在正常的心脏中,窦房结,即心脏的天然起搏器,产生称为动作电位的电脉冲,其通过电传导系统传播到心脏的各个区域,以使这些区域的心肌组织兴奋。动作电位在正常电传导系统中传播的协同延迟引起心脏的各个部分同步收缩,导致有效的泵送功能。阻断的或否则异常的电传导系统和/或恶化的心肌组织引起心脏的不同步收缩,导致差的血液动力学性能,这包括对心脏和身体其余部分的减少的血液供应。心脏不能泵送足够的血液以满足身体代谢需求的病症称为心力衰竭。
心肌梗死(MI)是由心脏局部缺血引起的心肌组织部分坏死,即其中由于血液供应中断引起的心肌缺乏足够的氧和代谢物去除的病症,所述血液供应中断由血管如冠状动脉的阻塞引起。称为梗塞组织的坏死组织,失去正常、健康的心肌组织的收缩性质。结果,心肌的整体收缩性减弱,导致受损的血液动力学性能。在MI后,梗塞组织区域膨胀,心脏重塑开始,并且发展成整个左心室的尺寸的慢性、整体膨胀和形状改变。后果包括进一步受损的血液动力学性能、显著增加的发展心力衰竭的危险和增加的心脏性猝死的危险。
当血管如冠状动脉部分或完全阻塞时,可以进行血运重建过程诸如经皮腔内冠状动脉血管成形术(PCTA),以重新打开该阻塞的血管。血运重建还通常伴随着将PCTA步骤与向受影响区域递送冠状支架(stent)结合,以保持该动脉不闭合。血运重建的作用可以导致对心脏组织的额外损伤,称为再灌注损伤。当恢复流动(再灌注)时,引发了一些事件,如氧自由基的增加,改变的钙离子(Ca2+)处理,改变的新陈代谢,微血管内皮功能障碍,以及血小板和嗜中性粒细胞活化,其导致再灌注损伤。再灌注损伤可以导致顿抑心肌,无流回现象,和具有肌细胞坏死的致死性再灌注。另外,血运重建过程本身包括冠状动脉的暂时阻塞。另外,由血运重建过程移去和转移的斑可能进入从进行血运重建的血管分支出来的小血管,引起这些小血管的阻塞。在血运重建过程期间移走的斑还可能引起远端栓塞。暂时的阻塞,或斑的移去和转移可以引起心脏损伤,如梗死组织区域的进一步扩大。另外,已知血运重建过程增加发生心律失常的危险。
在血运重建过程中提供起搏可以降低由再灌注损伤引起的损害以及在血运重建过程中心律失常的可能性。需要用于提供这种治疗的改进的系统和方法。
