医疗电子新增长点:神经植入设备

启蒙19

一家名为NeuroPace的新创公司希望获得自己的首款神经植入设备的销售许可。NeuroPace的工作仅仅是新兴的神经设备领域市场激增的缩影。

    NeuroPace公司于今年七月将一款用于治疗癫痫症的大脑植入设备送交美国食品药品管理局审批,该产品已经经过了十年的研发。NeuroPace公司希望自己的RNS系统能够在一年内获准使用。

    NeuroPace首席医务官Martha Morrell在BioMedDevice论坛上表示:“我相信在未来十年里多种闭环、开环脑部刺激设备将会取代破坏性的手术疗法”。

    癫痫症植入设备的试用让研究人员见识到了这种技术在治疗各种严重病症时的潜力,可行的范围覆盖了从疼痛、抑郁到帕金森和阿尔茨海默病在内的各种病症。

    Morrell说:“这是我们首次深入大脑观察实时变化。我们把它当作病症管理工具”。

    NeuroPace公司的RNS植入设备拥有两块自制芯片,发现癫痫症患者的异常脑部活动比此前预测的更剧烈。

    Morrell表示:“之前没有过针对癫痫症患者的诊断记录,结果表明病症发作仅仅是冰山一角。我们发现这些病患每天最多需要进行600次刺激,每次时长1-2分钟”。

    医生可以对这种设备进行编程,让它对多种状况进行感知和响应。NeuroPace维护着一个数据库,可以用于脑电波活动的长期研究。

    Morrell表示这类设备的潜力在于可以向大脑上的目标区域释放微量药品、进行电流刺激。新的电极整列和传感器能够扩展此类设备的适用症状。除了脑电波以外,研究人员还在研究大脑血流、氧气、神经递质乃至温度的变化,以此来分析病症
