可装入3-French导管中的磁性传感器

微型传感器小至0.6mm,可嵌入到导管远侧的尖端中。

一家为微创手术开发三维导向设备的公司宣称,他们已成功地将该公司日前研发出的最小1.3mm传感器缩小至0.6mm。这将使最小达3-French的导管能够在传感器引导下到达体内目标区域。

Ascension Technology公司(美国佛蒙特州,Burlington; www.ascension-tech.com)的MicroBird传感器系列产品可以装入注射针、探针和导管的工作管腔内。这些微小传感器可以嵌入到导管远侧的尖端中,而且不受血管内超声阵列的影响。该公司与研究人员及器械制造商密切合作,共同开发用于支架伸展、给药和血管成像导管的三维导向技术。

传感器采用了直流磁场感应技术,极大减低了金属失真的发生率。一类CF型设备克服了视线跟踪设备外形庞大、容易堵塞的缺点。

该公司日前还宣布,他们已将其产品与Cedara Software公司的成像软件整合,构建了一个医疗成像平台。研究人员和公司可以利用MicroBird设备与导航软件的组合,开发新的介入性手术程序。
