摘要:
A medical probe device comprises a catheter (48) having a stylet guide housing (50) with one or more stylet ports (140) in a side wall thereof and a stylet guide (16) for directing a flexible stylet (17) outward through the stylet port and through intervening tissue at a preselected adjustable angle to a target tissue. The total cather assembly includes a stylet guide lumen (61) communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer (60), the electrical conductor being a radiofrequency electrode.
摘要(中):
医疗探针装置包括导管(48),其具有在其侧壁中具有一个或多个通孔(140)的探针引导壳体(50)和用于将柔性探针(17)向外引导通过 管心针端口,并通过与目标组织预选的可调角度的介入组织。 总牵引器组件包括与通心针端口连通的探针引导腔(61)和定位在所述探针引导腔中的探针,用于从端口到介入组织到目标组织的纵向移动。 探针可以是封闭在非导电层(60)内的电导体,电导体是射频电极。
