Abstract:
一种导引器，可包括杆和近端电极。所述杆可以包括近端部分和内部腔，所述内部腔被配置为容纳通过它的导管。所述近端电极可以与近端部分耦合并且可以被配置为用作电源或电宿，从而在内部腔内产生电场。与导管耦合的电极的位置可以根据所述电场来确定。
Abstract(English):

An introducer may comprise a shaft and a proximal electrode. The shaft may have a proximal end portion and an interior lumen, the interior lumen configured to receive a catheter therethrough. The proximal electrode may be coupled with the proximal end portion and may be configured to act as an electrical source or sink so as to create an electrical field within the interior lumen. A position of an electrode coupled with the catheter may be determined according to the electrical field.
