Abstract

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.
