Abstract
Official abstract text for this publication.
A system and method is provided that allows for determining the local impedance of one or more electrodes of an electrode catheter. Such local impedance may be utilized to identify the relative position of an electrode catheter to a sheath of a guiding introducer. In another arrangement, local impedance of a catheter electrode can be utilized to calibrate a catheter electrode to provide improved contact sensing.
First claim
Opening claim text (preview).
What is claimed is: 1. A medical system for monitoring the position of a catheter relative to a sheath disposed within a patient's body, the system comprising: one or more body surface electrodes configured for external application to the patient body; a generator configured to generate an electrical signal for receipt by a first electrode of the catheter; a measurement circuit configured to: at a first time, measure a first response between the first electrode and said one o…
