Abstract
Aspects of the present disclosure are directed to the localization of an introducer sheath relative to an intravascular catheter. Further embodiments of the present disclosure are directed to the visualization of the introducer sheath on a graphical user interface of a navigation system.
Claims15
A system for visualizing an introducer sheath location within the body, the system comprising:
- controller circuitry configured and arranged to
- receive electrical signals from one or more electrodes on an electrophysiology catheter indicative of a position and orientation of a distal end of the catheter and a position of an introducer sheath relative to the catheter,
- determine the position and orientation of the distal end of the catheter and the position of the introducer sheath relative to the catheter, and
- generate an image for a display that visualizes states indicative of the relative locations of the catheter and the introducer sheath including a first visualization state where the visual indicator of the introducer sheath is proximal a proximal-most electrode of the plurality of electrodes, a second visualization state where the visual indicator of the introducer sheath is disposed over at least one of the plurality of electrodes of the catheter, and a third visualization state where the visual indicator covers each of the one or more electrodes on the catheter.

A system for detecting and visualizing a location of an introducer sheath comprising:
- an introducer sheath configured and arranged to navigate a patient vasculature;
- a catheter including one or more electrodes, the catheter configured and arranged to be delivered to a target region within the vasculature via a lumen within the introducer sheath;
- controller circuitry communicatively coupled to the one or more electrodes and configured and arranged to
- determine a position of the catheter within the patient based on electrical signals received from the one or more electrodes on the catheter,
- determine an approximate position of the introducer sheath based on the electrical signals received from the one or more electrodes on the catheter, and
- generate an image for a display that visualizes the relative locations of the catheter and the introducer sheath;
- and
- the display, communicatively coupled to the controller circuitry, is configured and arranged to display the generated image to a clinician to assist in diagnostic and therapeutic intravascular procedures.
