Abstract: A modular catheter system includes a guiding sheath and multiple catheter inserts configured to couple to the guiding sheath. The guiding sheath can include a navigation sensor coupled to a distal portion of the guiding sheath shaft. A location of a distal portion of a respective catheter insert can be determined based on electrical signals from the navigation sensor. The catheter insert can be electrically coupled to the guiding sheath to provide electrical connection to an electrode assembly on the distal portion of the respective catheter insert. The guiding sheath may include a deflection mechanism that deflects the distal portion of the guiding sheath and a distal portion of a catheter shaft of the catheter insert. The modular catheter system may be configured to be tracked and moved without the catheter inserts requiring a navigation sensor or a deflection mechanism.

Abstract: A catheter is responsive to external and internal magnetic field generators for generating signals representing position and pressure data, with a reduced number of sensing coil leads for minimizing lead breakage and failure. The catheter includes a flexible joint with pressure sensing and position coils, at least pair of a pressure sensing coil and a position coil are serially connected. Methods of calibrating a catheter for position and pressure sensing, and detecting magnetic field interference with one catheter by another catheter or other metal or ferrous object advantageously use signals between two sets of sensors as a “back up” or “error check”.
