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”.

Claim (Index 16):
A catheter for use with a catheterization system having a plurality of external magnetic field generators, each generating a position-data magnetic field, the catheter comprising:\n a flexible tubing; and a distal section configured for engagement with patient tissue, the distal section having a proximal portion and a distal portion, and comprising:\n an internal magnetic field generator positioned in one of the proximal or distal portions, the internal magnetic field generator generating a pressure-data magnetic field; \n a first plurality of pressure sensing coils and a second plurality of position sensing coils positioned in the other of the proximal and distal portions,\n the first plurality of pressure sensing coils configured to sense the pressure-data magnetic field and generate signals representative of data relating to pressure exerted on the distal section when engaged with tissue, each of the pressure sensing coils of the first plurality being generally parallel with a longitudinal axis of the catheter; \n the second plurality of position sensing elements configured to sense each of the position-data magnetic fields and generate signals representative of data relating to a position of the distal section; and \n \n a first lead serially connecting at least one pair of one of the first plurality of pressure sensing elements and one of the second plurality of position sensing elements.
