Classification: CPC A | IPC A

Claim 0:
1. A catheter alignment system, comprising:
a catheter configured to be inserted into a body part of a living subject, and including catheter electrodes configured to contact tissue at respective locations within the body part;
a display; and
processing circuitry configured to:
receive signals provided by the catheter;
assess respective levels of contact of ones of the catheter electrodes with the tissue in the body part responsively to the received signals, the respective levels of contact being based on a threshold impedance indicative of an electrode being in contact with tissue;
calculate an electrode contact level center of mass based on position coordinates of the ones of the catheter electrodes that meet the threshold impedance;
find a direction in which the catheter should be moved based on the electrode contact level center of mass to improve at least one of the respective levels of contact of at least one of the catheter electrodes; and
render to the display:
a representation of the catheter responsively to the received signals; and
a direction indicator indicating (1) the direction in which the catheter should be moved responsively to the found direction and (2) reference to the electrode contact level center of mass.
