Abstract:
1. A method of cardiac catheterization for controlling displacement of a catheter tip with respect to a heart of a patient and correcting any undesirable deviation of the catheter tip, comprising the steps of: (a) producing monitoring signals during advancement of the catheter along a blood vessel by providing the catheter (C) with at least one sensor (Sm) adapted to deliver cardiac signals that represent an internal cardiogram of the patient and are modified by any deviation of the catheter tip preventing the advance of the catheter, (b) comparing said monitoring signals with a reference during the advance of the catheter, (c) enabling the advance of the catheter when said monitoring signals correspond to said reference and interrupting the advance of the catheter when said monitoring signals deviate from said reference in order to return the catheter tip to a position enabling its advance.
