摘要:
A catheter may be adapted to map a chamber of the heart. The catheter may include a magnetic and/or ultrasound sensor for navigation. The body of the catheter may be pliable and configured to form a predetermined shape upon exiting a catheter sheath. Upon exiting the catheter sheath, the catheter body may be configured to form one or more loops, and the loops may be non-overlapping loops. In some examples, the non-overlapping loops may be concentric loops. Alternatively, the catheter body may be configured to form one or more splines. The catheter body may include an embedded electrode assembly. The electrodes of the electrode assembly may be may be arranged in one or more rows and configured to detect a wave front. The electrode assembly may also be configured to generate and activation sequence and determine a direction of an activation source. The electrode assembly may also be configured to determine the type of activation source, for example a rotational activation source, a focal activation source, and a single-wide activation source.
