Abstract
High-density mapping catheters with an array of mapping electrodes are disclosed. These catheters can be used for diagnosing and treating cardiac arrhythmias, for example. The catheters are adapted to contact tissue and comprise a flexible framework including the electrode array. The array of electrodes may be formed from a plurality of columns of longitudinally-aligned and rows of laterally-aligned electrodes.
Claims10
A basket catheter comprising:
- an elongated catheter shaft including a proximal end and a distal end;
- a flexible basket catheter, including a plurality of splines, coupled to the distal end of the catheter shaft and configured to conform to tissue when extended into a deployed configuration;
- a plurality of electrodes mounted to the splines, the plurality of electrodes organized into triangular-shaped cliques along each of the splines;
- and
- wherein each of the plurality of splines include a plurality of pads that extend transverse to a length of the splines and are configured to host one or more of the plurality of electrodes, the pads on adjacent splines are longitudinally offset to facilitate interleaving of the pads when the flexible basket catheter is actuated into a contracted configuration.
