Abstract
Ablation and diagnostic tools having a wrapped flexible circuit are provided. The wrapped flexible circuit can include one or more electrodes on a surface layer, one or more conductive traces on one or more lower layers, and an electrically insulating substrate. The surface layer can be patterned to have multiple electrodes. The lower layer(s) can include electrode contact trace(s) and/or traces for forming thermocouple junctions. The wrapped flexible circuit can be affixed to an outer surface of a metallic tube. The electrodes can be electrically isolated from the metallic tube. The metallic tube can have a sharp end to puncture tissue during ablation or intravascular diagnostic procedure. Additionally, or alternatively, the wrapped flexible circuit can have a pointed end and sufficient structural integrity to puncture tissue during ablation or intravascular diagnostic procedure without the support of a metallic tube.
