Abstract

A catheter assembly is configured for preventing the occurrence of at least one hotspot during operation of the catheter assembly. The catheter assembly includes a shaft and an end effector. The shaft is designed to be guided into a lumen through a delivery sheath. The electrode is printed on a substrate and is configured to deliver energy to an ablation site. The bottom surface of the electrode is coupled to the substrate and the arcuate element(s) are coupled to the upper surface of the electrode. The arcuate element(s) have a curved upper surface and extend over respective location(s). The arcuate element(s) reduce the intensity of the electrical field at their respective locations to below the arcing level when the electrode is operated in the blood, thereby preventing the occurrence of hotspots during operation.
