A description is given of a probe for making strip-shaped transmural lesions in one or more walls of the atria of the heart in open-heart surgery. The stripe-shaped lesion blocks electrical impulses in a direction crosswise to the lesion. The probe has a handle ( 1 ), a closed end ( 2 ) and a relatively rigid shaft ( 5 ), and means ( 6, 7 ) for coupling the probe to an RF power source. |
