PROBLEM TO BE SOLVED: To provide a medical apparatus.SOLUTION: A medical apparatus comprises: a flexible insertion shaft, which is adapted for insertion into the body of a patient; a resilient end section, which is fixed to the distal end of the insertion shaft and is formed so as to have, when unconstrained, an arcuate shape; one or more electrodes, which are disposed at respective locations along the resilient end section; a first lumen, which runs from the insertion shaft through the end section so as to convey an irrigation fluid to exit the end section through the perforations of the electrodes; and a second lumen, which runs through the insertion shaft to a distal opening at the distal end of the insertion shaft, and is configured to permit a guide wire to pass through the second lumen from the proximal end of the insertion shaft to exit distally through the distal opening, while conveying the irrigation fluid from the proximal end through the distal opening together with the guide wire. |
