Abstract
A medical probe, including a flexible insertion tube having a distal end for insertion into a body cavity, and a channel contained within the insertion tube and configured to convey a fluid to the distal end. A terminal member is fixed to the distal end of the insertion tube and includes a distal tip configured to be brought into contact with tissue in the body cavity, the distal tip having a first diameter, and a protruding shoulder surrounding the distal tip and having a second diameter, which is greater than the first diameter. The distal tip has one or more spray ports passing through the shoulder which are coupled to the channel so as to direct the fluid from the shoulder toward the tissue so as to irrigate the tissue.
