A medical probe device for contacting tissue within the body a catheter tube having a control end and a probe end. The probe end includes a housing having a port. An element is located within the housing that is movable between a first position confined within the housing and a second position extending through the port outside the housing. The element has a distal tip adapted to penetrate a tissue region during movement between the first and second position. The element comprises an electrode for emitting electromagnetic radio frequency energy into the tissue region, or cannula with an interior lumen for conveying fluid to and from the tissue region, or a sensor for sensing temperature conditions in the tissue region.
