Abstract

The present invention describes methods and apparatus for phototherapeutically treating, e.g., ablating, coagulating, and/or phototherapeutically modulating a target tissue, e.g., cardiac tissue. The methods include introducing a flexible elongate member into a predetermined tissue site with the flexible elongate member having a proximal end, a distal end and a longitudinal first lumen extending therebetween. A portion of the distal end of the flexible elongate member contains holes, such that the porous portion is positioned proximate to the tissue site. A solution is injected through the porous portion, thereby diluting body fluid(s) and/or blood about the tissue site. An energy emitter is slidably positioned through the lumen proximate to the tissue site and energy is transmitted through the holes of the distal end of the elongate member through the energy emitter.
