APPARATUS FOR REMODELING/PROFILING A TISSUE LUMEN, PARTICULARLY IN THE URETHRAL LUMEN IN THE PROSTATE GLAND

摘要

Apparatus for tissue lumen (such as urethra) remodeling includes an elongated shaft and at least one expandable structure on a distal end of the shaft. At least one desiccator or energy emitter is carried by the structure and operable to define a support structure in lumen tissue that resists lumen closure. Apparatus is also disclosed for identifying tissue or developing a profile of tissue along the lumen based at least in part on an electrical characteristic of the tissue. Methods of remodeling and profiling are also disclosed.
