| 摘要 |
The present invention is drawn to methods for ablating tissue within an organ, e.g., a heart, using a catheter. The catheter includes a tubular catheter having a proximal end, a distal end and a lumen therebetween, a plurality of independent flexible guide members, and an energy emitter. The method includes introducing the catheter into an organ, e.g., a heart, and performing ablation of tissue, e.g. diseased tissue. The energy emitter is slidably positioned within one or more of the flexible guide members so that the energy emitter is located proximate to the tissue site. Energy is emitted through the emitter, thereby treating, e.g., phototherapeutically, e.g., ablating, the tissue with minimal or no harm to the surrounding healthy tissue. A method may be used for therapeutic or prophylactic treatment of tissue. |
