摘要：
Methods and apparatus of embodiments of the invention are adapted to treat tissue inside a patients body. Aspects of the invention can be used in a wide variety of applications, but certain embodiments provide minimally invasive alternatives for treating atrial fibrillation by delivering a tissue-damaging agent to selected areas of the heart. One exemplary embodiment of the invention provides a method of treating cardiac arrhythmia. This method includes positioning a distal tissue-contacting portion of a body in surface contact with a tissue surface of cardiac tissue detecting the surface contact between the tissue-contacting portion and the tissue surface and thereafter, injecting a tissue-ablating agent into the cardiac tissue through the tissue-contacting portion of the body.
