We claim: 1. A method of performing an ultrasound ablation procedure on a heart of a patient, comprising: providing a tissue-engaging device; engaging the heart with the tissue-engaging device; positioning the heart into a non-physiological orientation; adjusting the beating of the heart; positioning a portion of an ultrasound ablation device through a mouth of the patient; and performing an ultrasound ablation procedure on the heart. 2. The method of claim 1 wherein the step of adjusting the beating of the heart temporarily slows the beating of the heart. 3. The method of claim 1 wherein the step of adjusting the beating of the heart temporarily stops the beating of the heart. 4. The method of claim 1 wherein the step of adjusting the beating of the heart includes stimulating a nerve. 5. The method of claim 4 further comprising reducing or stopping stimulation of the nerve to allow the heart to beat naturally. 6. The method of claim 4 further comprising the step of stimulating the nerve a subsequent time in order to re-adjust the beating of the heart. 7. The method of claim 4 further comprising the step of stimulating the heart via a pacing device following the completion of stimulating the nerve. 8. The method of claim 4 wherein the nerve is a vagal nerve. 9. The method of claim 4 wherein the nerve is stimulated using an endotracheal, an endoesophageal, an intravascular, a transcutaneous, or an intracutaneous stimulation technique. 10. The method of claim 1 further comprising the step of administering at least one drug during the ablation procedure. 11. The method of claim 10 wherein the drug adjusts the beating of the heart. 12. The method of claim 10 wherein the drug is selected from the group consisting of: a beta-blocker, a cholinergic agent, a cholinesterase inhibitor, a calcium channel blocker, a sodium channel blocker, a potassium channel agent, adenosine, an adenosine receptor agonist, an adenosine deaminase inhibitor, dipyridamole, a monoamine oxidase inhibitor, digoxin, digitalis, lignocaine, a bradykinin agent, a serotoninergic agonist, an antiarrythmic agent, a cardiac glycoside, a local anesthetic, atropine, a calcium solution, an agent that promotes heart rate, an agent that promotes heart contractions, dopamine, a catecholamine, an inotrope glucagon, a hormone, forskolin, epinephrine, norepinephrine, thyroid hormone, a phosphodiesterase inhibitor, prostacyclin, prostaglandin and a methylxanthine. 13. The method of claim 1 further comprising the step of positioning the heart a subsequent time into a different non-physiological orientation. 14. The method of claim 1 further comprising the step of delivering one or more fluids during the ablation procedure. 15. The method of claim 14 wherein the one or more fluids comprises at least one diagnostic agent, therapeutic agent or biological agent. 16. The method of claim 1 wherein a portion of the ultrasound ablation device is positioned within a trachea of the patient. 17. The method of claim 1 wherein a portion of the ultrasound ablation device is positioned within a bronchi of the patient. 18. The method of claim 1 wherein a portion of the ultrasound ablation device is positioned within an esophagus of the patient. 19. A system of ablating a heart of a patient comprising: a tissue engaging device configured to engage the heart and position the heart in a desired orientation to a desired location in a body cavity of the a patient; a stimulator configured to deliver stimulating energy to the heart, altering a heart rate of the heart upon receipt of the stimulating energy; an ablation device configured to generate the ablation energy a predetermined distance from ablation device, configured to be introduced to the location of the body cavity through a mouth of the patient and configured to focus the ablation energy at the predetermined distance to adequately deliver the ablation energy from the location in the body cavity to the heart; and a controller, operatively coupled to the ablation device and to the stimulator, the controller being configured to synchronize delivery of the stimulating energy to the heart via the stimulator and the ablation energy to the heart via the ablation device. 20. The system of claim 19 wherein a distal end of the ablation device is sized and shaped to be positioned within the body cavity connected to the mouth of the patient. 21. The system of claim 20 wherein the body cavity is an esophagus cavity. 22. The system of claim 20 wherein the body cavity is a thoracic cavity. 23. The system of claim 20 wherein the body cavity is a trachea or bronchi cavity. 24. The system of claim 19 wherein the tissue-engaging device is a suction device. 25. The system of claim 19 wherein the stimulator is a nerve stimulation device. 26. The system of claim 19 wherein the stimulator is a drug delivery device.
