The invention relates to methods of applying energy to various body portions to produce a therapeutic response. According to embodiments, the applied energy is ultrasound and may be delivered by an ultrasound focusing device deployed in the body, for example, by using an endoscope. The energy may be used to effect a variety of therapeutic responses, including ablating lesions in the gall bladder, treating gastrointestinal reflux disease, or treating fecal incontinence.

Methods of delivering energy to body portions to produce a therapeutic response

An optical feeding tube includes an elongated sheath having a first lumen for delivering nutrients to a gastrointestinal tract and an imaging device disposed in a second lumen. The imaging device provides visualization of an area adjacent a distal end of the elongated sheath. The imaging device can be an optical fiber extending from a proximal end to a distal end of the elongated sheath. The optical feeding tube can also include a retention device. The method for placing the feeding tube involves passing the feeding tube through an opening in the abdominal wall and into a gastro-intestinal tract while observing a passageway ahead of the feeding tube.
