Abstract: The invention comprises a method and apparatus for treatment of a body part. More particularly, a method and apparatus for heat treatment of tissue using a catheter inserted into a body part is described along with means for positioning the catheter and means for positioning a set of electrodes relative to a tissue sample for treatment. Still more particularly, radio frequency energy at about 400 to 500 kilohertz is used to provide heat for the tissue treatment.

Abstract: An obesity treatment system has a first treatment region sized and configured for deployment in a duodenum and a second treatment region sized and configured for deployment in a stomach. The first and second treatment regions are spaced apart a distance sized and configured to permit simultaneous deployment of the first treatment region in the duodenum and deployment of the second treatment region in the stomach. The first and second treatment regions each carry at least one electrode, which can deliver energy to ablate tissue in and the duodenum.

Abstract: A sphincter treatment apparatus has an introducer means including a distal portion means. An expandable device means includes a plurality of arm means. Each arm means of the plurality has a distal section means and a proximal section means. Each of distal sections means of the arm means are coupled and each of the proximal sections means of the arm means are coupled to the introducer means distal portion means. The expandable device means is configured to at least partially dilate a sphincter in a deployed state. An energy delivery device means is introduceable from the introducer means into a selected site of the sphincter. The energy delivery device means is configured to deliver sufficient energy to reduce a frequency of relaxation of the sphincter.
