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.

Abstract: An apparatus treats tissue at or near a sphincter. The apparatus has an elongated member having at least one lumen including an inflation lumen, and a basket assembly including a first and a second arm. An inflatable member is coupled to the inflation lumen and has a deployed and a non-deployed state. In the deployed state, the inflatable member expands the basket assembly into contact with tissue. At least one of the first and second arms of the basket assembly has a fluid lumen having an aperture for conveying a fluid from the basket assembly. A source of fluid is coupled to the fluid lumen for conveyance of fluid through the aperture. The fluid can be, e.g., an electrolytic solution, and/or an anti-infection agent, and/or an echogenic media, and/or a steroid, and/or an anesthetic, and/or a medicament, and/or a tissue cooling agent. The source can be a drug delivery device.
