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.
An apparatus for treating tissue at or near a sphincter comprising an elongated member having at least one lumen and an expansion device coupled to the elongated member, the expansion device including a basket assembly having first and second arms, the first and second arms in the expanded position having a bow shape and converging at a proximal end and at a distal end, each of the arms having a first and second lumen formed therein, the first lumen configured to convey a fluid, and an energy delivery device movable within the second lumen of each arm from a retracted to an extended position for application of electrosurgical energy to the tissue, each energy delivery device having a penetrating tip to penetrate tissue and couplable to an energy delivery device.
