Abstract:
An assembly for treating a tissue region at or near a sphincter comprisingan elongated member having a proximal and a distal end, a basket assembly carried by the distal end of the elongated member, the basket assembly including a first arm with a distal and a proximal section, a second arm with a distal and proximal section, the proximal sections of the first and second arms being mutually coupled to each other and to the elongated member, the distal sections of the first and second arms being mutually coupled to each other, the basket assembly having a deployed and a non-deployed configuration; an inflatable member coupled to the distal end of the elongated member and positioned in an interior of the basket assembly, the inflatable member having a deployed and a non-deployed state, wherein in the deployed state the inflatable member expands the basket assembly to the basket assembly deployed configuration; a first energy delivery device coupled to the first arm and configured to deliver energy to a selected treatment site; a second energy delivery device coupled to the second arm and configured to deliver energy to a selected treatment site; a first lumen in the elongated member that communicates with the inflatable member to convey an inflation medium into the inflatable member to cause inflation; and a second lumen in the elongated member that extends through the inflatable member to accommodate passage of a body through the elongated member and inflatable member and beyond the distal sections of the first and second arms of the basket assembly.
