US 2001/0034518 A1 · Sphincter treatment apparatus

Abstract

A sphincter treatment apparatus includes an elongated member having at least one lumen including an inflation lumen and a basket assembly with first and second arms. The basket assembly is coupled to the elongated member and has deployed and non-deployed configurations. An inflatable member is coupled to the elongated member and positioned in an interior of the basket assembly. The inflatable member has deployed and non-deployed states and is coupled to the inflation lumen. In the deployed state, the inflatable member expands the basket assembly to its deployed configuration. A first energy delivery device is positionable in the first arm and advanceable from the first arm to a selected treatment site. A second energy delivery device is positionable in the second arm and advanceable from the second arm to a selected treatment site.
