Zusammenfassung:Methods for draining pseudocysts and stent delivery systems for use therein are disclosed. An illustrative system may include a catheter shaft having an inflatable balloon affixed to a distal end region thereof. A cutting electrode may be disposed at the distal end of the system and at least one heating electrode may be disposed within the inflatable balloon. A self expandable stent may be disposed about the inflatable balloon. The stent may be formed of a shape memory polymer. The inflation fluid may be heated within the balloon to facilitate expansion of the stent.
