Abstract
A device and method suitable for remodelling the internal surface of a hollow vessel at least partially occluded by a mass is provided. The device comprises an elongate body having a distal end and a proximal end, the distal end comprising a tip portion located at the distal terminus of the body, and at least one heating element located proximally to the tip portion within the distal end. The at least one heating element is configured to be greater in dimension proximally than distally and thereby tapers towards the distal end. Furthermore, the at least one heating element is arranged so that it can be deployed outwardly from the body of the device and in so doing exert an expansion force on the hollow vessel. The at least one heating element is capable of delivering sufficient energy to remodel the internal surface, and if necessary caused localized ablation, of the hollow vessel without inducing closure of the hollow vessel.
