STEERABLE ABLATION DEVICE WITH LINEAR IONICALLY CONDUCTIVE BALLOON

摘要

Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon can have a composite structure with a non-conductive section and a conductive section. The ablation device can have a steering mechanism configured to deflect the balloon.

主权项

1. An ablation device for treating body tissue, comprising:
an elongate shaft having a proximal section, a distal section, and at least one fluid lumen configured to receive an electrically conductive fluid; a steering mechanism disposed within the elongate shaft; an inflatable balloon coupled to the distal section of the shaft and including an interior section in fluid communication with the at least one fluid lumen for actuating the balloon between a collapsed state and an expanded state, wherein at least a portion of the balloon comprises a hydrophilic polymeric material; and at least one electrode located within the interior section of the balloon.
