DEVICES AND METHODS FOR BIPOLAR AND MONOPOLAR PROCEDURES

摘要

An integrated catheter assembly comprises a bipolar electrode tool and a monopolar electrode tool. The catheter assembly enables an operator to perform both bipolar and monopolar procedures on tissue without having to withdraw the catheter assembly, without having to remove or replace any part of the catheter assembly, and/or without having to insert any additional tools or parts. The catheter assembly may comprise a switching mechanism such that when one of the bipolar electrode tool and monopolar electrode tool is electrically activated, the other of the bipolar electrode tool and monopolar electrode tool cannot be electrically activated. In one embodiment of a method, the operator uses a single catheter assembly for applying bipolar current for tissue electro-therapy and monopolar current for tissue cutting.
