Abstract:
Featured is a catheter device for ablating tissue that includes an elongated body member having a distal portion and a deflection mechanism operably coupled to the distal portion so as to cause the distal portion to deflect with respect to a longitudinal axis of the elongated body member. Such a catheter device also includes a guide member and a guiding mechanism that is coupled to the elongated body member and is configured so as to guide the guide member. The guiding mechanism includes an exit portion from which the guide member exits during deployment. The exit portion is disposed with respect to the distal portion end so the distal portion deflects from and with respect to the guide member as well as rotating about the guide member.
