Patent ID: 6934589

Claim:
A system for use in deploying one or more electrode assemblies, comprising: an elongated guiding device having a body extending from a proximal end to a distal end, deployable within a vascular structure; an expandable fixation member coupled to the distal end such that selective expansion of the fixation member secures the elongated guiding device within the vascular structure at a given position an electrode assembly; and a coupling member fixed on to the elongated guiding device body adapted to slidably engage an electrode assembly and having a terminal end such that advancement of the electrode assembly distal to the terminal end causes uncoupling of the electrode assembly from the coupling member within the vascular structure the coupling member and the fixation member being spaced apart along the guiding device body whereby the uncoupling of the electrode assembly is performed independently from the fixation member expansion, whereby the electrode assembly may be located at a predetermined site of implant while the fixation member is expanded.
