Electrode assembly for catheter system
First Claim
1. A catheter system comprising:
- a handle,an elongate shaft extending from the handlean electrode assembly carried by the shaft and having a longitudinal axis, a proximal end and a distal end, the electrode assembly comprising;
at least two first struts extending from the proximal end to the distal end of the electrode assembly, each of the at least two first struts having a respective first hinge to facilitate bending of each of the at least two first struts at the respective first hinge of each of the at least two first struts; and
a second strut different from the at least two first struts and extending coextensively with the at least two first struts from the proximal end to the distal end of the electrode assembly, the second strut having a second hinge to facilitate bending of the second strut at the second hinge, the second strut interposed between the at least two first struts such that each of the at least two first struts are adjacent the second strut,wherein a longitudinal spacing of each of the respective first hinge on each strut of the at least two first struts from the proximal end of the electrode assembly is different from a longitudinal spacing of the second hinge on the second strut from the proximal end of the electrode assembly,the electrode assembly being configurable between a collapsed configuration in which each of the first hinge of the at least two first struts and the second hinge of the second strut are at a first transverse distance relative to the longitudinal axis of the electrode assembly, and an expanded configuration in which each of the first hinge of the at least two first struts and the second hinge of the second strut are transversely spaced a second transverse distance relative to the longitudinal axis of the electrode assembly, the second transverse distance being greater than the first transverse distance; and
an actuator associated with the handle and operatively connected to the electrode assembly for selectively configuring the electrode assembly from its collapsed configuration to its expanded configuration.

Abstract
An electrode assembly for a catheter system has a longitudinal axis, a proximal end and a distal end. Multiple struts extend coextensively with each other from the proximal end to the distal end of the electrode assembly. Each strut carries an electrode spaced longitudinally from the proximal end of the electrode assembly. The longitudinal spacing of one electrode from the proximal end of the electrode assembly is different from the longitudinal spacing of another electrode from the proximal end of the electrode assembly. The electrode assembly is configurable between a collapsed configuration and an expanded configuration, with the electrodes being transversely spaced from the longitudinal axis of the electrode assembly a greater distance in the expanded configuration than in the collapsed configuration. In the expanded configuration, the electrodes are transversely spaced from the longitudinal axis of the electrode assembly approximately the same distance.
