Claim Text:
1. A medical device, the device comprising: an elongate body including a distal portion, a proximal portion, and a lumen therebetween; a shaft extending through the lumen, the shaft including a longitudinal axis, a distal portion, and a proximal portion, the distal portion of the shaft defining a linear recess that is at least substantially parallel to the longitudinal axis; an electrode array including a distal portion and a proximal portion, the proximal portion of the electrode array being coupled to an inner surface of the lumen and the distal portion of the electrode array being coupled to the distal portion of the shaft, the shaft being slidingly disposed within the lumen alongside at least a portion of the electrode array, advancement of the shaft within the lumen causing the electrode array to transition to an at least substantially linear configuration and retraction of the shaft within the lumen causing the electrode array to transition to an expanded configuration; and a flexible spline including a distal portion and a proximal portion, the spline being slidably disposed within the lumen with the distal portion of the spline being coupled to the distal portion of the shaft, retraction of the spline within the lumen causing the spline to transition to an at least substantially linear configuration and advancement of the spline within the lumen causing the spline to transition to an expanded configuration, at least a portion of the distal portion of the spline being received within the recess when the spline is in the at least substantially linear configuration.
