The present disclosure provides ablation catheter systems and electrode assemblies and electrode baskets for use in the ablation catheter systems that include an interlinked diamond configuration formed from a plurality of strut assemblies. Each strut assembly includes one or more struts that are manufactured from a thermoplastic or metallic material. The interlinked diamond configuration facilitates reducing an overall length of the electrode assembly. Further, the interlinked diamond configuration facilitates expanding and contracting the struts simultaneously and by the same amount.
