Abstract
A collapsible electrode catheter assembly (10) having a delivery system (12) for controlling a catheter guide tube (16) having a catheter distal end assembly (22) thereon. The catheter distal end assembly (22) has an electrode structure (28) on an expanding assembly (34) for enlarging the electrode structure (28) in an expanded condition. A balloon structure (48) is used to expand and contract the expanding assembly (34) when an inflation medium (64) is alternately introduced into and withdrawn from the balloon structure (48).
