Abstract
Electrophysiology catheter apparatus including at least one retractable control wire with a preformed curved resilient foot formed at the distal extremity, slidably advanced and retracted within a longitudinal lumen of a catheter tube for controllably anchoring to a selected endocardial heart tissue. The proximal end of the control wire is formed with a handle to be grasped to slidably advance the preformed resilient foot beyond the distal tip of a catheter to project laterally to contact the adjacent tissue.
