Abstract: This invention is a steerable catheter (10) comprising a resilient deflectable body member (14) having an expandable electrode array (18) at the distal end thereof, and a manipulation handle (12) attached to the proximal end of the body member, the handle including an array deployment device (26). A mandrel (26) is movable through the shaft of the catheter by control movements at the handle to deploy the array or collapse the array as selected. A displacement compensation system (157) is operatively connected to the mandrel such that when the array is expanded, the compensation system biases the mandrel so to keep the array expanded, even during instances of deflection of the distal end. Similarly, the displacement compensation system biases the mandrel to keep the array collapsed when that configuration is selected, even during instances of straightening of the catheter. The displacement compensation system also compensates for overturning the control device in the handle to protect the array and deployment systems.

Abstract: This invention is an expandable electrode array (18) mountable to the distal end of a catheter (10). The expandable array includes a plurality of adjacent elongated segments (20) preformed with proximal, medial and distal hinge portions wherein at least one electrode (22) is mounted on at least one of the segments (20). Each of the plurality of peripheral segments (20) is integrally formed with a resilient conductive longitudinal core encapsulated in an electrically insulated material. A deployment mandrel (26) is operatively connected to each of the respective peripheral segments (20) whereby movement of the mandrel (26) in the proximal direction causes the respective peripheral segments (20) to bend outwardly about the proximal, medial and distal hinge portions to radially expand the segments (20) relative to one another so that the electrodes (22) moves to a predetermined transverse coplanar orientation.
