Abstract: An electrode catheter for cardiac electrophysiology. An elongated body suitable for intravascular insertion surrounds a plurality of electrode lead wires. A composite electrode comprises a plurality of tip electrodes and defines a margin along a proximal edge. Each tip electrode is electrically connected to an associated electrode lead wire and is adjacent to another tip electrode on at least one side along an axis of the elongated body. Each tip electrode is separated from the another tip electrode by insulation. A cup electrode is electrically connected to an associated electrode lead wire and defines a cavity shaped to overlap the margin of the composite electrode. The cup electrode is fixedly secured to the composite electrode and to a distal end of the elongated body and is separated from the composite electrode by insulation.

Abstract: A bidirectional steerable catheter comprises a catheter body, a tip section and a control handle. The catheter body has a tubular wall, proximal and distal ends, and at least one lumen extending therethrough. The tip section comprises flexible tubing having proximal and distal ends and at least one lumen extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The control handle is mounted at its distal end to the proximal end of the catheter body. The control handle comprises a housing having proximal and distal ends. A distal piston is mounted in the distal end of the housing and fixedly attached to the proximal end of the catheter body. The distal piston is slidably movable relative to the housing. First and second proximal pistons are mounted in the housing proximal to the distal piston. Each of the proximal pistons is slidably movable relative between proximal and distal positions to the housing. The control handle further comprises a movable member capable of selectively and releasably engaging one of the proximal pistons to prevent slidable movement of that engaged proximal piston relative to the housing while allowing slidable movement of the other non-engaged proximal piston relative to the housing so that proximal movement of the housing relative to the distal piston and catheter body results in proximal movement of the engaged proximal piston relative to the distal piston and catheter body. The catheter further comprises a pair of puller wires having proximal and distal ends. Each puller wire extends from the control handle, through a lumen in the catheter body and into an off axis lumen in the tip section. The distal end of each puller wire is fixedly attached to the tip section, and the proximal end of each puller wire is anchored to a separate associated proximal piston in the control handle. In practice, proximal movement of the selectively engaged proximal piston and its associated puller wire relative to the catheter body results in deflection of the tip section in the direction of the off axis lumen into which that associated puller wire extends.

Abstract: A steerable catheter comprises an elongated catheter body and a tip portion. First and second lumens extend through the catheter body and tip portion. The first lumen is open at the distal end of the catheter. The second lumen is off-axis. A tightly wound coil spring is disposed in the second lumen and extends the length of the catheter body. The coil spring is fixed at the ends of the catheter body. A puller wire is slidably disposed within the coil spring, its distal end extending into and fixed at the distal end of the tip portion. The proximal end of the puller wire is attached to a control handle. Manipulation of the control handle results in deflection of the tip portion without deflection of the catheter body.

Abstract: A cardiovascular electrode catheter for use in arrhythmia ablation procedures has a dumbbell-shaped large-tip electrode having an annular recess or indentation. The annular recess divides the electrode into a ball-shaped distal portion and a generally cylindrical proximal portion. Both the distal and proximal portions of the electrode have a diameter substantially the same as that of the catheter body. The recess enables the electrode to grip the mitral or tricuspid annulus or the atrial or ventricular myocardial wall to improve ablation procedures.

Abstract: There is provided a switching unit for interconnecting the leads of a plurality of multiple-electrode catheters, stimulators and recorder channels. The switching unit comprises electrode switch pairs arranged in columns and rows. A separate stimulator is associated with each column and a separate electrode catheter is associated with each row of electrode switch pairs. Each electrode switch of a row is a multiple position switch and is connected to the electrode catheter associated with that row. The electrode switch pairs designate a pair of electrodes which can be monitored by a recorder channel associated with that electrode switch pair or which can be used to deliver an electrical impulse from a stimulator associated with the column of that electrode switch pair. Each column has a stimulator row-selector switch for determining which electrode switch pair, if any, of that column will be used to deliver such an electrical impulse.
