    Abstract: A multi-electrode ablation catheter comprises a plurality of thick-walled gold alloy electrodes mounted on the tip section of an elongated electrophysiology catheter. Each electrode is electrically connected to a switching unit by leads comprising paired copper and constantan wires. The switching unit is electrically connected to an RF generator, a temperature monitor and an ECG monitor. The switching unit enables an operator to switch between a first mode for monitoring ECG and a second mode for delivering RF energy for tissue ablation to a selected electrode and monitoring the temperature of that electrode. The copper wire of the lead delivers RF energy and the copper wire and constantan wire combine to form a thermocouple for temperature monitoring.

    Abstract: A catheter for cardiac mapping includes a tubular catheter shaft having a proximal end, a distal end, and a lumen, the lumen being optionally closed at the distal end. The catheter further includes a plurality of flexible arms which can bow outwardly to form a three-dimensional shape, such as a basket shape. These arms have distal and proximal ends, optionally have a semi-circular cross-sectional shape, and are connected at their proximal ends to the distal end of the catheter shaft. Each arm carries at least one electrode, an electrode lead wire electrically connected to each electrode carried on the arm, and a tubular sheath surrounding the lead wires. The catheter further includes a distal fitting fixing the distal ends of the arms together and a puller wire extending through the lumen. The puller wire comprises a distal end attached to the distal fitting and a proximal end extending out of the proximal end of the catheter shaft whereby the basket shape is expanded outwardly when a force directed in the proximal direction is applied to the puller wire. An electronic recorder can be electrically connected to the electrodes for electrically recording electric signals received by the electrodes.

    Abstract: A steerable catheter, which is adapted to be inserted into a body lumen, comprises a symmetrical cylindrical control handle, an elongate tubular catheter body, and a flexible catheter tip having a lumen offset from the axis of the catheter tip. The control handle comprises a housing having a piston chamber at its distal end. A piston is mounted in the piston chamber and is afforded lengthwise movement. The proximal end of the catheter body is fixedly attached to the distal end of the piston. A puller wire made of nickel-titanium alloy having shape memory is attached to the housing and extends through the piston, through and coaxial with the catheter body and into the offset lumen of the catheter tip where it is attached to the wall of the catheter tip. Lengthwise movement of the piston relative to the housing results in deflection of the catheter tip.

    Abstract: An irrigated tip electrode design includes a shell generally surrounding a plug which jointly define a chamber that is fed with fluid by a lumen. The fluid is distributed to the outer surface of the tip electrode through fluid passages. The chamber is advantageously isolated from a region of the tip electrode occupied by electrical and/or electromagnetic components in the tip electrode. Lumens occupied by the these components terminate in blind holes that have no communication with the chamber. A method of fabricating includes providing a shell configured from a rod to provide an open interior cavity, sealing and partially filling the cavity with a plug to form a chamber, then forming fluid passages between the cavity and an outer surface of the tip electrode, and providing a lumen through which fluid can enter the chamber and exit therefrom through the fluid passages.

    Abstract: A multi-directional electrode catheter comprising an elongated tubular catheter body, a catheter tip section at the distal end of the catheter body and a control handle at the proximal end of the catheter. The catheter body may have a central lumen, and four off-axis lumens symmetrically positioned about the central lumen. A puller wire extends from the central handle through each off-axis lumen and is anchored to the tip section at a selected location. Within each off-axis lumen in the catheter body, there is provided a compression coil in surrounding relation to the puller wire. The compression coil is fixedly attached to the catheter body at its distal and proximal ends. At its proximal end, each puller wire is attached to a movable piston in the control handle. Moreover, each piston is controlled by an operator using a slidable button fixedly attached to each piston. Movement of a selected button results in movement of a selected puller wire and deflection of the tip section in the direction that puller wire.

    Abstract: A bi-directional electrode catheter comprising an elongated tubular catheter body, a catheter tip section at the distal end of the catheter body and a control handle at the proximal end of the catheter. The tip section comprises two pair of generally diametrically opposed off-axis lumens. Two pair of puller wires extend from the handle, through the catheter body, and into the off-axis pair of lumens of the tip section, where they are anchored in the tip section at different locations along the length of the tip section. Compression coils extend through the catheter body in surrounding relation to the puller wires. At their proximal ends, the puller wires are attached to movable pistons in the control handle. Each piston is controlled by an operator using a slidable button fixedly attached to each piston. Movement of selected buttons results in deflection of the tip section into a generally planar “U”- or “S”-shaped curve.
