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 method for attaching a ring electrode to the shaft of the tip section of a catheter comprises passing an electrode lead wire through a lumen in the catheter and out an exit hole in the tip section. The portion of the electrode lead wire extending out of the exit hole is stripped of non-conductive coating and wrapped around the shaft and secured in a clove hitch arrangement. The wrapped electrode lead wire is pulled tight while the material of the shaft is heated to embed the electrode lead wire in the shaft so that its outermost surface is generally flush with the surface of the shaft. The exit hole is sealed and a ring electrode, having a flared skirt is slipped over the shaft to a position over the wrapped electrode lead wire and exit hole. It is then swaged to reduce its outer diameter to about that of the outer diameter of the shaft of the tip section to thereby create a low ohmic connection with the electrode lead wire.

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 split tip electrode catheter is provided having a composite tip electrode comprising multiple electrode elements adjacent to each other. A central irrigation channel extends into the composite tip electrode which branches into transverse irrigation channels in each electrode element. An infusion tube extends from a Luer hub at the proximal end of the catheter through the catheter body and into the central irrigation channel of the composite tip electrode. A temperature sensor preferably a thermocouple may be provided for each electrode element. In use, a cooling fluid is passed into and through the infusion tube and through each of the electrode elements to cool the electrode elements and the interface between the electrode elements and the myocardium or blood so as to prevent the formation of coagulum.

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: The present invention relates to an electrophysiology catheter (an electrode catheter) having an electromagnetic sensor designed internally into the tip portion. The catheter is a size 7 French or 8 French of metal braided construction with preferably three lumens. The catheter has a deflectable tip utilizing an offset lumen with a puller wire, a non compressible coil in the body section and a compressible Teflon sheath in the tip section. The coil is glued to the catheter shaft at both ends of the coil but does not run through the deflectable section, thus deflection of the puller wire which deflects the tip to the coil, keeps the body from compressing and deflecting. The puller wire is soldered to a tip electrode and runs to a control handle. The electromagnetic sensor is mounted internally in the catheter tip by a combination of a hole drilled in the three lumen tip and a hollow bridging that covers the electromagnetic sensor and connects the tip electrode to the catheter shaft. Optionally mounted on the bridging tube are one or more ring electrodes adjacent to the tip electrode. The tip electrode is secured to the end of the bridging tube by an etched Teflon ring which mates the electrode stem to the inside of the ring.
