Abstract: An electrode catheter for mapping right sided supra-ventricular accessory electrical pathways comprises an elongated tubular catheter body and a tip portion which comprises a compound curve. The compound curve has a first bend and a second bend which forms a generally circular curve. The plane of the generally circular curve lies transverse to and preferably at an angle of about 30.degree. to the axis of the catheter body. The generally circular curve portion of the tip portion carries a plurality of electrodes. A puller wire extends through the catheter body and into the tip portion, the distal end of the puller wire being fixedly attached to the distal end of the tip portion. A handle is provided at the proximal end of the catheter for controlling longitudinal movement of the puller wire relative to the catheter body. Proximal movement of the puller wire relative to the catheter body results in the angle of the first bend becoming more acute and a decrease in the diameter of the generally circular curve of the tip portion.

Abstract: An autoinflatable catheter is disclosed which comprises an elongated first catheter tube section forming a main catheter body, a short second catheter tube section forming a catheter tip, a balloon support extending between the posterior end of the catheter tip and the anterior end of the main catheter body and an inflatable balloon surrounding the balloon support. The balloon support comprises a rigid cage having a continuous hollow interior and openings for the flow of liquid through the cage to inflate the balloon. The openings are sufficiently large to not significantly restrict the flow of liquid through the openings and to prevent pooling of liquid in the chamber between the cage and the balloon.

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.

Abstract: An electrophysiological mapping device includes an outer catheter, an inner catheter slidable within the outer catheter, and an electronic activation and recording device for electrically activating electrodes on the inner catheter and/or recording electric signals received by the electrodes. The distal end of the inner catheter comprises a plurality of arms that carry electrodes. The arms bow outwardly upon extension of the inner catheter from the outer catheter to form a three-dimensional shape. Each arm has a spine of a superelastic material. Each spine is semicircular in section, and is disposed within a portion of a flexible sheath, the electrode lead wires being disposed in the rest of the sheath. The electrodes are formed from the ends of the insulated electrode lead wires which pass through the sheath, are wrapped around the sheath and then stripped of their insulation. The proximal and distal ends of the spines are fixed to proximal and distal fittings, each having a polygonal segment having flat sides which engage the flat surfaces of the spines and a clamping ring to secure the spines to the segments. A puller wire is attached to the distal end of the three-dimensional shape and passes through the inner catheter to the proximal end of the catheter where it is connected to a deflectable control handle which applies a proximally directed force to the puller wire causing the three-dimensional shape to expand outwardly. The puller wire is coated with TEFLON inside the inner catheter and with polyurethane outside the catheter allowing the inner catheter to translate smoothly inside the inner catheter and to be sealed at its distal end against the flow of blood. Multiple electrode configurations are provided to meet specific ablation and mapping requirements.
