摘要： A steering mechanism including a steering shaft coupled to a controller which includes a handle and apparatus for manipulating the distal end of the steering shaft. The steering shaft includes a flexible coiled spring having a lead spring fixed in position with respect to a distal end thereof in the distal end of the steering shaft. One or more steering wires is affixed at the distal ends thereof to the lead spring. The steering wires extend through the steering shaft to the controller, and the steering apparatus of the controller is used to place tension on one or both of the steering wires. The attachment of the distal ends of the steering wires to the lead spring may be opposite one another or may be offset for providing greater maneuverability. Tension may be placed on the steering wires by wedges mounted transversely to the controller housing, or by rotation of a shaft mounted transversely to the controller housing, the steering wires being attached to the shaft such that rotation in one direction tenses one steering wire, and rotation in the other direction tenses the other steering wire. Two independently rotatable shafts may be used to separately control the two steering wires.The steering shaft is adapted for insertion into a lumen of a catheter for use in guiding the distal end of the catheter to a treatment site within a patient. The steering mechanism may also be used in conjunction with tools or apparatus which must reach into difficult locations, such as engines or other machines.

摘要： A catheter having an elongated polymeric body with hollow encircling ring electrodes thereon and a method of forming the same are provided by the invention. Ring electrodes are each connected to an external electrical circuit by wires extending through the lumen, the wires each passing through an aperture through a wall of the body and being connected to an interior surface of the ring electrode. The tubular body of the catheter is expanded into a tight interference fit with the interior surfaces of the ring electrodes by heating the body to a temperature approaching its glass transition temperature to permit relief of internal stresses.

摘要： An electrode tip assembly for a catheter is bendable under the control of the user. One portion of the assembly is more resistant to bending than the remaining portions. The variable stiffness directs and concentrates the applied bending forces in the particular region where maximum bending is desired.

摘要： A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.
