  • Transition sleeve assembly for catheters
    Patent number: 5984907
    Abstract: A sleeve assembly for use in the transition region of a catheter between a relatively stiff catheter body and a less stiff distal catheter region mediates the difference in stiffness between these two catheter regions.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: November 16, 1999
    Assignee: EP Technologies, Inc.

  • Catheter tip assembly
    Patent number: 5855560
    Abstract: An electrode tip assembly for a catheter is bendable under the control of the user. The distal tip portion of the assembly is progressively less resistant to bending than the remaining portions. The variable stiffness is provided by tapering the width or thickness of a bendable spring component or otherwise providing a progressive change in bending characteristics by notching, dimpling or stepping the thickness of the spring.

  • Catheter having ring electrodes secured thereon
    Patent number: 5855552
    Abstract: 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.
