  • Patent number: 5242430
    Abstract: A rotary handle for attachment to a proximal end of a catheter. The handle comprises a handle member, and a tubular grip member rotatably affixed in generally coaxial relation about a portion of the handle member. An apertured, elastomeric block is provided to permit connection to the proximal end of a catheter. The handle member and grip member are relatively rotatable, to provide corresponding rotation of a connected catheter, typically through a predetermined rotation range, while preventing further catheter rotation to prevent its over rotation while emplaced in a patient. Preferably, the catheter defines a proximal, rigid, tubular tip that passes through the elastomeric block. Also, the catheter may have a steering wire having a zig-zag proximal end positioned within the rigid, tubular tip under compression so that the zig-zag end is frictionally retained within the tubular tip to cause the steering wire to rotate the catheter.
