Application 08/482,674
end anchored to the catheter wall at or near the distal tip
area in such a manner that the application of rotational
torque to the lateral deflection control element produces a
corresponding displacement of the distal tip area in a plane
substantially parallel to the direction of the applied
rotational torque when the distal tip area is deflected from a
linear disposition; and means for applying rotational torque
to the lateral deflection control element.
With reference to Figure 1, Gould discloses a torque
transmitting assembly for guidewires, steerable fixed wire
catheters and the like including an outer tubular member 16, a
balloon 17 secured to the distal end thereof, an inner tubular
member 18, a core member 21 extending through an inner lumen
22 of the inner tubular member, through the interior of
balloon 17 and out the distal end thereof with a flexible coil
tip 23 disposed about and secured to the portion of the core
member 21 which extends out the distal end of the balloon.
See col. 2, line 67 through col. 3, line 4. The proximal end
30 of core member 21 is fixed to a pinion gear 25 which is
driven by a ring gear 24 formed within a rotatable housing 14.
