Abstract
Adjustable rotation limiter device for use with a steerable balloon type dilatation catheter of the type having a flexible core wire extending therethrough and an adapter adapted to be secured to the proximal extremity of a dilatation catheter. The adapter has at least a first arm with a fitting thereon. A sealing is disposed within the fitting. A thumb screw having a first knob carrying a threaded axially extending member is threaded into the fitting and is adapted to engage the seal whereby when a core wire extends through the fitting, the seal, and the thumb screw, the rotation of the thumb screw in one direction will cause sealing engagement between the seal and the core wire. A torque knob having a second knob carrying an axially extending member is threaded into said thumb screw. A rotation limiter is carried by one of the knobs and has a portion thereof extending over the other of the knobs which serves to limit the rotational movement of the second knob with respect to the first knob.
