Estimating the term…
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.
An adjustable rotation limiter device for use with a steerable balloon type dilatation catheter of the type having a flexible core wire extending therethrough, an adapter adapted to be secured to the proximal extremity of a dilatation catheter, the adapter having at least a first arm, a fitting on the first arm, sealing means disposed within the fitting, a thumb screw having a first knob carrying a threaded axially extending member threaded into the fitting and being adapted to engage the sealing means to establish a sealing engagement between the sealing means and the core wire, a torque knob having a second knob carrying an axially extending member threaded into said thumb screw and limit means carried by one of said knobs and having a portion thereof extending over the other of said first and second knobs and serving to limit the rotational movement of the second knob with respect to the first knob.
An adjustable rotation limiter for use with a steerable balloon-type dilatation catheter of the type having a flexible core wire extending therethrough, an adapter adapted to be secured to the proximal extremity of the dilatation catheter, the adapter having a first arm, the core wire extending therethrough and means carried by the first arm for forming a liquid-tight seal between the arm and core wire, first and second knobs, means for securing one of the knobs to the catheter and means for securing the core wire to the other of the knobs, means interconnecting the first and second knobs whereby one knob can be rotated with respect to the other and rotation limiting means carried by said first and second knobs, said rotation limiting means including means carried by first of said knobs and underlying the other of said knobs to prevent rotation of said first knob with respect to the second knob more than a predetermined number of revolutions.
