Abstract
A turn-limiting proximal adaptor for steerable catheter systems comprising a stationary portion and a rotator portion, the rotator portion secured to a guidewire to provide rotational mobility of the guidewire component relative to the catheter component. The proximal adaptor includes a turn-limiter section which has a translational nut threaded onto a central element and limited in longitudinal displacement by a proximal stop and a distal stop. The central threaded element is secured to the stationary portion of the proximal adapter and forms a torsionally rigid body. The translational nut and threaded central element are enclosed within a rotator which is rotatably mounted to said stationary portion and is affixed to the guide wire such that when the rotator is rotated, the guide wire rotates and the translational nut rotates about the threaded central element, in rotational communication with the rotator, and moves in the longitudinal direction until it is stopped by the distal stop means or the proximal stop means. The turn-limiting section is transparent to allow the user to view the rotational displacement of the guide wire by the corresponding longitudinal movement of the tr…
