Control handle with rotational cam mechanism for contraction/deflection of medical device

摘要: A medical device has a distal member with configuration that can be changed by means of control handle assembly employing rotational cam, shaft, and pulley, where the cam is rotationally mounted on portion for rotation user. The operates shaft to move it proximally or distally depending direction which in turn rotates pulley draw release puller wire change device. oriented along diameter handle. two ends extends through axial guide slots sit opposing helical tracks formed inner surface cam. are parallel longitudinal axis therefore maintain shaft's diametrical orientation as rotated distally. Actuation result member's configuration, including deflection, contraction and/or expansion.
