Catheter placement device

摘要

A slip gripping device for use with an elongated cylindrical member to selectively move that member to any desired longitudinal or rotational position. The device comprises a collet-like member including a plurality of fingers, each of which includes a gripping element at the free end thereof. The collet member is arranged to be grasped and squeezed whereupon its fingers are flexed so that the gripping elements engage the surface of the cylindrical member so that rotary motion imparted to the slip grip device causes the concomitant rotation of the flexible member so that any longitudinal movement of the device causes concomitant longitudinal movement of the member. Release of the collet-like member enables the slip grip device to be slid and rotated with respect to the cylindrial member for positioning anywhere there along.
