Abstract:
A catheter assembly, comprising:a first catheter element, including;a hub having a proximal end, a distal end, a distal planar surface, and a central bore extending longitudinally therethrough;a longitudinal conduit connected at the distal end of the hub that communicates with the central bore; anda distal threaded portion;a second catheter element, including;a hub with a proximal end, a distal end, a proximal planar surface, and a central bore extending longitudinally therethrough;a longitudinal conduit connected at the distal end of the hub that communicates with the central bore; anda proximal threaded portion, wherein the distal threaded portion of the first catheter element is rotatably engageable with the proximal threaded portion of the second catheter element to prevent axial disengagement; andmeans for rotationally securing the first catheter element with the second catheter element wherein the rotational securement means releaseably engages the first and second catheter elements between a locked position for preventing rotational disengagement and an unlocked position for permitting rotational disengagement.
