Abstract:
1. A locking apparatus for connecting a catheter to a stem of an implantable port, comprising: a collet sleeve comprising: a lockable insert comprising: wherein the lockable insert is configured to be placed at a first locking position at which the cylindrical wall of the lockable insert asserts no or minimal radial compression against the at least one resilient prong of the collet sleeve, wherein the lockable insert is further configured to be moved to a second locking position in which the lockable insert is prevented from returning to the first locking position and at which the cylindrical wall of the lockable insert radially compresses the at least one resilient prong of the collet sleeve so that the at least one resilient prong is deflected radially inwardly, and wherein the center channel of the collet sleeve and the center channel of the lockable insert are adapted to receive the stem of the implantable port and the catheter; wherein the cylindrical wall of the collet sleeve further comprises: a first recess; and a second recess, wherein the first recess of the cylindrical wall of the collet sleeve corresponds to the first locking position of the lockable insert, and wherein the second recess of the cylindrical wall of the collet sleeve corresponds to the second locking position of the lockable insert; wherein the cylindrical wall of the lockable insert further comprises a locking tab adapted to engage the first and second recesses of the cylindrical wall of the collet sleeve; wherein the cylindrical wall of the lockable insert further comprises a live hinge that couples the locking tab of the lockable insert to the cylindrical wall of the lockable insert.
