A reversible lockable drainage catheter for use in draining excess bodily
fluid in a tissue having a catheter tube with a proximal end and a distal
end, and a lockable hub positioned about the catheter tube. A suture of
the drainage catheter can be reversibly tensioned, and locked in the
tensioned conformation by depressing one or more surfaces of the lockable
hub. The suture can then be released also by depressing one or more
surface of the lockable hub, or by implementing one or more additional
safety release mechanisms. For example, a safety release can be pulled in
a proximal direction to release a tensioned suture. Similarly, the suture
can be tensioned to a point that stretches an attachment point of the
drainage catheter tube, and also causes the suture and safety release
mechanism to disengage.
