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.
