  • Drainage catheter anchor locking mechanisms
    Patent number: 6159177
    Abstract: A drainage catheter includes a tubular member with an anchor at a distal end and suture threads extending from the anchor to the proximal ends of the tubular member. A locking mechanism attaches to the proximal end of the tubular member and includes a body with an extension of the lumen. A displaceable body in the locking mechanism body attaches to the proximal end of the sutures to control the amount of slack or tension in the suture threads. An extension of that displaceable body lies externally of the locking mechanism body to enable the operation of the displaceable body without handling the suture threads.
