Locking drainage catheter with rotatable lever handle and release tool

A catheter kit, comprising:

• a drainage catheter, the drainage catheter including:
• a tube;
• a locking catheter hub comprising:
• a hub body attached to the tube;
• a seat having a substantially circular inner contact surface adapted to be in contact with a length of the suture;
• and
• a rotatable barrel adapted to be positioned in the seat such that the rotatable barrel is positioned perpendicular to the axis of the catheter tube, the rotatable barrel adapted to be in contact with the length of the suture, the rotatable barrel having a substantially circular outside diameter, the outside diameter forming a substantially circular contact surface, the outside diameter configured to remain in contact with the seat wherein the contact between the substantially circular inner contact surface of the seat and the substantially circular outside diameter of the rotatable barrel provides a sliding surface to allow rotation of the rotatable barrel relative to the other components of the drainage catheter hub such that the suture is secured when the rotatable barrel is in a first position and the suture is allowed to move when the rotatable barrel is in a second position;
• a locking mechanism associated with the rotatable barrel and being adapted to secure the rotational position of the rotatable barrel when the locking mechanism is in a locked position;
• and
• a release tool configured to unlock the locking hub, the release tool including:
• a first engagement portion configured to interface with the locking catheter hub to facilitate positioning of the release tool with respect to the locking catheter hub;
• and
• a second engagement portion configured to engage a portion of the locking catheter hub to unlock the locking hub to release to the locking mechanism and allow rotation of the rotatable barrel.

A drainage catheter comprising:

• a tube;
• a hub body attached to the tube;
• a seat having a substantially circular inner contact surface adapted to be in contact with a length of the suture;
• and
• a rotatable barrel adapted to be positioned in the seat such that the rotatable barrel is positioned perpendicular to the axis of the catheter tube, the rotatable barrel adapted to be in contact with the length of the suture, the rotatable barrel comprising;
• a substantially circular outside diameter, the outside diameter forming a substantially circular contact surface, the outside diameter configured to remain in contact with substantially the entire inner contact surface of the seat wherein the contact between the substantially circular inner contact surface of the seat and the substantially circular outside diameter of the rotatable barrel provides a sliding surface to allow rotation of the rotatable barrel relative to the other components of the drainage catheter hub;
• and
• a cam, the cam having an engagement portion configured to cooperatively secure the suture between the rotatable barrel and the inner contact surface of the seat;
• and a release portion configured to allow movement of the suture between the rotatable barrel and the inner contact surface of the seat;
• and
• a rotatable lever handle connected to the rotatable barrel, wherein the actuation of the rotatable lever handle moves the rotatable barrel between a first position in which the suture is positioned between the release portion and the inner contact surface and second position in which the suture is positioned between the engagement portion and the inner contact surface of the seat.
