Patent ID: 7909814

Claim:
A drainage catheter hub for use with a drainage catheter tube which provides a fluid pathway for draining bodily fluid from a cavity or tissue of a patient, the drainage catheter being configured such that a suture utilized in connection with the drainage catheter selectively secures the proximal end of the catheter in an anchor configuration, the catheter hub configured to be coupled to the distal end of the catheter tube, the drainage catheter hub comprising: a hub body comprising a seat having a substantially circular inner contact surface and adapted to be in contact with a portion of the suture while permitting a loose portion of the suture to extend therefrom such that it can be grasped by a user; a rotatable barrel, having an axis of rotation and having an outside diameter forming a substantially circular contact surface configured to conform to the substantially circular inner contact surface of the hub body, the rotatable barrel further comprising a cam surface having a release portion and a securement portion, wherein the release portion extends inwardly from the outside diameter of the rotatable barrel a sufficient amount to permit movement of the suture when the suture is positioned between the release portion and the seat and wherein the securement portion is positioned adjacent the seat for cooperatively clamping the suture when the suture is positioned between the securement portion and the seat; a rotatable lever handle integrally coupled to the rotatable barrel to rotate the rotatable barrel between a position in which the securement portion contacts the suture to prevent movement of the suture and a position in which the release portion is positioned adjacent the suture to allow movement of the suture; a locking mechanism provided in connection with the rotatable lever handle, the locking mechanism configured to secure the rotational position of the rotatable lever handle, wherein the locking mechanism comprises one or more slots on one of the rotatable barrel and the hub body and one or more projections on the other of the rotatable barrel and the hub body, the one or more slots cooperatively engaging the one or more projections when the locking mechanism is actuated; and a release mechanism comprising a release slot allowing the user to disengage the one or more projections and the one or more slots for allowing movement of the rotatable lever handle subsequent to actuation of the locking mechanism, wherein the user urges the rotatable lever handle in a direction parallel to the axis of rotation of the rotatable barrel to actuate the locking mechanism.
