Patent ID: 7824367

Claim:
A drainage catheter hub for use in connection with a drainage catheter to receive and secure a suture therein, the drainage catheter for use in providing a fluid pathway for draining bodily fluid from a cavity or tissue of a patient, the drainage catheter being configured such that the suture is utilized in connection with the drainage catheter to selectively secure a distal end of the catheter in an anchor configuration, the drainage catheter hub comprising: a housing having a channel to accommodate a suture; a bistable locking mechanism positioned in the housing and being adapted to provide selective securement of the suture, wherein the bistable locking mechanism allows movement of the suture when the bistable locking mechanism is in a first position, and wherein the bistable locking mechanism secures the suture to minimize movement of the suture when the bistable locking mechanism is in a second position, the bistable locking mechanism comprising: an elongate member having a first end; a ball joint component member, having an end comprising a rounded component; and a socket component member positioned between the elongate member and the ball joint component member, the socket component member having an elongate first end positioned within the elongate member and a second end forming a socket to receive and retain the rounded component of the ball joint component member, wherein the suture is threaded through the elongate member and runs along the outside surface of the elongate first end of the socket component member such that the suture is securely sandwiched between the inner portion of the elongate member and the outside surface of the elongate first end of the socket component member to securely retain the suture when the bistable locking mechanism is in a second position and wherein the suture is threaded through the elongate member and runs along the outside surface of the elongate first end of the component member such that the suture is movably positioned between the inner portion of the elongate member and outside surface of the elongate first end of the socket component member to allow movement of the suture when the bistable locking member is in a second position; and a resilient outer layer utilized in connection with the bistable locking mechanism and coupled to the housing, the resilient outer layer adapted to allow the user to actuate the bistable locking mechanism between the first position and the second position to selectively secure and release the suture.
