Abstract
The drainage catheter hub includes a locking cam for securing a suture to maintain an anchor configuration of the distal end of the drainage catheter. The locking cam is rotatable to a first position for securing the suture and a second position for releasing the suture. The locking cam includes a tapered surface which includes a release portion and a securement portion. The release portion allows movement of the suture while the securement portion cooperatively engages the suture in connection with the seat to minimize movement of the suture.
Claims39
A 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 a suture utilized in connection with the drainage catheter selectively secures the distal end of the catheter in an anchor configuration, the drainage catheter comprising:
- a catheter tube having a proximal end and a distal end, the distal end of the catheter tube being configured to be positioned in tissue, cavity, or other location within the body of the patient having an amount of fluid to be drained;
- a suture running the length of at least a portion of the catheter tube and being secured to the distal end of the catheter tube to selectively maintain the anchor configuration of the distal end of the catheter;
- a catheter hub coupled to the proximal end of the catheter tube, the catheter hub comprising:
- a seat having an inner contact surface and adapted to be in contact with a portion of the suture;
- and
- a locking cam adapted to be positioned in the seat, the locking cam having an outside diameter adapted to conform to the inner contact surface of the seat and a tapered camming surface having a release portion and a securement portion, the tapered camming surface extending inwardly from the outside diameter such that the release portion of the tapered camming surface has a greater displacement from the inner contact surface of the seat than the securement portion, wherein the suture can be moved by the user when the suture is located between the release portion and the inner contact surface of the seat and wherein movement of the suture is prevented when the suture is positioned between the inner contact surface and the securement portion.

- a catheter hub coupled to the proximal end of the catheter tube, wherein the catheter hub comprises:
- a camming means for selectively providing release and securement of the suture to maintain or release the anchor configuration of the distal end of the catheter;
- a means for cooperatively engaging the camming means to provide cooperative engagement of the suture when the camming means is in a secured position.
A drainage catheter hub for use with a 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 a suture utilized in connection with the drainage catheter selectively secures the distal end of the catheter in an anchor configuration, the drainage catheter hub comprising:
- a body having a main lumen and a connector for securing the body to a catheter tube;
- a locking cam adapted to allow the user to selectively secure the suture to maintain the anchor configuration of the distal end of the catheter, wherein the locking cam includes a tapered camming surface having a securement portion and a release portion;
- a locking cam seat having a inner surface acconmmodating the locking cam, wherein the suture is positioned between the tapered camming surface and the locking cam seat such that the securement portion of the tapered camming surface and the locking cam seat cooperatively engage the suture when the locking cam is rotated to a securement position.
