Drainage catheter with suture lumen

1. A drainage catheter comprising:

a catheter tube comprising a drainage lumen disposed within the catheter tube and extending along a portion of the catheter tube, wherein a distal end of the catheter tube comprises an opening;

a suture lumen disposed along a portion of the catheter tube, the suture lumen comprising a proximal region, a central region distal of the proximal region, a distal region distal of the central region, an exit port at a distal end of the proximal region, and an entrance port at a proximal end of the distal region; and

a suture slidably disposed within the suture lumen along the proximal region, disposed through the exit port, disposed external to the suture lumen along the central region, disposed through the entrance port, and comprising an attachment segment disposed at a distal end of the suture that is fixedly attached to the catheter tube within the distal region of the suture lumen such that the suture lumen is compressed around the attachment segment, wherein the catheter tube is selectively curvable between the attachment segment and the exit port responsive to longitudinal displacement of the suture,

wherein the suture lumen is disposed within an annular wall of the catheter tube, and

wherein the suture lumen is not in communication with the drainage lumen.

2. The drainage catheter of claim 1 , further comprising a catheter hub coupled to a proximal end of the catheter tube, the catheter hub comprising a suture passageway and a suture lock, the suture lock configured to selectively prevent and allow longitudinal displacement of the suture along the suture passageway,

wherein in a secured configuration, the suture lock prevents longitudinal displacement of the suture through the suture passageway in a distal direction.

3. The drainage catheter of claim 1 , wherein the entrance port and the exit port are disposed on the same side of the catheter tube in a straight configuration.

4. The drainage catheter of claim 1 , further comprising a plurality of drainage ports disposed along the catheter tube.

5. The drainage catheter of claim 1 , wherein, when disposed in an anchor configuration, a distal portion of the catheter tube comprises a first curved segment between the attachment segment and the exit port.

6. The drainage catheter of claim 5 , wherein the catheter tube further comprises a distal tip and wherein the distal tip extends distally beyond the first curved segment.

7. The drainage catheter of claim 5 , wherein the first curved segment is disposed adjacent a distal end of the catheter tube.

8. The drainage catheter of claim 5 , wherein the catheter tube further comprises a second curve segment disposed adjacent a middle portion of the catheter tube.

9. The drainage catheter of claim 1 , further comprising at least one radiopaque marker disposed along the catheter tube.

10. The drainage catheter of claim 1 , wherein the attachment segment comprises an etched surface.

11. The drainage catheter of claim 1 , wherein the attachment segment comprises a knot that is compressed by the suture lumen distal to the exit port.

12. The drainage catheter of claim 1 , wherein the attachment segment comprises a bulbous portion that is compressed by the suture lumen distal to the exit port.

13. The drainage catheter of claim 1 , wherein the annular wall comprises a protrusion extending inward along an inner surface of the annular wall that corresponds with the length of the suture lumen.

14. The drainage catheter of claim 1 , wherein the drainage lumen comprises a D-shaped cross-section, wherein the suture lumen is disposed within the thicker portion of the annular wall.
