Patent ID: 7736331

Claim:
A drainage catheter for use in providing a fluid pathway for draining bodily fluid from a patient, the drainage catheter being configured to form a pig-tail-type loop at its distal end to secure the drainage position of the distal end of the catheter, the drainage catheter comprising: an elongate hollow tube having a proximal end and a distal end; a drainage lumen configured to allow passage of bodily fluids from the distal end of the elongate hollow tube to the proximal end of the elongate hollow tube; a hub positioned in fluid communication with the drainage lumen at the proximal end of the elongate hollow tube; an anchor loop adapted to be formed in the distal end of the elongate hollow tube such that the anchor loop has an inside diameter and an outside diameter, the anchor loop adapted to secure the drainage position of the distal end of the elongate hollow tube in a patient; a plurality of drainage bores positioned on the inside diameter of the anchor loop; and a stylet threaded along a length of the hollow tube, the stylet terminating at a position proximal to the drainage bores on the inside diameter of the anchor loop; a suture and a suture lumen positioned in one of the first and second sidewalls of the elongate hollow tube wherein the suture and suture lumen are positioned in the one of the first and second sidewalls of the hollow tube a determined amount of displacement from the inside diameter of the anchor loop such that the suture extends through the portion of the hollow tube coterminous with the drainage bores without the suture obstructing the passage of fluids into the drainage bores or the hollow tube or through the drainage lumen of the hollow tube and wherein the suture is threaded such that a single length of suture is positioned along the length of the hollow tube, the suture having a weld to secure one portion of the suture to another portion of the suture, the weld configured to selectively secure the suture to the stylet to selectively secure the configuration of the anchor loop.
