<p>A new and improved tube or catheter for administrating or withdrawing a substance from the human body which can be temporarily attached to the tissue site. The catheter consists of a dual lumen, side-by-side, tube. One lumen is used to administer or withdraw a substance. The second lumen contains an attachment means consisting of a loop of filament extending beyond ends of the lumen in the second tube. During use the surgeon fixes a suture at the tissue site and ties the suture around the filament loop extentding from the distal end of the second tube. The surgeon then grasps the proximal end of the filament and slides the catheter over the filament and the suture until it rests against the tissue attachment site. The filament or suture is then tied around the proximal end of the tube to hold the catheter in place. To remove the catheter, the surgeon cuts the suture where tied to the proximal end of the tube, pulls off the catheter, and slides the suture out of the tissue.</p> |
