<p>A stent (21) is disclosed having a pigtail (33) at its distal end (35) and having a flap (23) acting as a barb at its proximal end (29). Stent (21) includes a catheter body (31) having at least one lumen (43) and having drainage holes (37, 39). The stent may be made of radiopaque polyethylene. The pigtail (33) prevents entire proximal migration of catheter body (31) while allowing spring action to accommodate variations in length, while flap (23) prevents entire distal migration while being radially retractable to facilitate insertion. An alternative embodiment is disclosed having multiple flaps (25, 27) acting as a barb. A method of use is also disclosed.</p> |
