  • Catheter to maintain minimally invasive access for exchanging internal biliary stents
    Patent number: 5259847
    Abstract: A catheter is provided to maintain minimally invasive access for exchanging internal biliary stents. The catheter includes a catheter housing and a catheter obturator. The catheter housing includes an elongated hollow tube with an enlarged flange member at one end, and the diameter of the tube is sized such that a guidewire may pass through it, gaining access to an occluded internal biliary stent. The catheter obturator is used to seal off the hollow tube of the catheter housing for preventing any backflow of bile from occurring through the catheter lumen.
