Title: DRAINAGE CATHETER
Abstract:
The present disclosure relates to a drainage catheter and methods of use for providing improved catheterization procedures, such as during a percutaneous nephrostomy. The drainage catheter includes a body comprising a first tube segment and a second tube segment connected to one another at a curved end portion to form a continuous body structure. An inner surface of the curved end portion includes one or more drainage openings extending therethrough, with an outer surface of the curved end portion free of drainage openings to minimize potential clogging. The openings are in communication with a lumen that extends through the drainage catheter to provide a pathway for removing fluid from the kidney. The drainage catheter is inserted into the kidney via a first insertion site and exits via a second insertion site to minimize the potential for accidental removal of the catheter.
