ABSTRACT:
A bag catheter enabling complete drainage of the bladder characterized by a flexible shaft of rubber, silicone treated rubber, or, preferably, silicone, wherein a distal end is rounded for insertion into the urethra and the opposite, proximate end is structured for interfacing with a urine collector. The shaft includes a drainage tube and an inflation channel, the inflation channel preferably being interfaced with a conventional distension tube with self-sealing membrane. The drainage tube opens at the proximate end of the shaft and has a first drainage portal, preferably also including a conventional second drainage portal as well, at the distal end portion of the shaft. At least one balloon is located at the distal end portion of the shaft, wherein the first drainage portal is located at the site of the at least one balloon. In this regard, the at least one balloon inflates outwardly in relation to the shaft and outwardly around the first drainage portal when pressurized fluid is introduced into the inflation channel. Because the at least one balloon has inflated outwardly around the first drainage portal, urine collecting immediately adjacent the urethro-vesical junction passes thereinto and is discharged from the bladder via the drainage tube.
