Intermittent intravesical therapeutic administration system

An intravesical intermittent instillation catheter comprising:

• a tube, dimensioned and shaped for partial insertion into a urinary conduit of a patient, the tube containing a urinary lumen and an instillation lumen, the tube having a distal end and a proximal end, wherein the proximal end has a set of drainage eyelets, formed in a wall thereof, that are in communication with the urinary lumen as well as a set of instillation eyelets, formed at a tip of the proximal end, in communication with the instillation lumen;
• a sheath having a distal end and a proximal end, the sheath being slidably mounted to surround the tube and having first and second axial positions in relation to the tube, wherein, in the first position, the drainage eyelets are exposed and, in the second position, the drainage eyelets are covered by the proximal end of the sheath;
• a valve actuator configured at a distal end of the sheath, the actuator including (i) a slider coupled to the sheath and sliding with the sheath and (ii) an anchor coupled to the tube, each of the slider and the anchor being configured to be grasped by a different hand, wherein movement of the slider away from the anchor causes the sheath to move to the second position so as to cover the eyelets and prevent further flow of urine therethrough;
• and
• a hub mechanically coupled to a distal end of the tube and including an instillation connector coupled to the instillation lumen and a drainage connector coupled to the urinary lumen, wherein the drainage connector is configured to be connected to tubing configured to be coupled to a urinary collection bag and the instillation connector is configured to be coupled to a syringe filled with a medicament for instillation into the bladder;
• so that, when the sheath is in the first position, drainage of urine can proceed through a path including the drainage eyelets, the urinary lumen, the drainage connector, and the urinary collection bag and, when the sheath is in the second position, instillation of the medicament can thereafter proceed from the syringe, through the instillation connector, the instillation lumen, and the instillation eyelets and into the bladder.
