ABSTRACT:
A medical stent provides an active agent to a patient's body while simultaneously maintaining an open passageway within the body of the patient. The stent includes a first segment, a second segment, a connecting segment disposed between the first and second segments, and the active agent. The active agent may be a hemostatic agent that stops or controls bleeding by coagulation, or any other medical drug, such as, for example an antibiotic or an anticoagulant. When the stent is properly positioned within the patient's urinary system, the first segment is located on one side of the external sphincter and the second segment is located on the other side. The connecting segment is sized to extend through the external sphincter to couple the first and second segments together while not interfering with the normal operation of the external sphincter.
