  • Patent number: 5266071
    Abstract: A method for both disposing an agent in a body organ, preferably a sexual organ, of a human or animal and retrieving a fluid sample containing the agent from the body organ of the human or animal, utilizing a percutaneous access port. A portion of the percutaneous access port is implanted in a body organ of the human or animal and connected to the body organ so that fluid communication exists between the body organ and the fluid chamber of the percutaneous access port, wherein the fluid chamber is not percutaneously implanted. An agent is disposed in the fluid chamber of the percutaneous access port, and flushed to the organ. At a later time, a fluid sample containing the agent is withdrawn from the fluid chamber, and the amount of the agent in the sample is determined.
