ABSTRACT:
An implantable catheter defining a plurality of fluid exits responsive to a first range of pressure on a fluid agent for delivering substantially the same flow rate of the agent through each of the exits into spaced infusion sites and responsive to a second range of pressure less than a threshold pressure on the agent for inhibiting the flow of the agent from any of the exits into any of the sites. A first pressure in the first range is applied to the agent in the catheter for a first time period and a second pressure in the second range is applied for a second time period to the agent in the catheter so that substantially the same dosage of agent can be applied to each of the sites.
