ABSTRACT:
A method for delivering a medication into a body cavity includes the steps of inflating a flexible bag within the body cavity such that the flexible bag expands to fill most of the void of the body cavity, and injecting medication into the space between an exterior surface of the flexible bag and the cavity wall such that the medication substantially surrounds the flexible bag and fills the remaining void. The steps of inflating the flexible bag and injecting medication are accomplished through subcutaneous injection at a site remote from the body cavity. To accomplish this, a surgically implantable tumor access device includes co-located first and second injection ports, for respectively, receiving a sterile fluid and a fluid medication. A flexible fluid conduit, which includes two coaxial tubes, directs the injected fluids, in a manner providing separate fluid flow paths, to a point adjacent to an inlet for the flexible bag. An inner tube fluidly connects the flexible bag with the first injection port. An outer tube surrounding the inner tube directs medication from the second injection port to medication delivery tubes fixed to an exterior surface of the flexible bag.
