allowing said fluid to flow into said spring; and bringing the fluid within said spring to a pressure greater than or equal to said threshold dispensation pressure;
wherein said fluid is dispensed from said lumen by flowing radially between said coils and through said exit holes.
62. A catheter for the delivery of fluid throughout an anatomical region, comprising a tube having a plurality of exit holes in a side wall of said tube, said tube being distally closed, said exit holes being sized so that all of said exit holes form a flow-restricting orifice.
63. The catheter of Claim 62, wherein said exit holes are equally sized so that fluid dispensed from said tube flows at a substantially equal rate through all of said exit holes.
