Arrangements and methods for delivering bioactive agents and/or cells into an extended volume of tissue are disclosed. In one embodiment, a cell-delivering needle (100) arrangement has a tube positioned within a tube (119) and fixedly attached to a wall thereof. In one exemplary method of using the cell-delivering needle, the needle is advanced into tissue, a suspension of cells is passed through a first lumen (112) and out of side ports (116), and a suspension of cells is passed through a second lumen (122) and out of a distal opening (126). Other embodiments are disclosed. |
