A methodology and apparatus for drug, gene, siRNA, shRNA shRNA peptide,
protein, antibody or any other biomedical therapeutic reagents targeting
in various of solid organs of large animals and humans ex vivo and in
vivo is described. The delivery is assisted with the application of a low
strength electric field network (LSEN). A low strength electric field
network (LSEN) system is used for ex vivo or in vivo delivery of any
therapeutic gene, siRNA, shRNA shRNA protein or drugs into a lung,
pleura, breast, liver, spleen, pancreas, kidney, adrenal, prostate,
testicle, ovary and tumors in chest, abdominal and pelvic cavity.
