Described is a device and method for administration of molecules to tissue in vivo for various medical applications, the device comprising a single hypodermic injection needle and at least two spaced elongate electrodes which provide for the ability, when the needle is inserted into tissue, such as skin or muscle, to pulse tissue with a non-uniform electric field sufficient to cause reversible poration of cells lying along or in close proximity to the track made by the needle upon its insertion into said tissue.

L'invention concerne un dispositif et un procédé pour l'administration de molécules à un tissu in vivo pour diverses applications médicales, le dispositif comprenant une aiguille d'injection hypodermique unique et au moins deux électrodes allongées espacées qui permettent, lorsque l'aiguille est insérée dans un tissu, tel que la peau ou du muscle, d'appliquer des impulsions électriques au tissu avec un champ électrique non uniforme suffisant pour provoquer une poration réversible des cellules se trouvant le long ou à proximité rapprochée de la trace faite par l'aiguille lors de son insertion dans ledit tissu.
