Abstract: A treatment device is provided for applying electrical energy to biological tissue in conjunction with injecting a composition that advantageously diffuses through the tissue. An injector such as a syringe has a reservoir for the treatment composition and injection cannula. The cannula can function as an electrode, and one or more additional electrodes are provided as opposed electrodes. The electrodes can each have tissue penetrating needles, or one or more of the electrodes can have a surface bearing conductive contact part. The syringe or other injector and a drive unit that applies electrical power to the electrodes are operable simultaneously or in a sequence, and can be triggered by switches or automatically upon detection of the injection proceeding to a predetermined state. The treatment device preferably uses a disposable syringe received in a carrier and generally is provided with a non-threatening appearance by minimizing tissue penetration and potential high voltage aspects.

Abstract: The present invention provides a device for the dropwise delivery of a fluid (6) contained in a flexible vial (4; 4'), the device comprising a tubular case (1) capable of surrounding the vial (4; 4'), which casing is provided with a bottom portion (2; 7) whose inner surface lies opposite the outer surface of the bottom wall (42; 42') of the vial (4; 4'), the bottom portion (2; 7) of the casing (1) being equipped with a resiliently displaceable tab (3; 8) which can be moved so as to press against the bottom wall (42; 42') of the vial (4; 4') in order to squeeze the vial (4; 4') and drive out a drop (60) of fluid.
