Abstract: The present invention is directed, in part, to an inhaler apparatus with a substrate having medicament deposited thereon, the substrate being configured for electronic release of the medicament. In preferred embodiments, the inhaler comprises a conductive layer and a dielectric layer thereon. In preferred embodiments, the inhaler further comprises a second conductive layer positioned above the substrate without having contact with the substrate. In certain preferred embodiments, the voltage source is connected to the conductive layer in the substrate and the second conductive layer above the substrate.

Abstract: An instrument for interventional flexible tracheoscopy/bronchoscopy, particularly for the treatment of central air passage stenoses under local anesthesia with the aid of a flexible fiber bronchoscope, includes an outer tube and an inner tube, wherein the outer tube and the inner tube can be displaced relative to each other, and wherein at least one guide element is provided for positioning the inner tube relative to the outer tube and a cuff which can be filled with a medium is arranged in the area of the distal end of the inner tube.
