Abstract: A programmable injection device, comprising: a nozzle comprising a nozzle head with a fluid input hole and a distinct injection hole, the nozzle head accepts a dose of fluid from the fluid input hole to be injected into the skin of a patient through the injection hole, without use of a needle, a fluid capsule that is connected to said nozzle head and is adapted to provide the nozzle head with multiple doses of fluid for successive injections, without replacing the fluid capsule, an injection head that is adapted to have said fluid capsule and said nozzle head mounted onto it, comprising a first mechanism adapted to forcefully push a dose of a programmable amount of fluid from said fluid capsule to said nozzle head and a second mechanism for injecting by an programmable pressure said dose of fluid from said nozzle head into the skin of a patient in at least one of a programmable velocity or a programmable pressure applied to the skin surface.

Abstract: Devices and methods for delivering a substance to tissue or organs, particularly, the bladder, by a plurality of microneedles The devices may include a delivery tube, a a substance chamber to fill with the substance to be delivered, a plurality of needles, a plunger coupled to a handle movable relative to the tube to deliver the substance to the tissue through the needles, and a protective plate having at least one orifice therein, such that when the device is in a first, resting, position the needle tips are on a first side of the protective plate, and when the device is in a second, operational, position, the needles are on a second side of the protective plate.

Abstract: Razor blades for use in shavers and especially in cartridge type razor blade units. Opposite the cutting edge of an essentially rectangular blade, and integral with this blade, there are provided one or more springy, resilient protrusions, in the plane of the blade. During shaving, these enable the blade, due to pressure exerted on the blade, to move a small distance towards the rear of the housing, thus increasing shaving comfort.

Abstract: An orthodontic buccal tube device adapted to cooperate with an arch wire and comprising a base member for attachment to a tooth, and a body member which is fixed to the base member and which comprises a bore adapted to accommodate an end portion of the arch wire. The device comprises an auxiliary member fixed to or integral with either the base member or the body member and is adapted for cooperation with an end of the wire protruding from the bore to either limit the rearward movement of the wire, or exert a force bringing to the development of a moment in the wire, or both. The auxiliary member is also useful in forming an abutment in the direction of the buccal-mucosa, for ensuring appropriate distance between the buccal-mucosa and the end of the wire so as to avoid injuries to said mucosa.
