An injection device is disclosed which comprises a housing (140, 240, 440, 740) for a plurality of cartridges (110,310,410,810) each containing a medicament to be administered to a patient. A plurality of needles (120, 220, 320, 420, 720, 820) may be provided in communication with the plurality of cartridges. A delivery mechanism is arranged to deliver medicament through the plurality of cartridges via the plurality of needles. An injection device may comprise a drive member (130) having a cam surface (136) configured to engage a surface of a carrier (150) and rotate the carrier about a pivot (152) and at least one plunger (134) arranged to engage a cylinder in the cartridge.

A device for percutaneous delivery of therapeutic agents includes a first wheel having an axis of rotation, a first axial surface rotably mounted on the head, a second axial surface, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation of the wheel. The device includes a second wheel having an axis of rotation, a first axial surface affixed to the second axial surface of the first wheel, a second axial surface, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation.

A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The motor can oscillate back and forth to cause the needle to oscillate. Structures are described to permit one-handed operation of the device and automatic motor activation based on attaining a desired plunger position. Non-electric motors are described along with a mechanism for axial oscillation of the needle.

The present invention relates to an injector device (20) having a housing (21), a cartridge (22) having a reservoir (28) for medicament, a needle unit (23) comprising a needle (31), and an actuator (26). The needle unit (23) is movably mounted to the housing (21) and prior to use of the injector device the reservoir (28) is sealed from the needle (31). The actuator (26) is configured to move the needle unit (23) into engagement with the cartridge (22) such that the needle (31) is moved into fluid communication with the reservoir (28). A thread is arranged to cause rotation of the needle unit (23) as the needle unit (23) moves into engagement with the cartridge (22).

A system of needles having rudders or keels is provided having perforations, such as kerfs, to allow the needles to be bent by the manipulations of wires imbedded within the needle body. The pulling or pushing of the embedded wires, or stylets, causes the needle tip to be bent, while within the body, to allow the needle to be steered past impediments towards the target necessitating treatment. Wires can be pulled or pushed and in some instances both a push and pull wire are provided to give the needle precision steerability. The needles are provided with a keel or rudder, or can be shaped such as with a teardrop cross-section, to give a degree of stabilization to the course the needle, and attendant tubing, takes within the patient. The kerf cut section of the needle, which can be on one side, two sides or all about the circumference of the needle, allows the needle to be bent one way and then, as needed, another way to allow the needle to be steered within the body.

A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula. The reservoir is connected to the second end of the blunt cannula.

An injector device includes a housing and a cartridge having a reservoir for medicament. The injector device further includes a needle unit comprising a needle, and an actuator. The needle unit is movably mounted to the housing and, prior to use of the injector device the reservoir, is sealed from the needle. The actuator is configured to move the needle unit into engagement with the cartridge such that the needle is moved into fluid communication with the reservoir. A thread is arranged to cause rotation of the needle unit as the needle unit moves into engagement with the cartridge.

The invention relates to a fixing device for fixing a medical, cosmetic, decorative or other article to the skin of a living being, the fixing device comprising the following features: a) a first retaining element having a first piercing point, which is designed to pierce the skin, b) a second retaining element having a second piercing point, which is designed to pierce the skin, the second piercing point being arranged at a distance from the first piercing point, c) a bridge, to which the first and the second retaining element are fastened, d) a fixing portion, which is connected to the bridge or is part of the bridge, the fixing portion being designed to fix the article that is to be fixed.
