Abstract: A metallic needle cannula is fixed inside a body by laser welding, whereby adhesives are not required. Metallic materials have large absorptions of all electromagnetic radiation, whereby a wider range of possible materials and wavelength is provided for the body and the radiation.

Abstract: The present invention relates to an injection needle for injecting or retracting fluid through the skin of a mammal body and more particularly to non-grinded needle tip-geometry for an injection needle for a reduced penetration force and reduced bleeding. The injection needle comprises of a needle shaft having a centrally located bore disposed along a longitudinal axis connected to a hub by connecting means. The sharpened distal end of the needle shaft has an exit port and two bevels surrounding the exit port. The bevels converge into a tip at the distal end to form a cutting edge and at the proximal end into a heel. The bevels, cutting edge and heel together form the piercing edge that is sharp and continuous without any grinding transitions.

Abstract: A needle magazine for storing and selectively dispensing a plurality of needle assemblies is comprised of a modules that are located adjacent each other and connected together side-by-side. The modules may be box shaped and provided on one side surface with a pin. A side opposite the side surface having the pin has a pin-receiving hole in which the pin of an adjacent module is secured. This allows an individual user to customize the capacity of the magazine based on the user's individual needs by joining as many or as few modules as needed. In some embodiments, a peg is used to secure the modules together. Each module may have a channel that accommodates the peg, thereby allowing a user to arrange the modules side-by-side and secure them with the peg.
