Abstract: A method of manufacturing a metal cannula is disclosed. The method includes the step of providing a metal cannula having a longitudinal axis and defining a fluid channel. Next, the metal cannula is pressed to substantially close the fluid channel and define a first segment and a second segment. In a next step, the metal cannula is cut to separate the first segment from the second segment of the metal cannula. Each of the first and second segments have a pressed edge. The pressed edge substantially seals the fluid channel and has two pressed corners. Afterwards, each of the pressed corners are cut from the pressed edge of the first segment to define a pair of side openings and a distal blunt edge on the first segment. The side openings are in fluid communication with the fluid channel.

Abstract: Methods of fabricating a cannula are disclosed that include, among others, the steps of providing an elongated cannula body, applying a metallurgical-type coating to the cannula body, and forming a bevel on a distal end portion of the cannula body. In one embodiments the step of applying a metallurgical-type coating to the cannula body is performed prior to the step of forming the bevel on the distal end portion of the cannula body. In another embodiment, the step of applying a metallurgical-type coating to the cannula body is performed subsequent to the step of forming the bevel on the distal end portion of the cannula body. Both methods provide extremely sharp cutting edges that are harder and more durable than the underlying substrate.

Abstract: This present disclosure provides a non-coring vial access cannula which has sufficient structural strength that it may be made from a thermoplastic resin instead of metal, thus reducing the likelihood and severity of operator injury by an accidental needle stick. The vial access cannula of the present disclosure has (i) a needle hub suitable for receiving a hypodermic syringe or an IV set (e.g., a Luer lock), (ii) a cannula portion having a centrally disposed lumen, wherein the centrally disposed lumen terminates in one or more distal openings and is in fluid communication with the needle hub, and (iii) a solid tip member distal to the one or more distal openings, wherein the solid tip member has a blade with a cutting edge.

Abstract: The invention relates to a lubricant for medical devices. The inventive lubricant uses silicone epoxy and vinyl ether that both rapidly cure when exposed to ultraviolet light or an intense electron beam. The lubricants formulated with these components in combination with a secondary silicone component and a photoinitator offer improved performance when compared to lubricants formulated from the prior art method of using a RTV+silicone fluid materials. The speed of the UV/EB cure of the new components makes lubricants formed from them more compatible with high speed manufacturing processes by eliminating the delay of prior art lengthy cure steps.
