Abstract: An injection assembly includes a syringe barrel (12) having a proximal end and a distal end, a needle hub (20) supporting the needle and coupled to the distal end of the syringe barrel (12). A sleeve (32) is positioned on the syringe barrel and needle hub for sliding between a first position where the needle is covered and a second position exposing the needle. The sleeve (32) is biased to the extended position to cover the needle. The sleeve has a distal end (38) and a proximal end (40). During use, the syringe is positioned against the skin of the patient so that distal end of the sleeve contacts the skin of the patient before the needle so that lateral or angular force applied relative to the surface of the skin is absorbed by the sleeve to inhibit sliding of the sleeve and resist bending of the needle during insertion.

Abstract: A method, including the operations of molding a hollow cannula to create flash on the cannula at parting lines of a mold, retaining the flash on the cannula, and installing the cannula with the flash in a medical device.

Abstract: A delivery device for delivering a medication to a patient includes a catheter with a catheter insertion mechanism, a housing, and a base with a surface for supporting a pump mechanism. A noise dampening member in or on the device inhibits noise and vibrations from the pump mechanism from transferring through the base and housing. The noise dampening member can be an elastomer that is coated on or adhered to the base. The noise dampening member can be molded in or on the base in a suitable location to dampen noise produced by the mechanical component. The noise dampening member can be between the base and the mechanical component or spaced from the mechanical component. The noise dampening member can be molded in a recessed area formed in the base and can have a top face that is recessed, aligned with or project from the top face of the base.
