    Abstract: Plunger assemblies (20) including a plunger sleeve (34), a plunger rod (22), and an axial protrusion (30) disposed within an inner cavity (40) of the plunger sleeve. Application of a distal force onto the plunger via the plunger rod causes the axial protrusion to contact and apply pressure to an engagement surface (50) in the inner cavity. The engagement surface is configured to receive distal force from the end of the axial protrusion. This causes the plunger to elongate and slightly constrict, thus reducing break loose force and facilitating transition from storage mode to dispensing mode of the plunger.

    Abstract: A method for coating a substrate surface such as a syringe part by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising an organosilicon precursor and optionally an oxidizing gas by providing plasma-forming energy adjacent to the substrate, thus forming a coating on the substrate surface by plasma enhanced chemical vapor deposition (PECVD). The plasma-forming energy is applied in a first phase as a first pulse at a first energy level followed by further treatment in a second phase at a second energy level lower than the first energy level. The lubricity, hydrophobicity and/or barrier properties of the coating are set by setting the ratio of the O2 to the organosilicon precursor in the gaseous reactant, and/or by setting the electric power used for generating the plasma.

    Abstract: Disclosed are plunger assemblies which include a plunger sleeve, a plunger rod and an axial protrusion disposed within an inner cavity of the plunger sleeve. Application of a distal force onto the plunger via the plunger rod causes the axial protrusion to contact and apply pressure to an engagement surface in the inner cavity. The engagement surface is configured to receive distal force from the end of the axial protrusion. This causes the plunger to elongate and slightly constrict, thus reducing break loose force and facilitating transition from storage mode to dispensing mode of the plunger.

    Abstract: A two-phase method is provided for applying a lubricity layer to a surface. The two-phase method comprises a low power deposition step and a high power crosslinking step. The method includes providing a surface of a vessel or an object to be processed. A gas inlet having an internal passage having at least one outlet is provided. An outer electrode is provided. A gaseous PECVD precursor is introduced via at least one outlet of the internal passage. Electromagnetic energy is applied to the outer electrode under conditions effective to form a PECVD lubricity layer on at least a portion of the inner surface. Relative axial motion between the vessel or the object and the gas inlet is provided during at least some time when electromagnetic energy is applied to the outer electrode.
