International Classification:

A61M 1/00

US Classification:

604122

Abstract:

A venting syringe plunger assembly for use with a syringe system allows for venting of gas from the syringe system during use. The plunger assembly includes a hollow outer sleeve having an interior surface, and an inner stem having an exterior surface. At least a portion of the inner stem is disposed within the outer sleeve so as to be movable (e. g. , slidable) within the outer sleeve. A venting passageway is defined between the interior surface of the outer sleeve and the exterior surface of the inner stem. The plunger assembly also includes means for selectively moving the inner stem within the outer sleeve so as to selectively open and close the venting passageway.

Abstract:

Methods and systems for temporarily coating intra-oral devices (e. g. , orthodontic brackets and/or wires) so as to reduce discomfort to soft tissues within a patient's mouth. One embodiment of such a system includes at least one orthodontic bracket or orthodontic arch wire and a two-part polymerizable temporary coating composition for use in coating selected surfaces of the brackets and/or wires. One silicone polymerizable two-part composition includes a vinyl siloxane component, a cross-linking component, and a catalyst activator initially divided between the two parts so that at least one of the components is kept separate from at least one other component (i. e. , all three components are not initially commingled). Upon mixing of the first and second parts, the composition begins to polymerize.
