Abstract: A nozzle for dispensing fluid including a nozzle body having a fluid path therein through which fluid is configured to flow in a downstream direction. The nozzle further includes a valve having a valve body positioned in the fluid path and movable between a closed position wherein the valve body sealingly engages a valve seat to generally block fluid from flowing therethrough, and an open position wherein the valve body is spaced away from the valve seat to generally allow fluid to flow therethrough. At least part of a surface of the valve body positioned upstream of the valve seat is configured to be fluidly isolated from a pressure of fluid in the fluid path upstream of the valve seat when the valve is in the closed position.

Abstract: Techniques are disclosed for reducing the accumulation of gases in an implantable infusion device. In one example, an implantable infusion device (IID) includes a housing, an expandable and contractible reservoir, and a standoff member. The expandable and contractible reservoir is configured to store a therapeutic agent and is arranged within the housing. A first end of the reservoir is configured to collapse toward a second end of the reservoir as the reservoir contracts. The standoff member is interposed between the first end and the second end of the reservoir and is configured to hold at least a portion of the first end offset from the second end when the reservoir is in a contracted state.

Abstract: A projectile syringe has a barrel, a spring loaded power assembly with an attached plunger, a notched plunger shaft terminating in a knob and a breach plug secured to the barrel. The spring loaded power assembly has a cylindrical sleeve with four dissected fingers, two projections on the sleeve's outer cylindrical surface securing a compressed compression spring. A cylindrical weight is captured within the sleeve by four fingers. The user attaches a needle and draws a desired amount medicament. The plunger shaft is broken flush against the breech plug. The user attaches a stabilizing tail to the breech plug end and the projectile syringe is aimed at a target animal. Stopping the syringe displaces the cylindrical weight, allowing the four fingers to displace. The proximal projections move inward, allowing the compressed compression spring to expand to the fixed breech plug, pushing the piston to deliver medicament to the animal.
