An infusion device capable of administering liquid medication at a continuous flow rate, and upon user demand delivers a controlled volume dosage of liquid medication at a higher dosage flow rate. The dosage reservoir remains empty until the user actuates it by selectively and temporarily removing the pressure source, such as a spring. During actuation, fluid rapidly flows from the medication reservoir to fill the dosage reservoir. After actuation, the pressure source exerts a higher pressure on the dosage reservoir than the medication reservoir pressure, which results in a temporary higher bolus flow rate. Thus, two distinct flow rates are achieved with one flow restrictor element.

Controlled-volume infusion device

A unit dose, gas-filled syringe is provided which is filled with gas and packaged in a gas barrier material prior to use to increase shelf-life, that is, to minimize gas leakage and dilution of the contents of the syringe. The syringe is filled with a selected gas and sealed inside a container made from a high gas barrier material. The container is also filled with the selected gas. The container material is selected to have a gas transmission rate sufficient to prevent the selected gas from diffusing out of the container into the atmosphere. The volume of gas in the container is greater that atmospheric pressure to prevent atmospheric contaminants from entering the container and syringe.

A tympanic membrane prosthesis is provided that includes, in combination, a generally flat, planar membrane sized to overlay a tear or perforation in the tympanic membrane and having at least one preformed perforation, and at least one mechanical fixation device for fixing the membrane to the tympanic membrane of a patient. Each mechanical fixation device is a tack component including a sharp, piercing distal end, an enlarged proximal end and a shaft extending therebetween. A tack insertion device is provided to guide the tack to and through the tear covering membrane.
