Silicone hydrogel lens with a crosslinked hydrophilic coating

The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves autoclaving, in a sealed lens package, a silicone hydrogel contact lens having a base coating of polyacrylic acid thereon in an aqueous solution in the presence of a water-soluble, crosslinkable hydrophilic polymeric material having epoxide groups, for a period of time sufficient to covalently attach the crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one epoxide group and one of the carboxyl groups on and / or near the surface of the silicone hydrogel contact lens.

Vapor hydration of a hydrophilic catheter in a package

ActiveUS20060163097A1Little and no possibility of liquid spillageEasy to handleDispensing apparatusDiagnosticsHydrophilic coatingBiological activation
A vapor hydrated packaged catheter assembly and method of manufacturing and distributing same includes a gas impermeable package housing a catheter within a catheter-receiving cavity. The catheter assembly has a hydrophilic coating applied to at least a portion of the outer surface of a catheter tube or shaft which may be surrounded by a sleeve to provide a no-touch, sure grip feature. The catheter assembly is disposed within the catheter receiving cavity of the package together with a limited amount of a vapor donating liquid provided as a source of vapor to activate the hydrophilic coating. The amount of vapor donating liquid is less than the amount that would otherwise be sufficient to cause a spill hazard. It may be loose liquid as a desired percentage of the volume of a tube-receiving portion of the catheter receiving cavity of the package, or it may be contained in a liquid sequestering element. The activation of at least some of the hydrophilic coating occurs solely by reason of exposure of the outer surface of the catheter to a vapor produced by the vapor donating liquid. The distribution of the catheter following manufacture is delayed for a time sufficient to permit the vapor to complete hydration of the entire hydrophilic coating on the surface.

Use of moisture impervious packaging units and package for absorbent articles comprising moisture-sensitive additives

Active additives in absorbent articles, such as sanitary napkins, panty liners, tampons, incontinence protectors and diapers have been found to lose their properties due to taking-up moisture during storage and transportation for instance, when conventional packaging materials are used. The invention relates to the use of a moisture impervious film material for packaging an absorbent article comprising one or more active moisture-sensitive additives. Packaging is effected in film material that has low vapor and gas permeability and in packaging unites that have tight joins or seams.

Packaging solutions

The present invention is directed to new and improved packaging systems for storing ophthalmic devices such as contact lenses and to methods for packaging such ophthalmic devices with aqueous packaging solutions to improve the comfort of the lens during wear. In particular, the present invention is directed to a packaging system for storing an ophthalmic device in an aqueous packaging solution comprising an anionic polymer and a non-ionic polyol. Such solutions can be retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.

Packaging system

InactiveUS20050223679A1Little or no shelf lifeSurgical furnitureDiagnosticsEngineeringMechanical engineering
A packaging system for hydrating sterile devices without comprising the integrity of the sterilization. The packaging system may include an enclosure for enclosing a device requiring hydration, a container containing a hydrate, a base located within the interior of the enclosure and an activating member located within the interior of the enclosure. The container and the device may be located within a receptacle. The receptacle may rest on the base and the activating member may be affixed on top of the receptacle. A force may be exerted on an exterior portion of the enclosure such that the activating member pushes on the receptacle and crushes or ruptures the container. The hydrate located within the container is then released to the device, thereby hydrating the device without breaking the seal of the enclosure. The sterilized environment is therefore maintained and the device is hydrated.

Liquid delivery system with horizontally displaced dispensing point

A method and apparatus is provided for the efficient and controllable delivery of cryogen liquid droplets into thin walled containers before they are sealed, the pressurization of the sealed container caused by the evaporation of the liquid cryogen causing the walls of the container to stiffen. Discharge of the droplets immediately upstream of the container sealing station is facilitated using a horizontal displacement assembly to transport metered droplets from a liquid dosing unit to the point of injection above the container. The horizontal displacement assembly may be provided with internal heaters to prevent freeze up, and a sensor to confirm droplet discharge. It may also be provided with a separate source of heated nitrogen gas, which can be used to back purge the dispensing unit should it become clogged, to melt any frozen liquid occlusions which may have formed in the cryogen supply line. In one embodiment, the solenoid used to actuate the piston regulating the opening and closing of the needle valve, which meters the dispensing of droplets, is mounted in thermal contact with said piston, this placement of the solenoid serving to cool the piston and thus prevent overheating in the case of rapid cycling.
