Compositions for scavenging oxygen are disclosed. These compositions comprise condensation copolymers comprising predominantly polyester segments and an oxygen scavenging amount of polyolefin oligomer segments. The polyester segments comprise segments derived from typical bottling and packaging polyesters such as PET and PEN. The copolymers are preferably formed by transesterification during reactive extrusion and typically comprise about 0.5 to about 12 wt % of polyolefin oligomer segments. The copolycondensates are capable of absorbing at least 0.4 cc of oxygen per gram of copolymer in the solid state at ambient temperatures and are typically used as layers in films, liners, cups, wraps, bottles, etc. Use of these oxygen scavenging compositions in bottles provides a clear and rigid bottle similar in appearance to unmodified polyester bottles. In a series of preferred embodiments, bottles fabricated with the oxygen scavenging copolycondensates of this invention are over 99.4 wt % polyester and suitable for recycle with other polyester bottles.

The particles are composed of a material such as an absorbing agent, releasing agent and/or activation agent. The polymer composition may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

The invention provides a two-part package and method of use for a pre-attached medical implant and delivery tool system.

In one embodiment the implant comprises a replacement heart valve, and the heart valve is stored inside the wet compartment while the heart valve delivery tool remains dry in the dry compartment.

A method and package for storing a pressurized container which is filled with a drug formulation at a predetermined pressure. The drug formulation includes a mixture of a drug and a propellant. The package which encloses the pressurized container substantially prevents ingression of water vapor and particulate matter into the package while permitting egression of the propellant which may leak from the pressurized container.

Film structures, packages, films and methods of making the same are provided wherein the film structures have a desiccant material incorporated into at least one layer of the film structures and further wherein the film structures can comprise a material for making a peelable seal when the film structures are heat sealed to other film structures. The film structures are utilized for a package to hold a product that may be sensitive to the presence of moisture. The product may preferably be pharmaceutical products, nutraceutical products, or devices such as absorbable sutures or medical stents, although any moisture-sensitive product is contemplated by the present invention.

The invention is directed to the treating, e.g. sterilizing and packaging of medical devices and other articles, particularly such devices and articles which are reactive to oxygen or moisture containing atmospheres. The sterilized package has a container which includes at least one portion which is gas permeable and at least one portion which is gas impermeable and an interior in fluid communication with the gas permeable portion. The container may be sealed by applying an impermeable patch to the permeable portion thereof or by disposing the container in an enclosure formed of impermeable material and sealing the enclosure. After exposing the container to a sterilizing gas, the gas permeable portion may be removed or sealed off from the gas impermeable portion of the container in order to provide a package which is gas impermeable and can protect one or more articles within the interior of the container against environmental gases and moisture.

A container lid with a latch handle is taught that incorporates a drinking lip, having a flared brim, configured to interface with a liquid container. A lip sealing ring is disposed on the drinking lip creating a watertight fit between the lip and the container. A lid body, having lid male threads, is configured to interface with container lid female threads, and the lid body includes a bottom cover which forms a dead air space for insulation purposes within the lid. The lid body incorporates a vertical arched handle with a snap-in hinged spring loaded latch for quick release attachment of the container lid and container securely to an object. A lid sealing ring is disposed on the lid body forming a watertight fit between the lid body and the container drinking lip.

A storage package (1) contains a medical device (7) having a coated surface (8 ) which exhibits a reduced friction when wetted with a wetting liquid and a supply of the wetting liquid (9). The package is adapted such that the coated surface of the medical device is maintained contact with the supply of wetting liquid during storage. A good shelf-life for the medical device is achieved an where the medical device is a urethral catheter the catheter is immediately “ready-for-use” after the package has been opened.

A storage cartridge for dispensing biosensors used in the determination of an analyte in body fluid comprises a hollow body for housing a stack of biosensors having an open top, a flexible conveying member disposed over the open top of the body, the flexible conveying member having an aperture formed therein for receiving a biosensor from the stack of biosensors, a plate adapted to press the sliding conveying member against the open top to form a substantially moisture-impervious seal around the open top of the body and to permit the conveying member to slide between the plate and the open top, and means for biasing the stack of biosensors towards the open top.

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.

An air freshening composition including porous carrier particles having a perfume composition entrapped therein, and a second component selected from an inert filer, hygroscopic agent, binder, coating material, moisture providing agent, and mixtures thereof. The composition may further comprise various optional components such as free perfumes, colorants, disintegrants, water swelling agents, porosity modifiers and mixtures thereof. A method for processing the compositions into a solid article includes the steps of entrapping a perfume in the porous carrier particles, heating and incorporating a carrier or binder material. The compositions may be further processed by optionally incorporating a powder inert filler and forming articles from the mixture. The articles may be formed from the compositions through prilling, extrusion, or compaction amongst other techniques. The air freshening articles and compositions will provide a sustained and controlled release of the perfume compositions over a long period of time without the use of a heat to activate the release. Articles of manufacture including the air freshening articles and various packaging are also disclosed.
