The invention relates to a siloxane-based elastomer intended for controlling the permeation of drugs, wherein the elastomer includes 3,3,3,-trifluoropropyl groups attached to the Si-atoms of the siloxane units. The invention relates also to a method for the preparation of a siloxane-based elastomer including 3,3,3,-trifluoropropyl substituents, where the elastomer is intended for controlling the permeation of drugs. In the method either i) a 3,3,3,-trifluoropropyl-substituted vinyl-functional polysiloxane component and a silicon hydride-functional crosslinking agent are crosslinked in the presence of a catalyst, or ii) a 3,3,3,-trifluoropropyl-substituted polysiloxane component is crosslinked in the presence of a peroxide catalyst.

A dispenser dispenses personal effects such as, panty liners, condoms, wet wipes, tampons, etc., for use by occupants of a particular establishment (home, prison, office, hospital etc.). The personal effects dispenser has a first housing that holds the tampons and the panty liners and dispenses each within a respective opening on the housing with the opening for dispensing the tampons having a hinged door covering the opening. A second housing holds the condoms or wet wipes and has an opening that corresponds to an opening on the first housing whenever the second housing is received within the first housing. A spacer is received within the first housing in order to replace the second housing whenever the second housing is not being used. Various attachment schemes are used to attach the personal effects dispenser to a wall.

A rail stent-graft with increased longitudinal flexibility and sealing properties that is deployable within a body lumen, such as the aorta, for repairing an aneurysm. The rail stent-graft includes an anchoring assembly for securing the rail stent-graft to a portion of the vessel above a junction with another vessel.

The invention provides a double-layer sandwich or multi-layer sandwich multi-latex condom and a preparation method thereof. The preparation method of the condom comprises the following steps: vulcanizing natural latex; emulsifying and dispersing polymer materials such as polyurethane or polyisoprene or butyronitrile or other non-natural latex and making the polymer materials into synthetic latex; and dipping a condom die in the natural latex and the synthetic latex respectively and then drying to finally obtain the double-layer sandwich or multi-layer sandwich multi-latex condom the middle layer of which is made from the natural latex or the synthetic latex, wherein, the innermost layer and the outermost layer of the condom can be made from the same material or different materials. The double-layer sandwich or multi-layer sandwich multi-latex condom of the invention has stretch rate and comfortability of the natural latex as well as high compactness of the synthetic latex, thus being applicable to obstructing penetration of small molecules such as hepatitis, AIDS virus and the like.

The present invention provides positioning mechanisms for devices that cause conduction blocks or ablation in desired areas of tissue. The positioning mechanisms allow for variable geometry of the target sites and enable more accurate therapy at the tissue site.

One embodiment of the invention provides a dental cement composition which includes (a) an acid group-having polymerizable monomer, (b) a polyalkenoic acid, (c) an ion-leachable glass filler, (d) a polymerizable monomer not having an acid group, (e) water, (f) a peroxide, (g) a salt of an aromatic sulfinic acid, and (h) an aromatic secondary amine and/or an aromatic tertiary amine.

Damage indicating packaging is disclosed. A damage indicating material may be applied between inner and outer wrapper layers. When the damage indicating material is exposed to oxygen, excessive heat and/or excessive pressure, the material changes in appearance to thereby alert the user that the package may be compromised. The damage indicating material may include an anti-counterfeiting taggant material. Active and intelligent tamper-evident packaging is thus provided.

The invention provides a condom with a natural antibacterial hydrophilic lubrication coating, which is characterized in that the main hydrophilic components are a polymer or a copolymer formed by one or more monomers of polyacrylamide, polyethylene glycol, polyvinylpyrrolidone, carboxymethyl cellulose, hydroxyethyl cellulose and hydroxypropyl methyl cellulose; and chitosan, a plant extract with antibacterial action and a mixture of the chitosan and the plant extract are added to the hydrophilic lubrication coating. The condom spontaneously generates the lubrication action when meeting the moisten environment of the vagina in the course of the sexual life, and simultaneously absorbs and inhabits the microorganisms of the vagina so as to clean the vagina.

The present invention is directed to a means for storing condoms that will protect and conceal the packaged condoms while they are carried on the person or stored by the consumer subsequent to purchase but prior to use. According to the present invention, the storage means, or condom card, comprises two separable half portions each containing a storage compartment for storing at least one condom therein. The two halves of the condom card are separably attached together by known means in the art, such as juxtaposed tabs and slots.

The present disclosure provides methods and compositions comprising a autophagy inhibitors. Also provided herein are autophagy inhibitors for use as a contraceptive device. Also provided are autophagy inhibitors delivered by an intrauterine delivery system (IUS) to prevent pregnancy or provide contraception. Also provided herein are newly identified compositions for use as autophagy inhibitors.

Described is a process for reducing the antigenicity of sap and products made from the sap of the Hevea brasilisensis plant and other rubber plants. The process involves contacting sap or a latex rubber product with a mono or dialdehyde, a semialdehyde or any chemical containing an aldehyde group, to cross-link antigenic proteins within the sap or the latex product. The cross-linked proteins no longer have the capability to cause an allergic reaction to persons coming into contact with the latex products made by the process of the invention. The cross-linking reaction between the proteins in the latex sap and the aldehyde can take place in the solution used to the final product, or after the final latex product has been formed, or during various intermediate steps of the processes for forming the latex products.

A method and apparatus are provided for fitting a condom-style catheter to a penis of a user. The apparatus includes at least two jaw members movable towards and away from each other. The jaw members, in a first position relative to each other, surround a first portion of the catheter and retain against external surfaces of the jaws a toroidal roll formed of a rolled-up open-ended end sheath portion of the catheter adjoining the first portion. The jaw members are then moved outwardly to a second position relative to each other so that an opening bounded by a wall of the first portion of said catheter between the jaws is shaped and opened up sufficiently to admit placement of an end of a penis therein. The jaws can then be moved inwardly to a position in which the catheter is located on the penis and the toroidal roll can be unrolled from the jaws and thereafter along said penis by a user, so that the penis is located within the catheter. A device for rolling up the sheath portion of the catheter into a toroidal roll is also provided either separately or as part of the above apparatus. This device has movable arms which are inserted into the sheath portion of the catheter and spread apart, so that rolling the sheath portion off the spread arms causes rolling up of the sheath portion into a toroidal roll.
