Membrane systems incorporating silicone polymers are described for use in implantable analyte sensors. Some layers of the membrane system may comprise a blend of a silicone polymer with a hydrophilic polymer, for example, a triblock poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) polymer. Such polymeric blends provide for both high oxygen solubility and aqueous analyte solubility.

The invention is directed to a structured liquid fabric treatment composition comprising as added components one or more silicone-based cationic fabric care ingredients preferably selected from the group consisting of cationic silicone polymers comprising one or more polysiloxane units and one or more quaternary nitrogen units; a structuring system comprising a structuring agent, a nonionic emulsifier and an anionic emulsifier; a cationic scavenging agent for the anionic emulsifier and a liquid carrier.

The present invention relates to a silicone polymer comprising a sulfonic acid component formed from reactive components comprising (i) at least one silicone component and (ii) at least one sulfonic acid-containing component, wherein the sulfonic acid-containing component is comprised of a non-polymerizable, hydrophobic cation and a polymerizable sulfonic acid.

Surgical correction of presbyopia and hyperopia by a circularly distributed assembly of mini-bridges implanted between the interior surfaces of the ciliary muscle and the exterior surface of the lens capsule, for augmenting the transmission of the contraction force of the ciliary muscle / zonule assembly to the lens capsule. The lens is symmetrically squeezed by mini-bridges acting in concert with the ciliary muscle thus changing the curvature of the lens. The mini-bridges are composite synthetic muscles comprising either passive biocompatible mini-bridges made with polymeric gels, silicone polymers or a composite, electromagnetically or mechanically deployable mini-bridges, inflatable balloons or synthetic muscles. The surgical procedure comprises using a ciliary muscle relaxant to stretch the lens / zonules / ciliary muscle assembly. An ultrasonic biomicroscope (UBM) is then used to enable the surgeon to see the area for implantation and the mini-bridges and thus perform endoscopic or incisional surgery to implant the mini-bridges in and around zonular cavities.

Cosmetic emulsion for care and / or makeup, comprising an aqueous phase and a liquid fatty phase dispersed one within the other, said liquid fatty phase comprising at least one silicone oil and being structured with at least one gelling polymer (homopolymer or copolymer) with a weight-average molecular mass ranging from 500 to 500,000, containing at least one moiety comprising: at least one polyorganosiloxane group, composed of 1 to 1000 organosiloxane units in the chain of the moiety or in the form of a graft, and at least two groups capable of establishing hydrogen interactions chosen from among the ester, amide, sulfonamide, carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino, biguanidino groups, and combinations thereof, on condition that at least one of the groups is other than an ester group, the polymer being solid at room temperature and soluble in the liquid fatty phase at a temperature of 25 to 250° C., the aqueous phase, the liquid fatty phase and the gelling polymer forming a physiologically acceptable medium.

The invention relates to a physiologically acceptable composition, especially a cosmetic composition, containing: at least one structuring agent selected from the group consisting of a polyorganosiloxane-containing polymer, a non-silicone-polyamide copolymer, a wax, and mixtures thereof; (b) a hydrocarbyl-functional silicone polymer; (c) optionally, at least one silicone film former; (d) optionally, at least one volatile oil; and (e) optionally, at least one pigment.

The invention relates to compositions containing at least one polyorganosiloxane-containing polymer, at least one volatile non-silicone oil, at least one alkylene polymer wax, at least one silicone film-forming agent and, optionally, at least one long-chain alcohol wax, at least one coloring agent, and / or at least one volatile silicone oil, as well as to methods for using such compositions and to kits containing such compositions.

An apparatus for selectively holding a device, such as a camera, to a surface is disclosed. An internal frame has at one end an attachment means, such as a threaded stud, for selectively attaching the device to the apparatus. The frame further includes a substantially circular flat base that has a first side and a second side. The flat base is substantially conformable to the shape of the surface. A longitudinal shaft is included that extends orthogonally from the first side of the base. A viscoelastic material is fixed about the internal frame and extends beyond a second end of the frame. The viscoelastic material is temporarily adhered to the frame and is capable of selectively adhering the apparatus to the surface. The viscoelastic material preferably includes an R.T.V.-type silicon-based compound, a dimethyl siloxane compound, a borosilicone rubber combination with silicone oil, a silicone polymer combination with boric oxide, or a combination thereof. As such, the viscoelastic material is able to temporarily adhere to most surfaces with enough strength to hold the apparatus and the device thereto, even against the force of gravity and in virtually any typical environmental temperature. At least one lateral frame member is included, projecting away from the longitudinal shaft for increasing the surface area of the frame to which the viscoelastic material adheres. An outer covering surrounds the viscoelastic material and the frame and serves as a barrier between the viscoelastic material and the device.

A transdermal patch for hormone therapy and fertility control has a backing layer, an effective-ingredient-containing adhesive layer adhering to the backing layer and a removable protective film. The adhesive layer includes a progestagenic effective ingredient and an estrogen in an adhesive matrix based on a silicone polymer, a polyisobutylene polymer (PIB), a polyacrylate polymer or a styrene block copolymer with butadiene or isoprene (SBS or SIS). The transdermal patch contains from 0.1 to 10%, based on a total weight of the adhesive matrix, of a progestagenic effective ingredient of formula I: wherein R1 and R2 each represent, independently of each other, H or F; R3 represents CH3 or CF3 and Ar is a group of formula II or III: or a pharmaceutically suitable derivative thereof.

High heat resistant elastic composite laminates, sealants, adhesives, and coatings developed from a resin blend. The resin blend is made up of methyl and optionally phenyl silsequioxane resins selected to produce silanol-silanol condensation silicone polymers formed in a slowly evolving reaction mass containing submicron boron nitride, silica and boron oxide fillers. The required ratio of submicron boron nitride to silica has been discovered for assuring the formation of a high temperature resistant elastic composite blend that will form intermediate flexible ceramic products up to 600 deg C., then continue to form preceramic then dense ceramic products from 600 to 1000 deg C. The thermal yield of the composite is generally greater than 90 wt. % at 1000 deg C. Composite products with different levels of heat transformation can be fabricated within the same product depending upon the thickness of the layers of reinforcement.
