Owner:GI DYNAMICS INC
Methods of treatment using a bariatric sleeve
Methods of treatment using a gastrointestinal implant device removably anchored within an animal's gastrointestinal tract. For example, the implant device includes a collapsible anchor for anchoring the device coupled to a proximal end of a flexible sleeve. The implant device can be anchored within the stomach, within the pyloric orifice, and / or distal to the pylorus and extended into the duodenum. All partially-digested food, or chyme, exiting the stomach is funneled through the device. Methods of treatment include treating obesity by one or more of: limiting the absorption of nutrients within the duodenum; delaying the mixing of chyme with digestive enzymes; alter hormonal triggers; and providing negative feedback. Alternatively or in addition, the desired result includes treating a diseases, such as diabetes, or temporarily shielding a portion of the intestine to promote healing within the intestine.

Antioxidant-functionalized polymers
InactiveUS20070010632A1Low yieldReduce sensitivitySuture equipmentsOrganic chemistryAntioxidantOxygen
Methods and compositions are disclosed for the preparation of free radical scavenging polymers and polymer films functionalized with antioxidants. Enzymatic and chemical tailoring of monomers with antioxidants followed by enzymatic polymerization is described. These antioxidant functionalized polymers can increase shelf life and quality of food products, as well as, increase effectiveness of pharmaceutical agents when used as packaging or as coatings on packaging for oxygen sensitive materials. The novel enzymatic covalent coupling of antioxidants to a polymer enhances the free radical scavenging ability of packaging while also inhibiting the escape of the antioxidants, and thus limiting exposure and / or absorption by an individual. In addition to its use in food or pharmaceutical packaging, methods are disclosed for using the antioxidant coupled polymers in a variety of applications including as coatings on the inside of medical devices, such as stents and catheters, which would substantially reduce free radical damage and / or oxygen depletion during medical procedures. Furthermore, through the coupling of antioxidants to biodegradable polymers, controlled delivery and sustained release of an antioxidant to a subject is possible.

A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

A porous SOG film is formed by preparing an organic silane solution containing an organic silane, water and an alcohol, subjecting the organic silane to acid hydrolysis or alkali hydrolysis and then heat-treating the resulting reaction system in the presence of a surfactant to thus form a porous SiO2 film to use for an interlayer insulating film. Alternatively, a porous SOG film is formed by repeating the foregoing step at least one time; or by forming a hydrophobic film on the porous SiO2 film prepared by the foregoing step by the CVD or sputtering technique to thus cap the surface of the porous film; or repeating the porous film-forming and capping steps at least one time. Moreover, after the preparation of the foregoing porous SiO2 film, it is subjected to either of the oxygen plasma-treatment, electron beam-irradiation treatment and UV light-irradiation treatment to remove the unreacted OH groups remaining on the porous film and to thus form a porous SOG film. Further, the foregoing heat-treatment is carried out in the following two stages: in the first stage, the porous film is treated at a temperature capable of mainly removing the water and the alcohol through evaporation thereof; and in the second stage, the porous SiO2 film is treated at a temperature (350 to 450° C.) sufficient for covering at least the inner walls of the holes with the hydrophobic moieties of the surfactant.
