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.

A convenient and preferably wearable system and method for implementing the controlled and sustained delivery of a medical liquid through the tympanic membrane and into the middle ear including port structure that produces a minimal opening in the membrane, a wearable and fixated fluid-conduit structure coupleable to the port structure, a reservoir adapted to contain delivery fluid, and an operationally controllable pump system applied to the fluid conduit structure, and/or an iontophoretic electrode system applied within the fluid conduit structure and to the subject's body, and operable to effect the delivery of reservoir-held fluid or medically active ions through the fluid conduit and port structures to the middle ear.

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 sensor is described for sensing a substance such as for example glucose. The sensor is implantable in the body of a living creature. The sensor comprises a photonic integrated circuit, e.g. silicon-photonics, based radiation processor for spectrally processing radiation interacting with the sample. A continuous monitoring system also is described using such a sensor.

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.

Disclosed are pharmaceutical products for providing pulses of at least one pharmaceutically active ingredient from a patient's stomach, or from a subsequent gastrointestinal site proximal thereto, for absorption thereof at a site(s) more distal in the gastrointestinal tract than the patient's stomach, or than the subsequent gastrointestinal site proximal thereto. The product comprises first, second, and third pharmaceutical dosage forms, each of which comprises at least one pharmaceutically active agent and a pharmaceutically acceptable carrier. The product is formulated such that at least two of the first, second, and third pharmaceutical dosage forms further comprise means for providing temporary gastric-retention of the at least two of the first, second, and third pharmaceutical dosage forms within the patient's stomach, or at the subsequent gastrointestinal site proximal thereto.
