    摘要: The present invention provides systems and methods for the targeted delivery of a therapeutic agent using expandable devices that are temporarily or permanently placed within the body. Such therapeutic agents may be delivered as a coating on the outer surface of the expandable device. Once positioned at a desired location within the body, the device is expanded such that its drug-coated outer surface establishes direct contact with a target tissue. The expanded device remains in contact with the target tissue for a pre-determined amount of time prior to being withdrawn from the body. Delivery of the therapeutic agent using the expandable device may be followed, or preceded, by delivery of a second expandable device to the same location within the body.

    摘要: The present invention relates to a method for treating obesity, a method for reducing the absorption of dietary fat, and a method for treating hypertriglyceridemia in a patient and to particular polymers for use in the methods or in a manufacture of a medicament. The methods comprise the step of orally administering to a mammal, such as a human, a therapeutically effective amount of one or more fat-binding polymers. The administration of the fat-binding polymer of the invention facilitates the removal of fat from the body prior to digestion, with minimal side effects and low toxicity. In a preferred embodiment, the one or more fat-binding polymers are administered in combination with one or more lipase inhibitors, for example, lipstatin and tetrahydrolipstatin.

    摘要: Bioresorbable thermoset elastomers and methods of making the same are disclosed. In certain embodiments, the thermoset elastomers include soft segments comprising branched polyesters, and hard segments including urethane and/or urea. The thermoset elastomers are made in certain embodiments by curing a branched prepolymer with a cross-linking agent. In certain embodiments, the mechanical properties of the thermoset elastomers are tailored by selecting the average molecular weight of the prepolymer, or by tuning the ratio of prepolymer to the cross-linking agent during curing, or by selecting a cross-linking agent with specific chemical characteristics.
