摘要： A medical device (110) including a catheter shaft (111) and a unitarily and continuously formed portion (108) having a varying durometer, and optionally including an expandable balloon (18, 118). One or both of the unitarily and continuously formed portion (108) and the balloon (18, 118) are made from an irradiation cross-linked or cross-linkable mixture of a polyamide elastomer and at least one additional cross-linking reactant. The polyamide elastomer can be a polyester amide, a polyether ester amide or a polyether amide, and is preferably a nylon block copolymer. The aromatic molecule can be 1,3,5 triethyl benzene; 1,2,4 triethyl benzene; and 1,3,5 triisopropyl benzene. The cross-linking reactant can be: (a) a difunctional material, (b) a trifunctional material, (c) a tetrafunctional material, or (d) an aromatic molecule containing at least two ring substituents, each of the ring substituents having labile hydrogens at a benzylic site therein. The cross-linking reactant can also be diallyl phthalate or meta-phenylene dimaleimide.

摘要： The disclosure relates to a non-intravenous dosage for administration of a liquid biologically active agent. The dosage form contains a solid formulation of the liquid biologically active agent, e.g. propofol, in intimate association with at least one stabilizing agent, e.g. an amphiphilic polymer or surfactant. A liquid biologically active agent is converted to a solid product, e.g. a powder, that can be easily incorporated into a number of different non-intravenous dosage forms. Upon hydration, a nanodispersion or micelle loaded with the active agent is formed. The dosage form can provide a non-intravenous route of administration for active agents that are typically only administered intravenously. Methods, uses, kits and commercial packages related to the non-intravenous dosage form are also disclosed.

摘要： Catheters having an overmolded hub are disclosed. The overmolded catheter hubs may include one or more access hubs that are overmolded with an overmold material. The catheter hub may also be formed as a single piece from the overmold material. The overmolded construction can result in a stronger bond between the catheter body and the hub and can provide for access hubs having sufficient clarity for the observation of air bubbles in a contained fluid. The disclosed catheter hubs may also demonstrate improved balloon deflation rates when utilized with a catheter body having a distal balloon.

摘要： The invention provides compositions and methods for the targeted, in particular, pH targeted, delivery of pharmaceutically active agents in mammals. The compositions comprise pH sensitive diblock copolymers, which permit the release of the pharmaceutically active agent when exposed to an environment having a particular pH. The compositions are particularly useful for the oral delivery of water insoluble pharmaceutically active agents.
