摘要： Alternative coating compositions and/or methods of coating a medical device. Some examples include coating compositions comprising a polyester urethane and a polyether in a substantially aqueous carrier. The coating composition may be provided as a one or two part system and may be applied by a variety of coating methods, in some cases without a requirement for special equipment or undue industrial hygiene concerns. Additionally, methods of coating medical devices with substantially aqueous coating compositions and the resulting coated medical devices. The composition may be applied to all or part of a medical device by spraying, dipping, brushing, extruding, or the like. After the coating composition has been applied, the substantially aqueous carrier, including any attendant cosolvents or other volatile species, may be removed, typically by heating with optional enhanced air flow although simple evaporation at ambient conditions may also be used.

摘要： A medical device with a corrugated shaping ribbon is provided, The corrugated shaping ribbon (34) allows for the medical device, which may be provided in the form of a guide wire (20) or catheter, specifically a crossing guide wire or catheter, to more easily navigate through the sometimes tortuous pathways of body lumens In addition, the corrugations (42) effectively provide a mechanism by which energy can be stored as the distal tip of the medical device engages a lesion or other area of occlusion within a blood vessel By storing such energy and continuing to apply force, eventually the distal tip (28) extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.

摘要： A composite oxygen ion transport element (1) that has a layered structure formed by a dense layer (10) to transport oxygen ions and electrons and a porous support layer (12) to provide mechanical support. The dense layer (10) can be formed of a mixture of a mixed conductor, an ionic conductor, and a metal. The porous support layer (12) can be fabricated from an oxide dispersion strengthened metal, a metal-reinforced intermetallic alloy, a boron-doped M05Si3-based intermetallic alloy or combinations thereof. The support layer (12) can be provided with a network of non-interconnected pores (14) and each of said pores (14) communicates between opposite surfaces of said support layer (12). Such a support layer (12) can be advantageously employed to reduce diffusion resistance in any type of element, including those using a different material makeup than that outlined above.
