    摘要: A method of forming a composite structure for an ion transport membrane in which a filler substance is applied to one surface of a porous support layer in order to plug pores and prevent coated ion conducting material from penetrating the pores to reduce the amount of gas diffusion. Prior to coating of the surface with layers that may be oxygen ion conducting layers, excess filler substance is removed. After the coating of the one surface, the filler substance is removed from pores.

    摘要: A medical device with a corrugated shaping ribbon is provided. The corrugated shaping ribbon for the medical device, which may be provided in the form of a guide wire or catheter, specifically a crossing guide wire or catheter, provides 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 extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.
