    摘要: A medical device, such as a medical guidewire, having a portion including an inner zone of material and an outer peripheral zone of material surrounding the inner zone of material. The inner zone of material has a first coefficient of thermal expansion and the outer peripheral zone of material has a second coefficient of thermal expansion less than the first coefficient of thermal expansion, wherein at an operating temperature the outer peripheral zone of material opposes expansion of the inner zone of material such that the outer peripheral zone of material exerts a compressive stress on the inner zone of material.

    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 vaso-occlusive device includes a first coil made from a first substantially non-expansile material, and a second coil at least partially co-wound with the first coil and made from a second expansile material. The second coil has a contracted state and an expanded state, in which the second coil expands radially and/or longitudinally. The vaso-occlusive device has increased stiffness when the second coil is in its expanded state.

    摘要: A vaso-occlusive device includes an inner coil made from inner coil wire having a first diameter and formed from a first material, and an outer coil disposed at least partially around the inner coil and made from outer coil wire having a second diameter and formed from a second material. The inner coil has a first pitch and the outer coil has a second pitch. The first diameter, material, and pitch are different from the second diameter, material, and pitch, respectively. The outer coil defines a lumen and the inner coil is disposed at least partially in the lumen. The vaso-occlusive device also includes an intermediate layer disposed between the inner coil and the outer coil, where the intermediate layer includes a biocompatible metal or a biocompatible, swellable polymer.
