    摘要: An implantable ophthalmic device with flexible, fluid-filled membranes provide dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia without moving parts or reducing the amount of transmitted light. Actuating the device causes the fluid-filled membrane to change curvature, which produces a corresponding change in optical power. For instance, squeezing the edge of the membrane causes the center of the membrane to bulge by an amount proportional to the squeezing force. Alternatively, heating or applying a voltage to the membrane may cause the liquid in the membrane to undergo a phase transition accompanied by a corresponding change in volume that causes the membrane to inflate so as to change the optical power of the device.

    摘要: The present invention provides a method of forming a medical device and medical devices which can be formed in accordance with the method. In one embodiment, the method includes the steps of a) providing a metal fabric formed of a plurality of strands formed of a metal which can be heat treated to substantially set a desired shape; b) deforming the metal fabric to generally conform to a surface of a molding element; c) heat treating the metal fabric in contact with the surface of the molding element to substantially set the shape of the fabric in its deformed state; and d) removing the metal fabric from contact with the molding element. The resulting metal fabric will define a medical device which can be collapsed for passage through a catheter or the like for deployment in a channel of a patient's body. Medical devices made in accordance with this method can have varying structures. In one embodiment, the medical device is carried by a guidewire and has a metal fabric extending between first and second ends, the ends of the device being adapted to slide along the guidewire. The metal fabric has a collapsed configuration in which the ends of the metal fabric are spaced from one another along the guidewire and a preset expanded configuration in which the ends of the metal fabric are positioned closer to one another. The metal fabric will cause the device to elastically substantially resume its preset expanded configuration when released from confinement within a channel in a patient's body.
