    摘要： This invention is an exceptionally flexible, ultrasoft vaso-occlusive or embolism forming device. It is made of a radiopaque material which may be braided or coiled to form a long, thin threadlike device having little rigidity or column strength. The diameter of the device may be less than about 0.010 inches. The device is sufficiently flexible and small that it may be hydraulically delivered to a site within the vasculature of the human body using an injected drug or fluid flush through a catheter. The device assumes a loose, random mass of threadlike material after being ejected from the catheter tip at the chosen vascular site. The device (whether coil or braid) may be used alone or in conjunction with larger coils or braids to achieve a denser occlusion or as a substrate to localize the subsequent infusion of tissue adhesives, particulate embolization devices, or chemotherapeutic agents in abnormal blood vessels and tissues or for the temporary occlusion of blood vessels during types of diminished blood flow testing. The invention also include processes for introducing the devices into the human body.

    摘要： A catheter guide wire comprising: a flexible, torqueable proximal wire section, a more flexible intermediate section with a flexible polymer tube covering, and a most flexible distal end section. A helical ribbon coil is wrapped about the intermediate core segment between the wire core and the polymer tube covering to increase radiopacity and improve torque transmission while retaining flexibility.

    摘要： Devices and methods for coupling, delivery, detaching and controllably releasing a medical implant, and methods for the assembly and use of the devices, provide for mechanically simple and rapidly operated release of the implant without disturbing its precisely selected position. Embodiments of various aspects of the present invention employ, among other structures, a loop or other aperture-bearing engagement element releasably held by a mating retaining element, in some instances with the assistance of a member for constraining the engagement element relative to the retaining element. In another aspect, the loop or other aperture-bearing element may be at least temporarily placed in a tensile state to maintain coupling of the implant prior to release. Embodiments of the invention permit release through a practitioner actuation, such as causing one or more rotations that lead to the withdrawal of the retaining element from the loop or aperture-bearing element. Release may be immediate, or near-immediate, while the loop, which may in various embodiments be of a flexible material, is left behind with minimal or no disturbance of the implant.
