    • A vaso-occlusive device includes inner, intermediate, and outer elements arranged coaxially. The inner element is a filamentous element, preferably a microcoil. The intermediate element is made of a non-metallic material, preferably an expansile polymer. The outer element is substantially non-expansile and defines at least one gap or opening through which the intermediate element is exposed. In a preferred embodiment, when the intermediate element is expanded, it protrudes through the at least one gap or opening in the outer element and assumes a configuration with an undulating, convexly-curved outer surface defining a chain of arcuate segments, each having a diameter significantly greater than the diameter of the outer element. The expanded configuration of the intermediate element minimizes friction when the device is deployed through a microcatheter, thereby reducing the likelihood of buckling while maintaining excellent flexibility. The result is a device with enhanced pushability and trackability when deployed through a microcatheter.
    • 血管闭塞装置包括同轴布置的内部,中间和外部元件。 内部元件是丝状元件,优选为微线圈。 中间元件由非金属材料制成,优选为可膨胀聚合物。 外部元件基本上是非膨胀的并且限定了中间元件暴露于其中的至少一个间隙或开口。 在优选实施例中,当中间元件膨胀时,其突出穿过外部元件中的至少一个间隙或开口,并呈现出具有起伏的凸形弯曲的外表面的构造,该外表面限定了弓形链节段,每个弧形段具有直径 明显大于外部元件的直径。 中间元件的膨胀结构在器件通过微导管部署时使摩擦最小化,从而降低屈曲的可能性,同时保持优异的柔性。 结果是当通过微导管部署时具有增强的推动性和可追踪性的装置。

    • Disclosed is a micro-coil assembly including: a micro-coil unit which is inserted into an cerebral aneurysm region of a patient and prevents inflow of blood by leading the blood to clot; a coil pusher unit which is arranged adjacent to the micro-coil unit and carries the micro-coil unit to the cerebral aneurysm region of the patient; a tie which connects an end part of the micro-coil unit and the coil pusher unit; and a tensile wire which is relatively movably arranged in the coil pusher unit and coupled to the tie to tense and cut the tie when the micro-coil assembly is separated. Thus, the micro-coil assembly has a simple structure and makes a micro-coil unit and a coil-pusher unit be conveniently and accurately separated, so that the micro-coil unit can be precisely inserted in an cerebral aneurysm region, thereby efficiently meeting a surgical operation of an operator.

    • A coil device is provided with a stretch resistant feature. The device includes a wound coil defining a lumen and a stretch resistant member at least partially received within the lumen. A headpiece is formed by a joining of the coil and a restrictor member, typically by plasma welding. The restrictor member is also at least partially received within the lumen and defines an aperture adapted to movably receive a portion of the stretch resistant member to allow the wound coil to stretch and elongate. The stretch resistant member includes an enlarged portion that is larger than the aperture and adapted to engage the restrictor member to prevent or resist stretching of the wound coil. The restrictor member may be provided as a separate element fixedly secured to the coil wire, or the coil wire may include one or more minor turns adapted to perform the function of the restrictor member.

    • A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes an engagement member attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. A kicker tongue which is formed as an extension of a portion of the wall of the pusher member extends distally from the distal end of the pusher member and is biased so as to lift the retaining ring off of the engagement member to ensure the release of the embolic device when the detachment member is withdrawn from the aperture of the engagement member.
