    摘要: Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Open slots in selected portions of the device telescope as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. Closed slits in other portions of the device open as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while remaining open for fluid flow or endothelialization. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of mesh layers having unaligned pore systems which further reduce porosity in desired portions of the deployed configuration.

    摘要: A method of occluding a defect in the wall of a body vessel is provided. An outlet portion of a microcatheter is delivered to the defect, then at least a body portion of a thin film occlusion device is radially expanded from a collapsed orientation to a deployed orientation for engaging the microcatheter and covering at least a portion of the defect. Thereafter, an embolic media is released into the defect from the microcatheter for facilitating thrombosis. The body portion of the occlusion device is substantially porous in the collapsed orientation, but substantially non-porous in the deployed orientation for preventing prolapse of the embolic media into the body vessel.

    摘要: A medical device for placing an embolic device, such as an embolic coil 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 a deflectable 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. When the detachment member is withdrawn from the aperture of the engagement member the engagement member deflects to release the embolic device.

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 member extends 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.
