    摘要： This is an artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space adjacent to and extending from a body lumen in a mammal. The includes at least one occlusion device and a retaining device for blocking the migration of the occlusion device out of the occlusion site. The retaining device is radially expandable at a retaining site adjacent the body space to be occluded to a diameter that is sufficient to engage the body lumen wall at the retaining site and form a barrier across the entrance zone of the body space to be occluded. The expanded retaining device also forms a lumen for flow through body lumen at the retaining site. At least one semi-penetrable space may also be provided in the retaining device, allowing introduction of occlusion devices into the body space to be occluded, but preventing subsequent migration of the occlusion devices out of the body space. This semi-penetrable space may also be distensible to allow for delivery of occlusion devices therethrough. An introducer wire or a tapered-tip delivery catheter may be used to distend the distensible space and deliver the occlusion devices. The retaining device structure may further include a radiopaque metal wire wound into a primary helix over an inner core member made of a superelastic alloy of nickel and titanium. An implantable medical device assembly is also provided, having the structure described for the retaining device of the novel artificial occlusion kit, and which is attached to an elongate pusher via a sacrificial link that is electrolytically dissolvable.

    摘要： This is a device for capturing and removing bodies or articles from within a vessel, such vessels as may be found in the vascular system or the genital urinary tract. It includes a core wire which has attached at its distal end a plurality of fibers. The core wire may be introduced through a catheter to a selected site and further advanced and "twirled" to engage the offending foreign body. The retriever and its targeted foreign body are then withdrawn using the catheter.

    摘要： Electrolytically detachable implantable devices and methods of delivering the same to a treatment site. An assembly includes an implantable device, such as a vaso-occlusive coil, a conductive deployment mechanism, such as a conductive pusher or wire, and a temporary connection between the deployment mechanism and the coil in the form of an electrolytically detachable junction. The detachable junction includes fine wires, e.g., stainless steel wires having a small diameter of about 0.00001″ to about 0.0025″, for example, about 0.0005″. The pusher or wire is used to deliver the implantable device through a catheter and to a desired location or treatment site. After the implantable device is properly positioned, electrical current is applied to the fine wires, thereby simultaneously disintegrating the fine wires and leaving the coil at the treatment site.
