摘要： Disclosed is an apparatus and a method for removable of undesired material from body lumens. The apparatus may be used for fragmenting or removing a thrombus or occlusion from a blood vessel. The apparatus includes first shape segments and second shape segments connected to form a coiled member. A longitudinally extending tether is positioned inside the first shape segments and outside the second shape segments along the length of the coil. Applying a proximal force on the tether produces a change in the shape of at least a portion of the coil from a first generally linear configuration to a second complex three dimensional shape. A method of using the apparatus to engage and remove, or fragment, the thrombus or occlusion is disclosed.

摘要： A vasoocclusive microcoil for therapeutic treatment of a patient's vasculature includes a surface with a plurality of voids or pores therein, and a therapeutic or bioactive material disposed within the plurality of voids or pores. The therapeutic or bioactive material within the plurality of voids or pores operates to accelerate a healing process in the patient's vasculature when the microcoil is introduced into the patient's vasculature.

摘要： The endoluminal device delivery assembly and method for release and deployment of an endoluminal therapeutic device at a desired location for treatment within the vasculature of a patient utilizes an elongated flexible tubular catheter with a tubular distal tip formed of a yieldable material mounted to the distal end of the catheter for releasably holding the proximal end of the endoluminal device. The endoluminal device can be dislodged from the tubular distal tip by a pusher member or pressurized fluid to expel the endoluminal device through at the desired location for treatment within the vasculature of a patient. A flexible coil can be mounted to the distal end of the elongated pusher member to provide for improved tracking.

摘要： The intravascular stent is formed from a composite wire includes an inner core of radiopaque metal, a polymer layer coaxially disposed about the inner core, and an outer metal layer coaxially disposed about the polymer layer. The intermediary polymer layer acts as a barrier material between the inner core and the outer sheath, so that the inner core and outer sheath may be made of dissimilar metallic layers, and the intermediary polymer layer will prevent a galvanic reaction between the inner core and the peripheral metal layer. The intravascular stent has ends flared radially outwardly to prevent radially and longitudinally inward deformation of the ends of the stent when the stent is disposed in a desired location in a patient's vasculature.

摘要： The apparatus for deployment of a therapeutic device such as a micro-coil detachably mounts the therapeutic device to a distal portion of a pusher member. In one embodiment, the therapeutic device is detachably mounted to the distal portion of the pusher member by a connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes through a cutter member such as a cutting ring within the distal portion of the pusher member, for cutting the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.

摘要： The self-expandable aneurysm filling device, system and method provide for placement of the stent into an aneurysm to at least partially fill and stabilize the aneurysm. The self-expandable aneurysm filling device has a compressed undeployed configuration and an expanded three-dimensional deployed configuration, and a severable deployment junction releasably connects the self-expandable aneurysm filling device to a pusher wire. The severable deployment junction can be mechanically, electrolytically, or thermally severed to separate the self-expandable aneurysm filling device from the pusher wire.
