    摘要： Occluding structures may be created within a body lumen by advancing a length of material distally through the body lumen. By drawing a distal location on the advanced length of material in a proximal direction, the material may be compacted into a structure which at least partially occludes the lumen. The occluding structure may be used to remove kidney stones from the ureter in conjunction with lithotripsy and irrigation.

    摘要： The devices and methods described herein relate to jointless construction of complex structures. Such devices have applicability in through-out the body, including clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen

    摘要： A vasculature device with a wire with a shaped set portion, an electrically conductive path, an electrical connector connecting the wire to the electrically conductive path at a point distal to the shaped set portion, and a hypotube encasing the wire, electrically conductive path and electrical connector is provided. The vasculature device can be actuated from a low-profile configuration to a deployed configuration by heating of the wire, and in particular the shaped set portion of the wire, via application of an electrical current to the wire. The vasculature device is useful in removal of clots, thromboemboli and foreign bodies from the vasculature, and in particular the cerebral vasculature, and as steering wires or guidewires.

    摘要： A mechanism for removing a fluid-filled object from a patient. The apparatus includes a deflation tube with a puncture member at one end of the tube for piercing a hole in the object wall. The apparatus includes a retrieval mechanism slidable within the deflation tube lumen. The retrieval mechanism includes an expansion element that is expandable when positioned within the object from a first configuration with a dimension less than that of the deflation tube lumen to a second or deployed configuration with a dimension that is greater than an outer dimension of the puncture member. The expansion element contacts an inner surface of the inflatable object as the deflation tube and retrieval mechanism are withdrawn from the body cavity. The expansion element may be a T-bar, a foldable anchor, an inflatable member, or another expandable form.
