摘要： A medical guidewire system comprising a first inner member having a first outer diameter, a second intermediate member having a second outer diameter larger than the first outer diameter, and a third outer member having a third diameter larger than the second outer diameter of the second member. The second member has a longitudinal extending opening to receive the first member for sliding movement with respect to the first member and the third outer member has a longitudinally extending opening to receive the second member for sliding movement with respect to the first and second member. The first member has a first stiffness, the third member has a third stiffness greater than the first stiffness, and the second member is movable to stiffen the guidewire system.

摘要： A medical guidewire system including an inner member having an outer diameter and an outer member having an inner diameter, the inner diameter being larger than the outer diameter. The inner and outer members are relatively slidable to adjust a stiffness of the guidewire system. The lumen of the outer member forms a gap for fluid flow therethrough. A connector has a first end portion connected to the outer member, a second end portion connected to the inner member and a fluid infusion channel communicating with the gap for injection of fluid through the gap to exit a distal portion of the outer member.

摘要： A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel. The apparatus includes a wire having a first configuration and a second deployed configuration, the wire having a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material. A blocking device at a distal portion of the apparatus is movable between a collapsed configuration and an expanded configuration, and is configured in the expanded configuration to block thrombus dislodged by rotation of the wire.

摘要： A vein filter includes a plurality of circumferentially spaced apart elongated legs having opposed proximal and distal leg portions. Adjacent distal leg portions are connected to one another by bridging structure and the legs are adapted and configured for movement between a first position and a second position. In the first position, the proximal leg portions are substantially parallel to one another. In the second position, the proximal leg portions are circumferentially divergent from one another to anchor the filter within a blood vessel. Methods of placing or relocating a vein filter in a vein utilize a catheter balloon to move the vein filter legs between first and second positions. Kits include a vein filter, a catheter balloon for moving the legs of the vein filter, and a delivery sheath for housing the vein filter for delivery within a blood vessel.

摘要： An implantable device for regulating blood flow through a blood vessel comprising an elongated support dimensioned and configured to be implanted in a blood vessel. The support includes a linking member linking axially spaced apart portions to one another. A valve membrane extends between the axially spaced apart support portions and includes first region folded over the first linking member and attached thereto and a second region adjacent the first region and unattached to the first linking member. The second region is movable between a first position to enable blood flow and a second position to inhibit blood flow.

摘要： A catheter has a lumen for a thrombectomy device and at least two balloons of different compliancies. In one embodiment, the catheter is adapted to clear dialysis grafts. One balloon is adapted to expand a stenosis at a venous junction of a dialysis graft and another balloon is adapted to pull a stenosis at an arterial junction of a dialysis graft. A single catheter may be used to perform a dialysis thrombectomy procedure.
