    摘要: A drug-eluting stent having a first cell pattern at one end and a second cell pattern on an opposite end. The cells in the first cell pattern have a smaller MCUSA than those in the second cell pattern. An anti-restonic drug can be coated on the first cell pattern and an anti-thrombotic drug on the second, with the anti-thrombotic drug overlaying and covering both the first and second cell patterns. The stent is operatively positionable at a distal graft-vein anastomosis with the first cell pattern adjacent the stenosis, and with the second cell pattern positioned adjacent the vein or the graft.

    摘要: A method for stimulating angiogenesis is provided that includes the use of an electrical output channel adapted to deliver a sub-threshold voltage, a lead that includes a proximal end adapted to be electrically connected to the electrical output channel and a distal end adapted to be placed in the blood conduit where the distal end of the lead is adapted to deliver a treatment agent that stimulates therapeutic angiogenesis, and at least one electrode on the distal end of the first lead.

    摘要: A catheter configured for delivering an agent to a patient's vessel wall, having self-expanding frame, and a method of delivering an agent to a patient's vessel wall. A first catheter has an elongated shaft with an agent delivery lumen and self-expanding frame on a distal shaft section formed of plurality of hollow tubes having joined first ends and free second ends, the free end of each hollow tube having an agent delivery port in fluid communication with the shaft agent delivery lumen and having a hooked tip configured for penetrating the vessel wall in the expanded configuration. Another catheter has a frame around the outer surface of a lining member such as a balloon or a tubular sleeve, such that the frame expanded against the vessel wall and the lining member together define a plurality of pockets between the vessel wall and the outer surface of the lining member.
