    摘要： The invention includes methods of and apparatus for endovascularly replacing a heart valve of a patient. One aspect of the invention provides a method including the steps of endovascularly delivering a replacement valve and an expandable anchor in an unexpanded configuration within a sheath to a vicinity of the heart valve; deploying the anchor from the sheath; expanding the anchor with a deployment tool comprising a plurality of actuation elements to contact tissue at an anchor site; and retrieving the anchor into the sheath. Another aspect of the invention provides apparatus including a sheath; a deployment tool comprising a plurality of anchor actuation elements; a replacement valve configured to be disposed within the sheath for delivery to a vicinity of the heart valve; and an expandable anchor configured to be disposed within the sheath for delivery to the vicinity of the heart valve, to be deployed from the sheath, to be expanded by the deployment tool to contact tissue at an anchor site and to be retrieved back into the sheath after having been expanded.

    摘要： The present invention provides for an improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The present invention includes a trap door stent design, a stent delivery catheter assembly, an apparatus for crimping the stent and the method for crimping the stent onto the catheter assembly, and the method for delivering and implanting the stent in a bifurcated vessel. More particularly, the invention relates to a stent having rings aligned along a common longitudinal axis and connected by links, where the stent has a proximal section, a distal section and a central section. The number of rings and the expanded diameter of the sections is varied to create a “trap door” capable of expanding to a slightly larger diameter than the proximal section and distal section of the stent. The stent is implanted at a bifurcation so that the proximal section and distal section are in the main vessel, and the central section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel.
