    摘要： Methods and devices for successively advancing a plurality of catheters over a guide element to a body tissue are described. In some of the methods, the guide element may be attached to the body tissue, which may be accessible minimally invasively. In certain variations, the guide element may not be detached from the body tissue after the catheters have been advanced over the guide element. The methods may further comprise deploying at least one implant from at least one of the plurality of catheters. In some variations, a method may comprise advancing a first delivery catheter to a first region of a body tissue, deploying a first anchor from the first delivery catheter, where the first anchor is attached to a guide element, proximally withdrawing the first delivery catheter, advancing a second delivery catheter over the guide element, and deploying a second anchor from the second delivery catheter.

    摘要： A method an apparatus for testing the surface of hard disk platters having vertically oriented magnetic domains is disclosed. According to the method of the present invention, all of the magnetic domains on the surface of the disk to be tested are oriented in the same direction, so that the magnetic field intensity adjacent to the surface is ideally uniform. The surface is then scanned using a read head to identify perturbations in the magnetic field intensity which correlate to surface defects.

    摘要： A positionable stent-graft delivery system includes a stent-graft, a tip capture mechanism radially constraining a proximal portion of an anchor stent ring of the stent-graft, and a positioning mechanism for positioning the tip capture mechanism. The positioning mechanism includes tensioner guides and cords. To position the tip capture mechanism, a cord is retracted through the respective tensioner guide, e.g., by the physician. Retraction of the cord, in turn, pulls the tip capture mechanism towards a distal end of the tensioner guide. In this manner, the stent-graft is readily repositioned.

    摘要： An intravascular delivery catheter includes a middle member or manipulator to ameliorate the effect of buckling of the graft cover during the tracking or positioning of the delivery device within a body flow lumen to deploy an exclusion device, such a stent graft. The delivery device/catheter includes a region or regions of lower resistance to bending than other portions of the delivery device, which are positioned, within the delivery device, to preferentially bend the delivery system at locations where buckling will have minimal effect upon the deployment of the exclusion device from the delivery system. The preferential bending is accomplished, by providing a middle member/manipulator that is a rod with laterally oriented slots, having different depth and spacing configurations, or by using a wire coil as a portion of the middle member where the variable stiffness is created either by providing a variable/multiple coil diameter or by using a wire having a variable diameter along its length while the wire coil diameter is relatively uniform.
