摘要： An endoprosthetic implant is formed from a plurality of separate individual components that are inserted sequentially and transluminally into a bifurcated vascular region with each component being deployed in sequence by a sequence of catheter-like deployment devices. The separate components are placed relative to each other to define a bifurcated endoprosthesis. In one embodiment the deployment device includes a tubular sheath for maintaining the radially expandable tubular implant in a contracted configuration and a gripping device including a cup and a gripping member that cooperate to define an annular space by which the trailing end of the implant can be securely held by the deployment device during positioning of the device.

摘要： A stent-graft comprising an expandable stent and a plurality of graft segments, each graft segment having a first end attached to the stent and a second end not attached to the stent. In one embodiment, the plurality of overlapped graft segments form a continuous conduit wherein each overlap between axially adjacent graft segments comprises a fluid-tight seal when the stent in the radially expanded configuration sandwiches the graft segments against a wall of a body lumen. In another embodiment, there are one or more discontinuities in the plurality of graft segments. The discontinuities may be aligned with branch lumens. The graft segments may be cut perpendicular to the stent-graft axis, or on a bias. A delivery system for and method of deploying the stent-graft are also claimed.

摘要： The vascular graft includes a PTFE tube having non-expanded portions formed from sintering a PTFE green tube extrudate. The non-expanded portions are distributed longitudinally along the PTFE tube. The PTFE tube also has expanded portions formed subsequent to the sintering of the PTFE green tube extrudate. The expanded and non-expanded portions are integral with one another, and alternate with one another along the length of the PTFE tube. The expanded and non-expanded portions each have a respective stiffness, where the stiffness of the non-expanded portion is greater than that of the expanded portion.

摘要： Apparatus and method for positioning a probe through a catheter wherein a sensing element on the probe is located outside the catheter but is spaced from the luminal surface of the blood vessel to prevent any adverse effect on the sensor measurement. A standard introducer catheter may be used and a support tube is provided around a portion of the probe and is slidably engagable within the catheter lumen for positioning the probe against an anterior wall of the catheter, away from a posterior vessel wall on which the catheter lies. In a second embodiment, a portion of the support tube extends outside the distal end of the catheter to prevent any possible contact between the sensing element and posterior vessel wall.
