    摘要: The present invention concerns novel stent apparatuses for use in treating lesions at or near the bifurcation point in bifurcated cardiac, coronary, renal, peripheral vascular, gastrointestinal, pulmonary, urinary and neurovascular vessels and brain vessels. More particularly, the invention concerns a stent apparatus with at least one side opening which may further comprise an extendable stent portion laterally extending from the side opening and at least partly in registry with the wall of the side opening. Devices constructed in accordance with the invention include, singularly or in combination, a main expandable stent comprising at least one substantially circular side opening located between its proximal and distal end openings, which side opening may further comprise an expandable portion extending radially outward from the edges of the side opening; and a branch stent comprising proximal and distal end openings and which may further comprise a contacting portion at its proximal end, and which may optionally be constructed to form either a perpendicular branch or a non-perpendicular branch when inserted through a side opening of the main stent. The stents of the invention are marked with, or at least partially constructed of, a material which is imageable during intraluminal catheterization techniques, most preferably but not limited to ultrasound and x-ray.

    摘要: A method of positioning a main stent at a vessel bifurcation such that a side opening in the main stent is positioned at the ostium of a branch vessel, comprising: positioning a main guidewire in the main vessel such that a distal end of the main guidewire extends past the bifurcation; advancing a stent delivery system to a position proximate the bifurcation, the stent delivery system comprising a catheter with a flexible side sheath attached thereto, wherein the catheter is received over the main guidewire, and wherein the main stent is positioned over the catheter with the flexible side sheath positioned to pass through the interior of the main stent and out of the side opening in the main stent; advancing a branch guidewire through the flexible side sheath attached to the catheter and into the branch vessel; and subsequently, advancing the catheter over the main guidewire while advancing the flexible side sheath over the branch guidewire while viewing relative movement of a marker positioned on the flexible side sheath with respect to at least one marker positioned on the catheter, wherein the relative movement indicates that a portion of the flexible side sheath adjacent the side opening in the main stent is advancing into the ostium of the branch vessel, thereby indicating the position of the side opening of the main stent with respect to the ostium of the branch vessel.

    摘要: A stent delivery catheter comprises a catheter body having a proximal end, a distal end, and a guidewire lumen extending from the distal end to at least part way between the proximal end and the distal end. A balloon is disposed over the catheter body near the distal end, and a stent is positioned over the balloon. The stent has a proximal end, a distal end, and a side opening between the proximal end and the distal end. A side sheath is coupled to the catheter body and has a proximal end, a distal end, and a guidewire lumen extending between the proximal end and the distal end. The proximal end of the side sheath is located between the proximal end of the catheter body and the balloon, and the side sheath exits out of the side opening of the stent.

    摘要: A method for placing a stent into a main vessel such that the stent side hole aligns with a branch vessel ostium comprises inserting a main vessel guidewire into the main vessel and a branch vessel guidewire into the main vessel until a distal end of the branch vessel guidewire passes into the branch vessel. A catheter system is positioned over the main vessel guidewire and the branch vessel guidewire. The catheter system is advanced over the guidewires until the catheter body passes beyond the ostium of the branch vessel and the side member extends into the branch vessel. Marker separation is observed to indicate the catheter body passed beyond the ostium and the side member extends into the branch vessel. The balloon is inflated to deploy the stent with the side hole being aligned with the ostium. The balloon is deflated, and the catheter system is withdrawn.

    摘要: A system for configuring objects such as buttons for screens presented in a touch screen display. The configuration may be automatically based on preset styles. The graphical elements or icons and textual elements may be created once but used multiple times in various places. Multiple graphical and textual elements may be displayed on any button of the screens. The system may be based on the use of a predefined set of button styles that define the layout of each textual and graphical element in basic terms, such as left, right, and center. These styles do not necessarily prescribe a size, but a layout of the elements. The sizing, layout, justification, and clipping of each element may be determined by the button style. For each button style, the assigned textual and graphical elements may be automatically placed for the best or optimal layout and fit.

    摘要: A method of positioning a main stent at a vessel bifurcation includes positioning a main guidewire in the main vessel; and advancing a stent delivery system to a position proximate the bifurcation. The stent delivery system includes a catheter with a flexible side sheath attached thereto and a main stent positioned over the catheter. The flexible side sheath is positioned to pass through the side opening in the main stent. The method also includes advancing a branch guidewire through the flexible side sheath and into the branch vessel; and subsequently, advancing the catheter over the main guidewire while advancing the flexible side sheath over the branch guidewire while viewing relative movement of a marker positioned on the flexible side sheath with respect to at least one marker positioned on the catheter.
