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： An imageable extendable stent apparatus for insertion into a bifurcating vessel or a vessel opening. The stent apparatus comprises a main stent and a flared stent, which may used individually or in combination with each other. The flared stent may be interlocked with the main stent to provide stent coverage over the entire region of a bifurcation. The main stent of the apparatus may be deployed at the bifurcation point of a vessel, allowing unimpeded future access to the side branch of the bifurcated vessel. The flared stent may be employed at vessel openings. Also disclosed and claimed are methods for implanting the extendable stent apparatus into the bifurcation point or the ostium of a subject vessel.

摘要： The bifurcating double stent apparatus (10) of the present invention comprises a generally cylindrical main stent (12), a generally cylindrical branch stent (15), which are shown as fully dilated in a subject main vessel (8), and a subject branch vessel (7). The main stent (12) is deployed prior to the branch stent (15) which is then aligned with the side opening (16) of the main stent (12), and attached at that location.

摘要： A pericardial access device includes a first tube, a second tube coupled to the first tube, and a biasing mechanism coupled to the second tube. The pericardial access device is moveable between an expanded configuration and a contracted configuration. The biasing mechanism biases the pericardial access device towards the expanded configuration, and the pericardial access device moves towards the contracted configuration when a force is applied to the second tube.
