Abstract: The present invention is directed to a stent for use in a bifurcated body lumen having a main branch and a side branch. The stent comprises a radially expandable generally tubular stent body having proximal and distal opposing ends with a body wall having a surface extending therebetween. The surface has a geometrical configuration defining a first pattern, and the first pattern has first pattern struts and connectors arranged in a predetermined configuration. The stent also comprises a branch portion comprised of a second pattern, wherein the branch portion is at least partially detachable from the stent body.

Abstract: 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.

Abstract: 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 flexibl

Abstract: 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.

Abstract: A system for treatment of a bifurcation of a body lumen, the bifurcation having a main vessel and a branch vessel, the system includes a catheter having a main catheter shaft and a first balloon associated with the main catheter shaft, a side sheath and a second balloon associated with the side sheath, and a stent including a generally cylindrical body and a branch portion. A method is also described which includes advancing a catheter system through the main vessel, positioning a branch portion of a stent present in the system proximate to a branch vessel, and inflating first and second balloons thereby expanding a main body and branch portion of the stent.

Abstract: For extracting a liquid (such as oil) from a porous medium, the liquid is subjected to pulses that propagate through the liquid flowing through the pores of the medium. The pulses cause momentary surges in the velocity of the liquid, which keeps the pores open. The pulses can be generated in the production well, or in a separate excitation well. If the pulses travel with the liquid, the velocity of travel of the liquid through the pores can be increased. The solid matrix is kept stationary, and the pulses move through the liquid. The pulses in the liquid can be generated directly in the liquid, or indirectly in the liquid via a localized area of the solid matrix.

Abstract: 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.
