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 stent also comprises a branch portion that is deployable outwardly from the stent body into a branch vessel.

Abstract: Apparatus and method are provided for treatment of a bifurcation of a body lumen. The apparatus includes an elongated catheter body having a proximal end and a distal end. A balloon is associated with the distal end of the balloon catheter. The balloon includes a main vessel balloon for treating a main vessel of the bifurcation, and a branch vessel balloon for treating a branch vessel of the bifurcation. The branch vessel balloon includes an accordion configuration capable of being expanded from an unexpanded collapsed accordion configuration to an expanded accordion configuration extending into the branch vessel.

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: 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 anastomosis delivery system for delivering a connector having at least one backwards spike having a bent tip, comprising: a hollow guide sheath; and a hollow, axially slotted section, fitting within said sheath, said section having a flared configuration and an unflared configuration and wherein said axially slotted section is adapted to contain at least a part of said connector and to limit axial motion of said connector when said section is in its unflared configuration.
